Hunted | Full Episode | Forensic Files

[music] He was going out late at night. [music] >> He was out trolling around looking for
rape. If you want to find targets, just like a hunt and hours and hours walking around
various different apartment complexes. I'm a single mother. I try not to live a paranoid life. I
mean, I want to think that people are good and so I don't look for bad things. I suppose because I wasn't looking for
that. [music] It just never occurred to me that it could happen. Um, Julie had one night she left one of
the windows open. >> So, I climbed in. She was sleeping in the bedroom. >> Did you have any idea that somebody was
stalking you? >> Not at all. >> Watching your every movement? >> No. >> Walking in and out of your house?
>> No idea whatsoever. >> Everyone kind of has a different reaction. You know, you kind of be
paralyzed with fear, just start screaming right on top of their lungs. others would, you know, be quiet.
>> Well, I just screamed and he just told me, kept telling me to shut up. Had a black mask and the only thing that
showed was his eyes, that he had a a gun in his bag. If I didn't shut up, he would he would kill
me. >> There's definitely a rhythm. There's definitely a time pattern of when I'm
normal and when I'm raping guys. >> He came in my room and jumped on my back. He told me all he wanted to do was rape
me. >> I was terrified. These women had been through something so horrendous. >> The type of person that committed these
crimes was a heinous individual. I did think that he had done this before. [music]
>> I'm thankful that this case came to me. I knew we had to catch this guy. He would do physical surveillance.
>> There was no secret thing that they all had in common, just looking for victims.
Part of the desiraability of it was that it was random and that I didn't know them.
>> This one is serial. It kept going and going and going. >> What has turned me on
is fear. You know, I basically feed off of it. >> I felt scared. I felt scared for um
other women in society. I felt afraid for myself. That's why I think we were so driven. And
>> it's a question that you ask again and again. Is it somebody that has been involved in um more horrific things in
the past? >> The thing is when you go to that cycle, we were in predator mode. >> I definitely felt like we were up
against the clock. It was ticking. I could hear it. I could feel it. I felt like we just had to get him off the
street. >> [music] [music] >> I knew that she lived a long time. I knew that, you know, she was vulnerable.
I have kind of a moment of weakness, I guess. >> But as a single woman, it just never
occurred to you that you were vulnerable living by yourself? >> No. >> It was just after midnight in Aurora,
Colorado, 10 miles outside Denver. This woman, who we will call Mary, had no idea she was being stalked by a strange
man. I brought it down to that one. Saw that the bedroom light was on. All I knew she was there.
>> In October of 2009, Mary, a 65year-old grandmother, was jarred awake by a large
masked man. He climbed on top of her, tied her up, cut off her clothes, [music] and for the
next 4 hours brutally raped her. I just live moment to moment. Whatever he told me to do, I did it. Did
you ever think I'm going to try to escape? I never felt like I had the opportunity.
>> Then, as if all that hadn't been enough of a violation, he pulled out a camera
and photographed her. >> Did he threaten you um with the pictures? >> Yes. He told me that if I called the
police, he would put it on the internet. When he was done, he went about carefully cleaning anything that could
have any trace of his DNA, stripping bed sheets, and removing her clothes from the scene. Finally, he brought Mary to
the bathroom and ordered her into the bathtub. [music] >> When he told me to fill the bathtub,
that really made me nervous. >> Did you think he was going to kill you? I thought he was going to drown me.
>> He warned her not to come out of the bathroom until he left. She waited like he told her in that bathtub, cold
and frightened for more than an hour. >> What was going through your mind in that
hour? Is he gone? Is he gone? I wonder if he's gone. Investigators were able to find some of
the rapist's DNA on this teddy [music] bear in Mary's house, but when they ran it through national databases,
they couldn't find a match, and Mary's case went cold. Two years later, and 25 miles away,
Golden, Colorado police detective Stacy Galbreth. >> I take all my cases pretty personally.
She was just starting her shift when a call came in. >> The patrol was being dispatched to a
sexual assault that had just occurred. >> Galbreth immediately headed to the scene.
>> Right here is the building that the golden victim was living in at the time of her attack
>> and spoke to the victim, [music] a 29year-old woman who said she was in bed when she was attacked. She remembered
hearing a noise and then a masked person came into her bedroom, straddled her and um he threatened to
shoot her. He had a he had a gun with him. He sexually assaulted her, photographed her
and had her take a shower and then left. >> Crime scene technicians found little
evidence. He took everything that we could have collected DNA from. He took the bed covers. He um instructed her,
you know, to use soap, to use toothpaste, to basically wash away or take away any of the evidence that we
needed to to solve the case. >> But the victim did remember that the attacker was white and blonde because
she could see the hair on his arms. >> This victim was very articulate. She wasn't, you know, visibly shaken. She
wasn't crying. She wasn't emotional. >> She was able to sketch this image of a masked man and this distinctive
egg-shaped birthark she saw on his calf. >> She was able to give all these very detailed bits of information that at
some point in the investigation, these are things I'm going to be looking for. Her attacker brought a pair of pink high
heels and made her wear them while he took photos of her with a pink Sony Cybershot like this one. Outside the
victim's apartment, a security camera recorded a suspicious white Mazda truck, but the plates
weren't visible. And in the snow, a single shoe print >> and it came back as an Adidas. So, we
knew if we could either find the right person and they were wearing that shoe or had that shoe, you know, we could be
a little bit closer. >> But none of what the victim recalled was enough to break open this case. And
Detective Golth, now leading the investigation, was deeply frustrated. Later that night, she did what many
married people do and vented to her spouse who just happened to be a police officer in a neighboring town. and he
immediately just kind of looked at me and said, "You know, I think we've had that here in recently." And what he
picked up on was that they were made to shower and for a certain time period and
basically wash away the evidence. >> First thing the next morning, her husband put her in touch with the
lead investigator on that case 19 miles away in Westminster, Colorado, Detective Edna Hendershot. It seemed
pretty obvious that there was some connection. >> Both of their departments assigned the
detectives to work together on the cases. The description of the attacker was almost exactly the same.
>> A white male. I'm about 6'2, 180. He had light colored hair. >> She also described him as a little bit
chubby. And >> I said, "My victim had a pink Sony Cyersshot camera that was stolen from
her." and Stacy um immediately keyed on that and said, "My victim was photographed with a pink Sony Cybershot
camera." >> What's more, Detective Hendershop was able to link the rape of 65-year-old
[music] Mary in Aurora to the same attacker. That made for three attacks in 2 years.
And at Detective Hendershot's crime scene in Westminster, another piece of evidence
>> turned out to be glove impressions that were alongside the railing outside of the apartment where the Westminster
victim lived. >> So, not quite a fingerprint. >> Definitely not a fingerprint, >> but but impressions from a glove. And we
describe them as a honeycomb pattern. >> What's the profile you have on this guy?
Who do you have in your mind? Who is this [music] guy? We're thinking um potentially military. He knew what he
was doing. I was kind of scared maybe he could be in law enforcement. I kind of felt like
like do any of my cops here look like look like this guy? Does anyone have this mark on his leg that my victim is
is describing? In all the cases, the rapist told his victims he'd been stalking them for months,
watching their every move and breaking into their homes during test runs. If they couldn't stop him soon, they knew
he would strike again. He's hunting for his victim and then the next victim and then the
next victim. Did you ever consider that he may be a serial killer and not just a
serial rapist? >> I think everything was on the table at that point in time. >> Your time is spent bad night and
hunting. >> Once you pass the island and you kind of, you know, almost go past this point
of no return. As you get more proficient, you start making less mistakes. >> He was educated enough to know what we
were looking for and know what he needed to take to throw us off. >> He was experienced with what he was
doing. Probably be a little bit difficult to find. Colorado detectives Stacy Galbreth and
Edna Hendershot were working overtime to find the pattern behind the attacks. Our victims spanned age ranges. The
victim in Aurora was in her 60s. The victim in Golden was in her 20s. The Westminster victim was 59 years old.
Trying to figure out what is it that they have in common that would make them targets for this particular individual.
That was very frustrating because there was no consistency other than that they were women.
>> But there were pieces of a puzzle. That glove print on a railing in Westminster.
>> The Adidas shoe print in the snow in Golden and a pink camera like this one used to photograph the victims during
the attacks. But nothing to pull the entire picture together. He was counting on the fact that we wouldn't talk to one
another, that we wouldn't reach out, that we wouldn't communicate. That's what he was counting on. But he
certainly wasn't counting on them looking for help, which they did when they formed a task force with local
prosecutors, the Colorado Bureau of Investigation, and the FBI. On that task force was veteran FBI
special agent Johnny Grusing. >> Did you have a sense that he's going to strike again?
>> Absolutely. >> He scoured area police files for similar attacks and found a report in nearby
Lakewood that was labeled a home invasion. But when he looked closer, he saw it was
a failed rape attempt. The victim describing a masked man. >> Around 2:33 in the morning, she heard a
dragging sound coming down the hall. That woke her up and she saw a large masked man in her doorway holding a
knife. Then he straddled her, made her go face down. However, she was able to actually lift
up, turn around, and face the man and tell him that he didn't he was not supposed to be there and this was not
going to happen. >> If she's willing it not to happen at this point, >> correct? She was very brave.
>> The woman started screaming a man's name, yelling for help. [music] The attacker
thought someone else might be in the Lakewood house. >> And he makes the decision. He's going to
let her go for a second and check the room. By the time he jumps off of her and checks the room, she gets on her bed
and dives out a window that is about 1 ft high by 4 ft wide onto the concrete outside.
She shattered her vertebra that two ribs were broken and her lung was punctured from that fall. But she still got up,
ran to her neighbor's house, and called the police. >> Her police file had been sitting dormant
for half a year when the Denver area task force finally came across it. That one case turned out to be a treasure
trove full of evidence and information that definitively linked all the attacks together.
The evidence in the Lakewood case was absolutely key in linking this to one attacker.
>> [music] >> Specifically, each piece of evidence from one of the other assaults had a
connection to the Lakewood case. For example, the glove like this. This glove pattern was found in the
Lakewood case. And this pattern was also found in the Westminster case. And remember that Adidas shoe print in the
snow in Golden. There was a perfect match in Lakewood. Then at the end of a long task force
meeting, a mention of a suspicious white vehicle seen at the Lakewood attack. >> So this is the bulletin that um the
crime analyst in Lakewood held up at the conclusion of our meeting. >> It described a white Mazda pickup truck.
>> That was when I am like, "Okay, there we had a white truck and it's just like
that." I just knew in my heart that that was that was it for that truck to be in
that neighborhood in Lakewood and also be in mine that had to be significant. Now the task force had a plate number
and when they dug through their database they came across this picture [music] of
the truck with a white man standing next to it about 6 feet tall. When I saw this truck and the man
standing next to the truck, I thought that that looked like what all the victims um who had been attacked
described. That was that aha moment. [music] >> We have a truck that's in the same two
areas. And now we got to see who it belongs to and who is this guy. >> And who was that guy?
>> Marco Liry. >> Had you ever heard that name before? [music] >> No. >> Was he on anybody's radar?
>> No. Mark Patrick Olirri, a man fitting the very profile described by several of the
victims. He had a military career that took him all over the world from Washington State
to Korea. The 32-year-old Olirri was separated from his wife and studying at a local
community college. >> Did he have any prior criminal history whatsoever? >> Insignificant.
>> Yeah. No assaults. >> No. No violent crime. >> No. >> Nothing to indicate that this guy was
capable of what he was being accused of. >> Nothing like that. >> I mean, you got the truck,
you got the guy, you got an address. He's right there. Like, did you want to just get in your car, go over, bang on
the door, and take him right then? >> No, we couldn't do that yet. >> I know you couldn't, but did you want
to? >> Well, we needed to make sure. [music] And so it became important at that point
in time to start conducting surveillance on him, attempt to get the DNA from this
individual. Marco Liry, suspected of stalking and attacking so many women, was about to
become haunted himself. We're in Lakewood, Colorado, and this is the neighborhood where we set up on
Marco Lir's residence. We waited and watched. >> The task force finally had a viable
suspect in Marco Liry, and Agent Grusing's team didn't have to wait long for things to pick up. fast
>> and they see the truck leave and it looks like the registered owner gets in it with a female.
>> As part of the team followed the couple to lunch at this restaurant, Gruing stayed behind, hoping to install a
surveillance camera on the house. But first, he needed to make sure no one else was home.
>> I walked up through this driveway. We knocked on that white door where the light is and Mark Oly appeared in the
doorway. >> What you were not expecting? >> I was not expecting. >> He really wasn't. He thought he had just
seen Oly drive off in the truck. >> And what was his demeanor when he came to the door?
>> He looked a little surprised. He was curious, I would say, more than anything
to see why would we be knocking on his door. >> So, you had to do a little tap dance.
What happened? I pulled out the flyer that I had ready and it was of a person we were looking for in another
investigation. >> He looked at the sketch, said it did not look familiar. He said that his brother
lived there with him. We didn't even know he had a brother until that moment. >> It turned out Gruing's team was tailing
Michael Olyri, Mark's younger brother, who looks an awful lot like him. They collected the cup that Michael drank out
of at lunch, hoping that strain of DNA might match the DNA on that teddy bear and other samples they obtained. And
what did it uh reveal? >> It revealed that strain of male DNA from the Ori family was on all of our victims
possessions. >> But they had no idea which Oly brother was responsible. So they went to find
out. What are you feeling? You're this close to this guy. >> I'm ready and I'm praying and hoping
that we don't lose him somehow and someone else gets hurt. >> At 6:00 that Sunday morning, the team
knocked on the Olirri's door, guns drawn. Stacy found herself face to face with Marco Liry.
>> He just went pale just like [music] you could just kind of see the life go out of him for a second.
He had real baggy pants on. So, I lifted each pant leg up and I saw the uh eggshaped birth mark on his calf.
>> It was identical to that unusual birthark that Galbra's [music] victim had described on her attacker's leg.
>> I said, "Turn around. Put your hands behind your back. You're under arrest." >> They knew they finally had the right Oly
in custody. >> It's gratifying to finally put someone like that in handcuffs. Leave these
officers with you here for just a minute. Okay. >> Marco Liry seemed strangely amused by
the circumstances. [music] >> Guard duty >> and he would not cooperate. >> I need you to talk to an attorney.
>> At that point, we were wanting to see what was in the house. >> A search warrant of his home yielded a
gold mine. He had all of these things that he used to facilitate these assaults just in places about the house.
>> Hidden in plain sight is how I would >> hidden in plain sight. >> So in his closet we uh came up with
we came up with this these shoes. >> What did you think? >> I knew those were them. That's it.
They were a perfect match to those shoe prints found near two of the crime scenes.
Just inside Olyri's front door, a pair of gloves with that distinct honeycomb pattern. And that wasn't all.
This is a pink Sony Cyersshot camera that was collected from the office of Li's residence. He had kind of some
bookshelves and he had it just kind of propped up on a shelf. It was the exact camera that was stolen
from the Westminster victim and used to photograph the golden victim. And then perhaps most disturbingly, they came
upon this backpack full of items had brought with him to perpetrate the rapes. So these are the high heel shoes. Which
victim? >> Golden. >> So this is your victim. >> Yeah. >> You get quiet when you see him. I I
actually haven't seen these things beyond pictures. >> Why do you get quiet? It's just sad.
>> Yeah. You know, it's just a thing until you know the details of what the thing
was used for, >> right? You don't usually find this, in my opinion, this much cooperation.
>> Mhm. >> Cooperated every I mean, just [music] >> he didn't seem to be really working hard
to hide everything. He wasn't expecting us. >> But in all that evidence, there was
nothing to link Marco Larry's brother, [music] Michael, to any of the attacks. >> At this point in time, you do not
believe he was involved with it in any way. >> No. >> It was in Mark's room, in Mark's
possessions, that the detectives would make a worrisome discovery. Hard drives containing hundreds of pictures, and not
just of the four victims they knew of. Deputy Jefferson County District Attorney Bob Winer.
>> There were photographs that depicted other women in what I think can only be characterized as a rape scenario.
>> I wondered if they were victims of sexual assault, if they were um even alive anymore.
>> The investigators had to find them. [music] In Olirri's phone, they found he had called this woman numerous times.
Her name is Amy. So, we're now on our way to meet Amy. Amy wasn't a victim. She was actually Olyri's girlfriend.
[music] Now, can you imagine you find out the guy you had dated was actually a serial
rapist at the time the two of you were together? I mean, what would you say? How would you react? We're about to find
out. >> Hi, Amy. Moren Maher with 48 Hours. Nice to meet you. Have a seat. Thank you so
much for doing >> [music] >> So, I was at work and [music] a message was on my phone
from special agent John Gruing [music] from the FBI regarding Mark Olri. In early 2011, then a 35-year-old
bartender, Amy was unsure why the FBI would be calling her about her ex-boyfriend.
>> He said, "Well, I'm sure you know what's going on with Marco Liry." And I said,
"No, actually, I don't." And he said, "Well, it's been all over the news. He's committed [music] a series of
rapes." >> It was hard for Amy to believe. She'd met Marco Liry on the online dating site
okaycid in 2009 and the man she thought she knew presented himself very differently.
>> He was pretty chivalous and protective and >> was he charming? [music] >> He was very charming. Like he was really
fun to talk to. We talked for hours at a time quite frequently. There was a lightness to him even though he had a
dark sense of humor. >> But it didn't last long for the couple. We attempted a sexual relationship, but
things did not go very well in terms of chemistry. Mark needed the other person to be
scared, >> the fear. >> Yes. >> And the dominance? >> Yes. >> And did you ever see that violent side
of him? >> No, I didn't see any violence. Like, I knew what he liked and what turned him
on. But I didn't show him fear >> in any real way. And he knew I wasn't scared. >> It was tofu to somebody who wanted
steak. >> Amy had no idea that when she wasn't with Mark, Mark was out praying on
women. >> I talked to Special Agent Gruing for a long time. And then after I got off the
phone, I went and threw up. It was pretty upsetting to me. >> As Amy struggled with Marco Liri's
arrest, a few miles away, a detective broke the news to Mary. [screaming] >> First, I didn't believe him. I said,
"You sure?" He says, "Yep, we we got him." That's what he said. "We got him." >> Did you feel a sense of relief?
>> Oh my. Yes. There were so many victims and he [music] was so sick. >> Mark Patrick Olirri was charged with
more than 30 counts of sexual assault, kidnapping, and burglary. Prosecutor Bob Winer
>> to have actual photographs uh as disgusting as they were of the actual rapes ended any speculation as to
whether we had the right guy. Faced with overwhelming evidence, Olyri agreed to plead guilty to the sexual
assault charges. >> He was meticulous in the way he stalked these victims. >> But it was at his sentencing hearing
that fireworks really began. >> I am a sexually violent predator. >> Surprisingly, he has the chance to
address the court as well. He took advantage of it. >> And I'm out of control. I've been out of
control for a long time. Words are just inadequate to describe uh how just horrible I you know I acted and and I
can only hope that you know that my sentence today will satisfy them. >> His sentence would more than satisfy
over 300 years in prison. a staggering number. In >> some crazy way felt sorry for him.
He said he was [music] just going from one prison to another. >> So he was in his own prison.
>> And something else he said at the sentencing caught the detective's attention.
>> He said that he would be willing to answer questions. And in law enforcement it's that's the, you know, that's the
green light. They were about to get a rare look into the mind of a serial rapist.
>> Are you okay? >> Yeah, I'm all right. >> Johnny Grusing took the lead, >> playing to Olyri's ego.
>> I told him that our profilers were very interested in him because of how intelligent he was and he seemed to like
that. >> You know, you hear psychologists say, you know, rape is a crime about power and control. That's not accurate.
Power and control are a means to an end. What has turned me off is fear. >> Talked about how his pendulum would
swing and he could not control it. He would have to fill that need and that's the monster talking to him.
>> You know, after a while the the monster kicks in and >> he never won any of these battles with
the monster. And Gruing saw that monster [music] up close. Oly described his feelings after one of the rapes.
I still remember this moment is that's when he leaned back and smiled. >> I got some sort of satisfaction out of
it. It was like I was just eating Thanksgiving dinner. Olirri says even as a child he had rape
fantasies but didn't act on them until he was in the military on a tour of duty in Korea where he tried but failed to
rape two women back in the states. He was determined not to fail again. >> So I got to do it for real and just be
done with it. And then he decided that he was going to use his military training
to figure out a way to stalk his victims, to not be caught, and to satisfy this urge that would come.
>> Brought up one woman he'd been planning to attack. Peek. It was P. >> Julie Pek. Remember her? The single
mother who had no idea Oli was stalking her. checked out her house a couple of times.
I knew she had an alarm system, but um she never used it. >> He was lining her up for an assault.
>> And so I was walking around the back of her house one night. So just as I was
walking by her back balcony, um she opened the door. >> I saw him out there and I said, "What
the are you doing here?" >> Uh get out of here. I'm going to call the police. And I just watched him. He
just turned around, went down the stairs, uh went out to the back, climbed over the fence, and left.
>> Julie, unnerved, always set her home alarm after that, but never thought about it again until the FBI called her.
>> It was very hard for me to process it. >> But the FBI didn't tell her everything.
>> Did you know that at one point he was in the house and you were asleep? >> I did not know that. walking in and out
of your house? >> No. >> Taking things from your place? >> No idea whatsoever. >> And what about those hard drives with
the hundreds of photos of other women? Ori wasn't willing to discuss anything that he had not plead guilty to.
>> Yeah, I won't tell you about any other cases. >> Even behind bars, Olri wasn't done
tormenting women. Before the interview ended, he had a special message for Detective Galbrath.
>> Hi, Stacy Galbreth. Bet you wish you could have shot me. >> Huh. Was it unnerving?
>> Yeah. You know, I didn't I didn't sleep well that night. >> It wouldn't be the last sleepless night.
>> We [music] discovered another victim. But what happened to that woman was far
worse than the detectives could imagine. Among the hundreds of photos found in Marco Lir's home, a picture of a young
woman bound and gagged stood out. >> In that case, he actually photographed her like he'd done our other victims. Um
but he um thoughtfully photographed her with her driver's license on her. >> So you knew exactly who she was?
>> Yes. >> She was an 18-year-old woman whose identity we are not revealing living
just outside Seattle in Lynwood, Washington. >> And did you contact that police department [music] in Washington?
>> Oh, right away. >> It turns out they knew about her. They even had a rape report from 2008.
only. They believed it was a false report. Lynwood Police Department Commander Rodney Conheim.
>> She reported that she woke up to find an intruder in her bedroom standing at the
doorway. He was armed with a knife. He approached her, bound her hands behind her back, gagged her, blindfolded her,
had her roll over, and then he raped her for a period of time. But during the investigation, they began to doubt the
young woman's truthfulness. One detective even threatened to charge her if she was lying. The young woman gave
an interview to NPR's This American Life. >> He told me that if uh I took a lie detector test and it came back that I
was lying that he was going to take me to jail himself. >> After that, she quickly changed her
story. She says that she thought she may have dreamed that this occurred and at one point she said that it didn't happen
and ultimately she was given a citation for false reporting. [music] >> She was forced to pay a $500 fine and
plead guilty for lying about being raped. Detective Golreth couldn't [snorts] believe what she was [music]
reading. >> I actually felt emotional. I knew that was wrong because I could prove their
case now. And what was their response when you called and said, "Hey, you know that case of that young woman who you
thought was lying and you charged her? Guess what? I got a picture of her after she's assaulted from the actual rapist."
>> And they came out immediately. >> Mhm. >> I was stunned. It's an absolute nightmare. Everything that she told us
was the absolute truth. She was isolated, alone, and then nobody believed her. That's a lot to digest.
The commander and his team headed straight to the young woman's home. 3 years had passed since she had reported
her rape. >> She was very surprised to see us and [music] we told her what we had learned.
She was stunned. She was quiet at first. Um she began to cry. It was heart-wrenching to know that she had
lived with this alone for all those years. The woman's charge was expuned from her
record. Her fine was reimbursed and she eventually settled a lawsuit with the police department for $150,000. [music]
>> Well, we learned many lessons here at the Lynwood Police Departments on the heels of this investigation. We had
outside groups come in to teach officers and detectives um ways to investigate sexual assaults. Not every victim of a
violent crime reports it in the same way and that we need to understand that as strange as some circumstances seem. They
can be true. >> It's an observation not gone unnoticed by the rapist himself. >> If Washington had just paid attention a
little bit more, you know, they probably probably would have been a person of interest, you know, earlier on.
Olirri was charged with that woman's rape and yet another similar sexual assault in Washington. He plead guilty
in both cases, bringing the known number of victims to six. But Stacy and Edna believe it [music] doesn't stop there.
>> Oh yeah, absolutely. There's more. >> Olirri had encrypted computers that investigators are still unable to open.
>> It went to Quanico. It went to the FBI lab here. Um, >> nobody can get into it.
>> Nobody can get into it. And I was told that probably no one ever will. >> All of this begs the question, if Marco
Liry was willing to give such explicit details about the terrible crimes they already knew he had committed, what
possible horrific things was he still hiding on those hard drives? >> You think it's worse?
>> Don't know. The other thing we wonder is, could someone else have been involved?
>> Ex-girlfriend Amy wonders the same thing. >> It sounds to me like maybe he's protecting somebody else if he's willing
to fess up to everything that he's done, but he's not willing to turn over all of
the information that he has. >> But Mary is hoping other victims of Oly will come forward. Well, I think the big
thing is [music] just that rape victims don't have to be ashamed. He kept getting away with it and he wanted to do
it again. And each time he did it, he got a little more cocky about what he was doing and a little more dangerous.
>> And there's no fear in your life now associated with it? >> No, I won't let it happen. I won't let
him instill [music] fear in me. I don't want anybody to do that to me. >> Her [music] strength fuels the work that
Edna and Stacy have committed their lives to. He's only [music] behind bars because of
the work that you did together. >> Right. But it's not two people. >> Mhm. >> Right. It's not It's not three people
with Johnny involved. [music] It's a whole group. It took the entire group. Knowing that you pulled someone like
