Sneak peek: Jocelyn Peters and the Notebook | Forensic Files

500 C police department, can I help you? >> I just got home and the door was open and I walked in
and I think she my girlfriend has been shot. >> Where was she shot at? >> It looks like the head.
>> Did you see who did it? >> I don't know. I can't go in >> This victim resided in an apartment
inside the building. Uniform officers had already been there. The first thing we do is we're going to
go in and we're going to see where our victim is. My name is Mark Biandolino. I'm a
retired homicide detective from the city of St. Louis and I investigated the murder of Jocelyn Peters [music] from
March 24th, 2016. >> This isn't someone who would accidentally leave a door [music] open.
She was responsible, one of the most responsible people I knew. It just didn't make sense.
>> She was a strong force, fierce advocate for children, loved them dearly, and everyone was going to succeed in her
classroom. She always wanted to do the next best [music] thing. In her free time, she was always checking out what
she could do differently to meet the kids' needs, what programs there were out there.
>> There are only three to four full-time art teachers at the middle school level.
>> She'd bust into my office, "Hey, I need you to come to my classroom today. I've
got some magic going on >> [music] >> and you need to come and see it." The kids were learning and she cared about
each one of them and whatever they needed, she gave that to them. >> First person that we're going to speak
to is the person that discovered her. >> And this is Cornelius Green. >> Correct.
>> She truly, truly fell in love with them, honestly, and we all did. He was a principal, he was kind, he was generous.
I mean, he was very attentive to our needs. >> He voluntarily goes down to the police
headquarters. >> You're in Chicago since Tuesday? >> Yes, sir. >> And then you come back today
at 2:57 p.m. >> Yes, sir. I got to the Amtrak at 2:57. >> How did you get to the train station?
>> My brother drove me over there. >> Your Phillip? >> Yes. >> We identified Phillip [clears throat]
Cutler as brother. Was the person who was transporting Mr. Green to the Amtrak station.
Picking him up when he arrived back in town. Other investigators from the homicide
unit were able to go out and [music] pick up Mr. Cutler to conduct an interview.
Detective Harrisburg advised him we're going to speak to you regarding [music] this homicide that occurred today. After
hearing the word homicide, he stands [music] up, he lets out a big sigh, and then he reaches into his back pocket
and retrieves a notebook. He thumbs through several pages, tears out a piece of paper,
and then he immediately puts it into his mouth and begins chewing it. >> [snorts]
>> Whatever was on those two sheets of paper, he immediately wanted to get rid of.
>> There's another sort of loose end in this case, [music] too. >> Yes. We identified immediately organic
materials [music] splattered about in the headboard and around her pillow and then along the floor.
>> What did that turn out to be? >> We identified that as being [music] fragments from a potato. Like
what do you think? Like a baked potato? >> This case is baffling. My name is Tiffany Becker. I'm a retired
Assistant United States Attorney for the Eastern District of Missouri. I couldn't believe
the depravity of the crime itself. >> Hey, do you ever been involved in a case like [music] this before?
>> Nothing like this.
