Sneak peek: "Dead Girls Don't Talk" | Forensic Files

Powerful opening statements in the Hollywood overdose murder trial. David Pierce sent Brandt Osborne on trial for
the deaths of two women, model Christy Giles and her architect friend Hilda Cabrales. This trial will not change
what happened and will not bring my sister back or Christy. Christy's plan for the evening was to go
out with some friends and have a fun night. Aloha. My name is Jan Cilliers and Christy was
my wife. Christy loved to spread joy and laughter wherever she went. Hilda Massola just moved from Mexico.
She seemed very lovely and they were becoming fast friends. My sister did enjoy going out to
parties. She liked dancing and the music. I remember seeing her Instagram. She was
posting stories of that night. She sent me a couple of text messages. Her last text message to me was around
1:00 or 2:00 a.m. And throughout the day I was trying to text her and there was no response. You're tracking Christy's
phone. Yeah. Is this an address that you recognize? It's not an address I know. Around 5:00 p.m. I saw her location had
suddenly moved to an emergency room hospital. My level of panic was growing and growing.
I just knew that I had to try and get to the bottom of what happened. You blast out this address.
And very quickly you get responses. Yeah. What are those responses? That there's somebody that lives at this
location that is a very unsavory person. David Pierce. Yeah. He passed himself off as a big shot
Hollywood producer, but he was a con man with an alleged history of sexual assault.
It wasn't clear what happened. We just knew she overdosed and to me my reaction was who did this to her? So when you
heard overdose, you immediately thought drugged. Yeah, drugged. Definitely not something that she would
have done to herself ever. It's just not her. Got a call at home. Apparently overdose.
Christy she she was deceased. Hilda was still on life support at that time. I give as much information as I can to
the detectives. Jan had put a number of things out on social media and it spread
like wildfire. People recognize this guy right away and they were urged to to call us.
Authorities say seven more women had come forward claiming Pierce sexually assaulted them as well.
Jane Doe number one. Jane Doe number two. Jane Doe number three. Number four. Number five. Number six. Number seven.
Being a Jane Doe, we are the voice of both Christy and Hilda because they can't talk. Defendant Pierce wanted them
to die. He wanted them to die because dead girls don't talk.
