2:30Powerful opening statements in the Hollywood overdose murder trial. David Pierce and 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 Celia and Christy was my wife. Christy loved to spread joy and laughter wherever she went. Hilda Marcella just moved from Mexico. She seemed very lovely and they were becoming fast friends. My sister did enjoy going out to parties.

3:21She 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 or 2 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 p.m., I saw her location. I had suddenly moved to an emergency room hospital. My level of panic is 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.

4:06Yeah. 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.

4:25It 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, apparent overdose. Christy, 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 recognized this guy right away and they were urged to call us. Authorities say seven more women have come forward claiming Pierce sexually assaulted them as well.

5:15Jane 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.

5:42John Convigliani reports. Dead girls don't talk.

5:51For a fresh case, it's all on you. There's no, no one else is going to solve this thing for you. It's you and your partner. That's it. And in November 2021, Detective Jonathan Vanderlei and Detective Calvin Yu had to figure out why a lifeless woman was left at this emergency room. This video from Southern California Hospital shows staff pulling a woman out of a black Prius and helping her onto a stretcher while two men look on. When the stretcher moves into the ER, it becomes clear the car has no license plates. Detective Vanderlei would later learn that the two men told the staff they found the woman, quote, passed out on the curb somewhere nearby, and they were trying to be good Samaritans.

6:45They left without giving their names or phone numbers. They were masked, disguised. This must be adding up to something that sounds very sketchy to you. Very sketchy, but then you still have to figure out if an actual crime occurred. The woman was Christy Giles, and her mother, Dusty, will never forget the call that came from the hospital, telling her her 24-year-old daughter was dead from a drug overdose. And I said, what do you mean she didn't make it? And then I hung up and I fell apart. Two hours later, at a hospital just two miles away, a second woman was left at another emergency room by the same two men, also in a black Prius and wearing masks.

7:36They never give their names, never leave their phone numbers, license plates, anything like that. That was Hilda Marcela Cabrales, the 26-year-old architect was still alive in the ICU and fighting for her life. And in Durango, Mexico, her mother, Hilda Marcela Plasencia, was getting the news about her eldest daughter and namesake. She was very bad. She was intubated. You are a doctor. What was going on in your mind at the time? What happened? What happened to her? Why is she that bad? And in the earliest hours of the investigation, there were only questions. How could this happen to Christy? It was an unimaginable ending to a life bursting with exuberance.

8:30Let's do some donuts! Christy was an adventurer, traveling the world as a high-fashion model for Wilhelmina. She ultimately made L.A. her home. I'm Chrissy Giles, I live in Venice, California, and I am an artist. At 21, her life took a dramatic turn. She met Jan Sillier, a South African-born artist, photographer, and special effects editor, 17 years her senior. They'd been together seven months when the couple went to Burning Man, an arts festival in the Nevada desert, where impulsively, they took a big leap. We just decided to elope. We just got married right there.

9:14We said to each other that, you know, life's very short, so we kind of really just proposed to each other, and the next day we got married. After they got married, Christy started studying interior design in Los Angeles, which led to a new friendship with Hilda Marcella. Hilda had just moved there to start her dream job, recalls her father Luis. I feel very happy for her, but very sad for me because we are very close. No one was surprised that the cum laude graduate of the prestigious university in Monterrey, Mexico, was thriving in L.A., especially her sister Fernanda. She was always making a lot of friends, talkative, outgoing, just having a good time and meeting people that they also like the music, that they are also enjoying dancing.

10:10Dancing, as this video shows, is what the two friends were doing that night. Christy's husband Jan was out of town visiting his father. He knew she and Hilda had planned a girls' night out, starting at Soho House and then on to a warehouse party after midnight to see a favorite DJ. A friend who was with them said they did ketamine, a popular club drug. But by the next day, Jan was on his way home, knowing Christy was gone. In less than 24 hours, your world was turned upside down. Shattered. Yeah. Hilda's father and mother rushed to be by her side. When they arrived, they found their daughter on life support.

10:57My heart broke in a thousand pieces because I saw my baby unconscious. I'm fighting for her life.

11:15I said, is this real? Am I dreaming? I took her hand and I said, mom's here with you. You're not alone. Christy's autopsy revealed that in addition to ketamine, she had cocaine, fentanyl, and GHB, known as the date rape drug, in her system. Are these drugs that Christy would take willingly? I mean, that combination of drugs sounds deadly to me. So, like, no. Jan needed answers. so he began to build a timeline based on the digital trail Christy left behind. Information gathered from her messages and phone, which he was able to track. I wanted to get to the bottom of exactly what happened that night.

12:08He already knew what she'd been doing before she went out for the evening. She was enjoying a lovely sunset. She took our cat for a walk on the beach. Sand panther, sand panther, oh whoa. Those were the last pictures she sent me of herself. And she said, I wish you were here, and I will forever wish that I was there too. Jan was able to track Christy's phone to a residence located at 8641 West Olympic Boulevard. At 5.30am, Christy sends Hilda a wide-eye emoji and says, let's go. Hilda replies, I'll call an Uber. 10 minutes away. The fact that they're both in the same house text messaging each other, they need to leave, is very worrying.

13:00That was the last text message that Christy or Hilda ever sent. That Uber arrived, waited five minutes, and drove away empty. How did you process that? I mean, it's just confirming my worst fears again that they were there at that place against their will.

13:26Wellness routines often fail for one simple reason, and I can speak from personal experience here. They're too complicated to stick with. Too many bottles, powders, and steps usually means they get skipped when life gets busy. Groom's is designed to simplify that.

14:53What's going on in your mind from that detective standpoint when you're about to arrive at a scene? You don't want to form an opinion prior to getting there, but you are kind of mulling over the evidence. You're thinking about it, you're thinking about what questions you want to ask. Acting on information supplied by Jan, LAPD detective Jonathan Vanderlei and his partner headed here to 8641 West Olympic Boulevard a little after midnight on November 14th, only a few hours after getting that call from the second hospital. And this is where the Uber that Chris and Hilda called that night would have waited.

15:36Right out front, yep. Ten minutes between life and death.

15:43It was the home of 39-year-old David Pierce. Police would learn Christy and Hilda had met him for the first time at that warehouse party. Police also discovered Pierce had a registration for a black Prius and found it parked behind the building. It matched the car seen at both hospitals down to the black rims. Pierce lived on the second floor with a roommate, Brant Osborne, 42. There was a light on in the upstairs where the two men live. So I just went up, knocked on the door. Immediately, the lights go out. You identify yourself? Yes, completely. LAPD, open the door, and then just complete silence.

16:30After about 15 minutes, he says, Pierce and Osborne came out. Pierce denied owning a Prius. So I immediately get a lie. Do you leave? No, I interview Mr. Osborne. At first, he says, Osborne denied seeing Christian Hilda at all. You could change the stories numerous times. At first, there's no girls had been at that location whatsoever. I tell him on the interview, I listen, I know you're lying. It's extremely obvious. You're very nervous. Vanderlei says Osborne eventually admitted the women had been at their apartment, but said he'd been asleep and when he woke up, realized Christy and Hilda were in distress.

17:15He said he and Pierce chose to go to two separate hospitals because, quote, we didn't know how it would look. Pierce, police say, did later admit he owned the Prius, but lied again, saying his license plates had been stolen. Vanderleaf says he saw those plates on the ground by the vehicle. Then the men agreed to let detectives inside. Two beds had been stripped. There was a washing machine that had been recently used. It was still wet. Anything else that stands out to you? There was a safe in his room with baggies, which is indicative of narcotics. They said they're for crafts, for arts and crafts.

17:58By now, Vanderley says he knew Pierce and Osborne had dropped Hilda and Christy off and believed Pierce had drugged them. But he didn't have enough evidence to make an arrest. He thought he beat us that night for sure. He was happy. He smiled and said goodbye. Yeah. Thanks, detectives. Yep. But that wasn't where it ended for you? No, not by a long shot. Vanderley knew he needed more evidence and turned to his colleague, Detective Calvin Yu. You hear the name David Pierce. What goes on in your mind? Well, the first thing is, who did he sexually assault this time? Detective Yu had investigated Pierce in 2020 for sexually assaulting a 19-year-old.

18:44She was raped while she was unconscious. The victim said Pierce had given her drugs to knock her out during a date. But the investigation had stalled and wasn't prosecuted at the time. Detective Yu knew Pierce had other prior charges, including another rape charge from 2014 that was also not prosecuted. He has a pattern. His first step is trying to find his victim. So that could be through a dating app, through online listings, or meeting them at bars or events. When he picks his victim, he goes to step two, which is bragging about himself. Pierce relies on lies, detectives say, to set his trap.

19:28He needed to introduce himself as a producer, as a doctor, all these different things. He's none of these things. I think he might have been an intern at the time or something at a production company. An intern. Yeah. They say his next step is to drug his victims and incapacitate them, often with a drink. After they take this drink, he goes to step four, which is the sexual assault. Police would learn both Christy and Hilda showed signs of sexual assault, but they feared they would face challenges making the case. How difficult is it to prove a crime took place when the victims were recreationally using drugs?

20:09This makes the case extremely hard. I told Jan early on that this was going to be a near impossible case to prove.

20:30Yeah, at first it's a whodunit. It just became what actually happened. And that's what was the difficulty of this case. Detective Jonathan Vanderlei says the pressure was on to locate any evidence of what happened after Christy and Hilda met David Pierce that night.

21:00Police did have some luck, starting with this footage from outside that warehouse party. Which they say shows the women leaving with Pierce, Osborne, and a friend of theirs, 47-year-old Michael Ansbach, on their way to Pierce's apartment. Police also uncovered this text exchange from moments earlier when the women were still inside that party. Do you want coke? asks Hilda. Yes, replies Christy. Hilda texted back, I'm in the kitchen, let's do a line. Witnesses say Pierce supplied that cocaine, which Jan says was not a common choice for Christy. Maybe it was late at night and she wanted to get less tired.

21:45It's not something she would do regularly. Police determined the group arrived at Pierce's apartment a little after 5 a.m. The women aren't seen again until 11 hours later, when at 4.30 in the afternoon, a security camera recorded this grainy image showing Pierce with Christy over his shoulder at the top of the stairs. Police say Osborne is carrying her bag. 35 minutes later, at the hospital, Pierce, wearing a black sweatshirt, helps take Christie's body out of the car. Osborne looks on. A full hour and a half later, this dark image shows the men leaving the apartment again, with Hilda. Police say Pierce is carrying her, and Osborne has her boots and coat.

22:39Half an hour later, the Prius arrives at that second hospital, where the men take Hilda out of the car together. It had been more than 13 hours since Christy texted Hilda, Let's go.

23:04For two weeks, Hilda was on life support. With no hope of regaining consciousness, her family gathered to say their goodbyes. Hilda, what were your final moments with your daughter? They were so hard, you know. And I just was asking God to not let her suffer more. I remember telling her that you can leave. And just thanking her for being my sister. I told her, maybe when I pass away, I will see you again. And I give you a big hug, a kiss. The family decided to donate Hilda's organs. Her mom remembers the medical staff lining the halls as the family accompanied Hilda to the OR. The medical team was clapping to honor her, to say thank you for giving life to others.

24:24Like Christy, Hilda had suffered a drug overdose. Toxicology reports would later reveal that she had cocaine, MDMA or ecstasy, and elevated levels of fentanyl in her system.

24:41Police would also learn that while the women were in that apartment, the downstairs neighbor heard someone in pain and moaning on and off for six hours. Police believe that was Hilda. Neither Pierce nor Osborne nor Ansbach called for help. It makes me get angry because she was suffering and nobody, nobody helped her.

25:14How hard is it to prove this narrative when the victims can't even testify on their own behalf? If we were just investing in Christy and Hilda's alone, very difficult. But the district attorney at the time went public, asking other women who knew Pierce to call in, so police could better understand what he did to Hilda and Christy. If you feel comfortable moving forward so that we can evaluate your case and charge it, we're here for you. We started getting a lot of calls. As police continued building their case, Jan received a call that Pierce and Osborne were on the move. He recorded this video of the men loading up a moving van the day after Hilda died.

26:06Police say Pierce had also changed his phone number, and it took them a week to locate him again. So the pressure is on, you gotta get this guy. I gotta come up with something quick, yes. Police have arrested three men in connection with the deaths of a model and her friend last month. On December 15th, 2021, David Pierce, Brant Osborne, and Michael Lonsbach were arrested in connection with Hilda and Christy's deaths. The detectives still knew next to nothing about what had happened inside that apartment. Vanderley says they decided to take a gamble and bring the men in. This is the only way we're going to get the info we need.
