Two Women Killed After Night Out: A 48 Hours Investigation

On the evening of November 12, 2021, a seemingly enjoyable night took an unexpected and tragic turn for architect Hilda Marcela Cabrales, 26, and her friend, 24-year-old model Christy Giles, when they went out to a nightclub in Hollywood and later to a warehouse party in East Los Angeles. The series of events that transpired that night and the somber aftermath have since been the forefront of a gripping investigation, featured in the "48 Hours" episode titled "Dead Girls Don't Talk," which aired on March 29 at 10/9c on CBS and is also available for streaming on Paramount+.

The Night Out and the Unexpected Disappearance

What began as a carefree night of celebration quickly took a sinister turn. Jan Cilliers, Christy's husband, had been in San Francisco that weekend, and upon waking up to check his wife's phone location, he discovered it had moved to an unfamiliar Los Angeles address. As time went on and Cilliers received no response to his messages, his concern grew into a state of raw panic when he later found out that Christy's phone had moved to a hospital about three miles away from the unfamiliar location.

Christy and Hilda's Disturbing Fate

Tragically, Cilliers learned that Christy had been dropped off at the hospital by two masked men in a black Prius without license plates. Despite their claims of being good Samaritans, Christy was pronounced dead on arrival, leaving her husband devastated and shocked. Meanwhile, Hilda had also been taken to the hospital by the same vehicle and under similar circumstances. She was found in critical condition and, unfortunately, passed away two weeks later after her family made the heart-wrenching decision to take her off life support.

The Urging Investigation

Eager to unravel the circumstances surrounding their tragic ends, LAPD detectives had a significant advantage thanks to the phone location sharing habits of both women. Within hours of Hilda being dropped off at the hospital, the detectives were on their way to the mysterious address at 8641 West Olympic Boulevard, where they discovered it was the residence of David Pearce, the owner of a black Prius, and his roommate Brandt Osborn. This tip proved crucial in the investigation.
