3 men arrested in connection with deaths of model, friend drugged and dropped at L.A. hospitals

The friends went out for a night of partying in Los Angeles and never returned home.

Three men have been arrested in connection with the deaths of a model and her friend, who were dropped off unconscious at different Los Angeles hospitals last month.

Investigators said they believe that the model, Christy Giles, 24, and her friend, Hilda Marcela Cabrales Arzola, 26, "were given drugs and overdosed" at a home on Olympic Boulevard on Nov. 12.

Three masked men in a black Toyota Prius without license plates dropped Giles at Southern California Hospital at Culver City early Nov. 13, Los Angeles police said.

She was unconscious and was soon pronounced dead.

The same men dropped Cabrales Arzola at Kaiser Permanente West Los Angeles Medical Center a short time later, police said.

She was unconscious and in very critical condition. She was declared dead on Nov. 24, days before her birthday, the Los Angeles County medical examiner said.

The coroner has not determined the causes of death and has requested more studies, a spokeswoman for the office said.

The three men, David Pearce, 37; Michael Ansbach, 47; and Brandt Osborn, 42, are charged in connection with the deaths, police announced Thursday.

Pearce is charged with manslaughter and was being held on $1 million bail. Ansbach and Osborn are charged with accessory to manslaughter and were being held on $100,000 bail.

"Based on the investigation, the LAPD is concerned that there could be other victims in our community who could have been drugged by one or more of these men," police said in a statement.

It is unclear whether the men have lawyers.

Giles’ husband, Jan Cilliers, told NBC Los Angeles that his wife was party-hopping with Cabrales Arzola on Nov. 12. Both women had birthdays in November; Giles celebrated hers the week before she died.

They followed a group of men to go to an after-party, another friend who was with them told Cilliers, he said.

He said he and Giles shared locations on their phones. On the 13th, when Giles had not come home, Cilliers checked on his wife's location. Her phone was in the emergency room at Southern California Hospital.
