Police arrest 3 people in investigation of the mysterious death of an Instagram model and her friend

• Police arrested three people in connection to the deaths of an Instagram model and her friend, ABC 7 reported.
• Christy Giles and Hilda Marcela Cabrales-Arzola were left outside two separate hospitals last month.

Three men were arrested on Wednesday in an investigation of the deaths of an Instagram model and her friend, who were both mysteriously dumped outside two separate Los Angeles hospitals last month, ABC 7 reported.

Instagram model Christy Giles, 24, was found dead on the sidewalk outside Southern California Hospital in Culver City on November 13.

Her friend, Hilda Marcela Cabrales-Arzola, was found unconscious outside Kaiser Permanente Los Angeles Medical Center two hours later and put into a coma. A day before her 27th birthday, she was pronounced brain dead and her family took her off life support.

Giles' husband, Jan Cilliers, confirmed to ABC7 that Los Angeles Police Department made three arrests. The publication gave no further details.

The LAPD did not immediately respond to Insider's request for comment.

Cabrales-Arzola and Giles attended a warehouse party in East LA together the night before they were found outside the hospitals.

The two friends left the party with three unidentified men and went to an apartment in West Hollywood, Giles' mother and Cilliers previously told multiple media outlets.

The women were meant to leave the apartment to attend another party but never made it, Cilliers told the Daily Mail last month.

Cilliers told the Mail that while at the apartment, his wife sent a text message to Cabrales-Arzola, saying, "Let's go" alongside a shocked-face emoji. Cabrales-Arzola responded that she was calling an Uber but the two women never got in one, Cilliers told the Mail.

The families of both women have previously said they suspect foul play in their deaths.

A toxicology report found that Cabrales-Arzola had heroin in her system, KTLA reported, but Cilliers said both women would never take heroin voluntarily.

On Tuesday, Cilliers dedicated an Instagram post to Giles, writing: "It's now exactly one month since you were so suddenly taken from us. Time has never moved so slowly, or so quickly."

"Life will never be the same without you," he added.
