PASADENA (CBSLA.com) — Police Wednesday announced the arrest of a third suspect in connection with the assault and robbery of an 87-year-old man who walked near the Rose Bowl.

According to the Pasadena Police Department, Gabriel Anthony Mixco, 19, of Rowland Heights, surrendered to police Tuesday evening following a press conference held by Police Chief Phillip L. Sanchez.

Around 5 a.m. Friday, the victim walked on West Drive, north of Salvia Canyon Road, when four suspects assaulted him and stole his pouch that contained money and identification, officers explained.

The suspects fled from the scene in a black 2003 or 2004 Honda Accord Coupe that has a sunroof.

Surveillance video at a nearby convenience store captured the suspects attempting to use the victim’s credit card.

The victim was located suffering from severe head trauma by other exercisers in the area. He has remained hospitalized in critical, but stable condition since Saturday.

According to police, Juan Antonio Medina, 19, of Rowland Heights, and Dominick Tobiah Guzman, of Hacienda Heights, both turned themselves into police on Monday.

The fourth suspect remains unidentified and at large.

Detectives described her as a Hispanic female teenager who has long brown hair. She was last seen wearing a dark hooded sweatshirt that had white lettering on the front of it.

Mixco, Medina and Guzman are being held on just over $1 million at the Pasadena City Jail on suspicion of attempted murder and robbery.

According to police, the case will be presented to the Los Angeles County District Attorney’s Office on Thursday.

The investigation is ongoing.

Anyone with information regarding the identity of the fourth suspect is urged to contact the Pasadena Police Department at (626) 744-3953.
