A no-bail bench warrant has been issued for the estranged husband of Diana Gonzalez, 19, whose body was found in a men’s restroom at City College on Oct. 12. The suspect, Armando Gabriel Perez, is believed to have fled into Mexico because his car was found in Tijuana. Perez, 37, is charged with murder and the special circumstance of lying in wait. The case is sensitive in that if Mexican authorities arrest Perez, they might be unwilling to extradite him to the U.S. if the District Attorney’s office seeks the death penalty. San Diego Superior Court Judge Charles Rogers has sealed the arrest warrant affidavit, so details of how the victim was killed on a downtown college campus are not publicly known. No cause of death has been released, but the murder charge states Perez allegedly used a knife to kill the victim. A student found the victim’s body around 10 p.m. in the restroom. Gonzalez had a 9:30 p.m. class that night. She may have been dragged into the restroom and killed, but no one reported any sounds of a struggle. The victim’s parents were waiting for her in a college parking lot and they grew concerned when she didn’t answer her cell phone. Three hours later, detectives told them she was dead. Gonzalez had previously reported to police she had been kidnapped and raped on Sept. 21 and forced to stay in a motel by Perez. Perez was arrested Sept. 24, but no charges were filed against him at that time. District Attorney Bonnie Dumanis declined to say why no charges were filed. Gonzalez filed a restraining order against Perez, but he could not be located to be served with a copy of the order. A court hearing had been set for Oct. 19, but it was too late by then. The couple was married in January and have a 10-month-old girl who is being cared for by her family. Perez is described in the arrest warrant as being 5-feet, 9-inches tall and weighing 170 pounds. He has black hair and brown eyes. The murder charge and warrant were filed Oct. 15.
