Tustin Police Arrest Man Accused of Killing Ex-Girlfriend and Fleeing to Mexico
Tustin police have arrested Juan Marquez, a 47-year-old man, in connection with the fatal shooting of his ex-girlfriend, Sandra Fernandez, aged 42. The incident occurred last Thursday when Fernandez was found unresponsive with gunshot wounds at the intersection of Yorba Street and Medford Avenue in Anaheim. She was pronounced dead at the scene. Marquez, a resident of Hawthorne, allegedly waited for Fernandez near her workplace before the shooting. Following the incident, Marquez fled across the U.S.-Mexico border at the San Ysidro Port of Entry. Authorities obtained an arrest warrant, and U.S. Customs and Border Protection detained Marquez as he attempted to return to the U.S. He was subsequently taken into custody by Tustin detectives and booked into the Orange County Jail on a murder charge, where he is being held without bail.
