On May 4th, 2006, at around 10:00 PM 60-year-old Security Guard Frutoso Anguiano was on duty at the Northgate Gonzalez Market on 831 Hacienda Boulevard in La Puente, CA. As the store was about to close Anguiano went to the rear of the store and up to a second floor break room where he was met by four Hispanic men. Anguiano was handcuffed and stabbed fifty-two times. Surveillance video shows the four men mingling around the store prior to closing and then disappearing into the back. The video didn’t show the murder but caught the men coming down the stairs wearing masks and holding the gun they had taken from Anguiano. Los Angeles County Sheriff’s Cold Case Detective Shaun McCarthy tells us his working theory on the attack and how DNA might lead him to one of the men who lives in another state.
