A California woman was shot dead and a man she was seeing who was already in custody for unrelated crimes is now a suspect in her murder.
On Aug. 16, alleged gang member David Hernandez, 42, is accused of committing a robbery and carjacking at the Cali Smoke Shop in a Fresno shopping center.
“Information from a citizen ... led detectives to the apartment complex … where the [carjack] victim’s vehicle was located,” Fresno police Lt. Bill Dooley reportedly said.
Hernandez then got into a nearly six-hour standoff with the Fresno police SWAT team that evening at the apartment complex, where 41-year-old Sarah Hamm lived. Hernandez surrendered to authorities and Hamm was later discovered fatally shot in her unit, police said, according to KFSN-TV.
Hernandez is being held on suspicion of murder at the Fresno County Jail. Authorities have not released a possible motive for the shooting.
The suspect has a long criminal history and was most recently arrested on July 5 on suspicion of a DUI, driving with a suspended license and battery, The Fresno Bee reported.
Anyone with information regarding the murder should contact the Fresno Police Department or homicide detectives B. Barnes at (559) 621-2421 or M. Alvarez at (559) 621-2441.
