CHULA VISTA, Calif. (KGTV) - Chula Vista Police identified Tuesday a man and woman who were shot by the woman’s ex-boyfriend in a deadly domestic violence dispute near a Costco.

The incident happened Monday afternoon while Angelina Perez, 32 and Samuel Valdez, 31, were loading groceries in the trunk of their vehicle in the parking lot of the store on Broadway with their infant daughter in a stroller.

Sean Illian, 48, approached them with a gun and opened fire, hitting Perez and Valdez several times, police said. The baby was not hurt.

Witnesses in the parking lot saw Illian shoot himself in the head. He was pronounced dead at the hospital.

Perez and Valdez were taken to UC San Diego Medical Center in critical condition.

Police said Perez and Illian had been in a relationship which ended badly in 2018. Perez began dating Valdez just after the breakup, investigators said. Officers believe Perez’ new relationship was the motive for the shooting.

The victims’ daughter is in the care of relatives.
