Paige Nicole Chiarello, 20, of Redondo Beach, California, was shot in the head during a domestic dispute at her grandfather’s home on Graham Avenue on August 12, 2015. Redondo Beach police got a shots-fired call about 1:30 p.m. Officers surrounded the house and negotiated with the suspected shooter, identified as Paige’s boyfriend and the father of her 8-month-old child, Roy Peña Rodriguez Jr. Rodriguez surrendered to police just before 2 p.m.

Paramedics found Paige with a critical gunshot wound; she was taken to a local hospital and was pronounced dead the following morning at 3:25 a.m. The investigation determined the shooting began as a domestic dispute and that Rodriguez allegedly shot Paige and threatened her grandfather when he intervened and called 911, which prompted the police response. Rodriguez was arrested and charged; after Paige’s death the charge was upgraded to murder, with additional counts including dissuading a witness by force and making criminal threats.
