18-year-old arrested for fatally shooting mother with AR-15 style rifle in Fontana: Police

An 18-year-old man was arrested in Fontana Thursday morning, accused of fatally shooting his mother with an AR-15 style rifle.

Around 1:45 a.m., Fontana Police officers responded to reports of gunshots heard in the 14600 block of Mountain High Drive. While officers responded to the area, they received additional calls of shots fired in the street and a report of a male seen outside holding a rifle. A 12-year-old inside one of the residences phoned 911 to report her family member was shot inside the home.

Officers arrived and found Fabian Dusten Cardona, 18, hiding near the passenger door of a white pickup truck. Cardona was armed with a scoped AR-15 style rifle and aimed the gun in the direction of the officers, according to a press release. An officer fired one round at Cardona missing him. Cardona immediately dropped his rifle and surrendered to the officers, authorities said.

Officers and medics went into the house and located a 50-year-old female suffering from multiple gunshot wounds to her torso. She was transported to an area hospital where she later succumbed to her injuries. Her name has not yet been released.

Authorities said the investigation revealed Cardona is the victim's son. Both lived together at the Fontana home. The preliminary investigation suggests Cardona had shot the victim, exited the residence and banged on at least two unrelated doors of homes. He then fired his rifle at an unoccupied van parked in the street. Cardona then broke into a pickup truck where he appeared to be lying in wait for the officers. Detectives are working to determine a motive to the shooting.

Cardona will be booked into the West Valley Detention Center for homicide. No officers or other members of the public were injured during the incident.
