TUSTIN, California The shooter who went on a violent rampage in California earlier this week has been described by authorities as a "loner" and a "gamer," CBS LA reports. The Orange Country sheriff's department has been investigating 20-year-old suspect Ali Syed since he allegedly shot five people, three fatally, before turning the gun on himself.
"He spent a lot of time alone in his room playing video games," said Orange County Sheriff's department spokesman Jim Amormino.
There is still no known motive in the case and law enforcement officials are now trying to determine whether Syed, an unemployed part-time college student, was under the influence of drugs or alcohol.
The first victim in Tuesday's shooting spree was identified as 20-year-old Courtney Aoki. She was shot multiple times around 4:30 a.m. in Syed's home. The relationship between Aoki and Syed is still unknown.
After allegedly killing Aoki, Syed fled the home he shared with his parents in an SUV.
His mother, Sarwat Syed, called 911 after hearing shots downstairs from her third floor bedroom.
The Orange County Sheriff's Department released a recording of that phone call in which a frantic Sarwat told the dispatcher that someone was in the house.
Syed reportedly carjacked a number of vehicles across the cities of Orange, Tustin and Villa Park after he left his parents' home.
Authorities said he shot and killed two people and injured at least three more before turning the gun on himself. Sheriff's department spokesman Jim Amormino said an autopsy confirmed Syed died of a self-inflicted gunshot wound to the head. The gun belonged to Syed and was purchased by his father a year ago.
Syed's family is heartbroken by the situation, according to family attorney Vincent John LaBarbera Jr.
"Their thoughts and prayers go out to the families of all the victims," he said. "They will continue to assist authorities in the investigation as they themselves try to make sense of this tragedy. The Syed family has much to overcome in the months ahead and we ask that you respect their privacy at this time of tremendous sorrow."
Earlier this week, another grisly crime was linked to gaming when authorities told CBS News correspondent Bob Orr they believe Adam Lanza may have been acting out fantasies from a video shooting game when he killed 26 people at the Sandy Hook Elementary School last December.
