The man accused of killing his mother over the weekend in Oceanside was arraigned Wednesday and is being held in jail without bail.
Anthony Sardina, 37, looked emotionless in court as the charges against him were detailed.
He's accused of using a knife to kill his 64-year-old mother, Regina Sardina, in a home she owned in Oceanside on Sunday.
Police say Regina was discovered by one of her three sons at around 12:30 p.m. and the Oceanside Police Department was called
Regina was supposed to meet another one of her sons in Las Vegas, but when she didn't show another son came to check on her and found her, according to OPD Sgt. Bussey.
When officers arrived at the home they discovered her Mercedes was missing. It was found a short time later abandoned in the parking lot of a nearby Hobby Lobby.
Investigators found a wine bottle and vomit near the car, and said surveillance cameras caught Anthony, Regina's oldest son, leaving the car.
A witness told police he saw a man near the car who appeared very drunk.
According to police, Anthony caught a cab to Carlsbad where he was later arrested.
Anthony looked rather emotionless in court Wednesday and occasionally looked up at family members who were in court.
Neighbors told NBC 7 Tuesday that Regina lived in Las Vegas but would often visit San Diego. They also said the house she was found in was recently put up for sale and that her sons have been staying there.
"I can't make sense of that because I just can't and imagine that, personally, a son hurting his mother," neighbor Greg Holmes said.
Other neighbors told NBC 7 they've heard some family bickering in the past but nothing that signaled violence.
Anthony is being charged with murder and could face 51 years to life in prison if convicted.
