It happened Friday night in Ceres.
28 year old Matthew Nicholson is now in custody after allegedly shooting, and killing, his mother over a broken gaming headset following a heated argument that led to he himself breaking it.
It ended with the death of his mother, Lydia, according to investigators.
The 68-year-old woman later died at a hospital from her injuries.
She was shot in the head after an argument erupted when she came to his room to check on him. During the exchange, reports state that he broke his own headset and then blamed Lydia for the damage which escalated the fight to an ultimately fatal level.
During the argument, Nicholson grabbed a gun and started shooting, police told KCRA 3 News.
At some point, Nicholson got a handgun and shot two rounds into the wall then another shot at his mother, investigators say.
Police located the 28-year-old's auto in Riverbank and took him into custody without further incident.
"I will forever love you, my best friend, my chosen one, my always, my forever my protector, my motivation, my blessing, and now my guardian angel". A fourth struck his mother in the head, killing her.
KCRA 3 News reports Lydia was active in the community and volunteered in local schools. Neighbors say the family is friendly, and they are shocked by her murder.
Nicholson fled to a relative's house in Riverbank after his father wrestled the gun from him. "Speechless", said Ron Kutzman, a neighbor of the Nicholson family.
Ceres police took Nicholas to the police department for questioning then later booked him into the Stanislaus County Jail where he's being held without bail.
