A California man was arrested this week on suspicion of killing his mother over an argument that started while he was playing a video game.

According to WCAU, 28-year-old Matthew Nicholson allegedly became upset with his mother, 68-year-old Lydia Nicholson, on Thursday and shot her in the head after an escalating argument. She died a short time later at an area hospital.

Police were called to the home in Ceres, where they found the victim with a head wound and arrested her son. Reports indicate he blamed her for breaking a headset used with his video game system.

After retreating to his room, Lydia Nicholson reportedly attempted to check on him, resulting in a re-ignition of the earlier argument and another shouting match, police reports indicate.

Matthew Nicholson allegedly fired a handgun twice into a wall before aiming at his mother. After the shooting, the suspect’s 81-year-old father was reportedly able to disarm him.

“It was the father calling to report that the son had shot his wife in the head,” Ceres Police Sgt. Greg Yotsuya said, according to a report by KTXL.

The suspect fled in a vehicle to the home of a family member in Riverbank, where officers spotted his car and stopped him.

He was placed under arrested and booked into Stanislaus County Jail without bail. He is expected to be charged with homicide.

Investigators say the case remains open and urge anyone with information related to the shooting to call Ceres Police Detective Bryan Ferreira at 209-538-5616.
