Authorities responded to a home on River Valley Circle in Ceres around 9:50 p.m. Thursday and found the woman had been shot in the head, according to a statement from Ceres police.
Matthew Nicholson, 28, got in a fight with his mother Lydia Nicholson, 68, and shot her in the head, police said..
Autumn White, the suspect's sister, said, "My mom was a wonderful person who loved her children".
During their investigation, police learned Matthew Nicholson, 28, had been in his bedroom playing video games when he became upset and started yelling. Paramedics followed and took Lydia Nicholson to a hospital, where she would soon die.
According to Ceres Police Sgt. Greg Yotsuya, this was the second call in the last six months regarding domestic disputes between Matthew Nicholson and his parents. "The father grabbed the gun, emptied it". A long-time friend of the family elaborated, telling FOX40, "I understand that he would've killed the father too, but the gun jammed".
Barcelona midfielder, Arda Turan joins Istanbul Basaksehir on loan
Basaksehir confirmed earlier this week that they had agreed personal terms with Turan but that they still had to finalise the deal with Barca.
Lydia Nicholson worked and volunteered in local schools.
He allegedly grabbed a gun and shot his mother before his 81-year-old father wrestled away the firearm. Neighbors say the family is friendly, the murder...surreal.
Nicholson then ran out and began driving to a relative's home in Riverbank, CA. He was later taken into custody there without incident.
Investigators are still working to determine what drove Nicholson to kill his own mother.
Nicholson was booked into the Stanislaus County Jail for homicide where he is being held without bail. "Was it the video game or was there something else going on".
