Officers responded to the scene a little before 10 p.m.to investigate, and found a 68-year-old woman who had been shot in the head.
Investigators say the shooting stemmed from an incident involving a broken video game headset.
According to a report from the Ceres Police Department, 28-year-old Matthew Nicholson was playing video games in his room on Thursday night when he got upset and started yelling. "The father grabbed the gun, emptied it".
Loren Nicholson then called the police, at around 9:50 pm, to report the crime and call for medical attention for his wife.
Lydia Nicholson was transported to a hospital for treatment but ultimately succumbed to her injuries.
A fourth bullet struck his mother in the head and killed her.
Lydia worked and volunteered in local schools.

It's always important to read medicine labeling, too - even if it's not obtained by prescription. But health officials say that shouldn't be a problem as most coughs don't need any treatment.
Matthew Nicholson's sister Autumn White paid tribute to their mother and wrote, "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".
Police say he grabbed a nearby handgun that was in the Nicholson home and shot two rounds into the wall, then shot his mother in the head.
Neighbors said the family was friendly.
"What's this world coming to, a video game, 28 year old kid with his video game. Speechless", said Ron Kutzman, a neighbor of the Nicholson family.
Officers tracked the vehicle to the relative's home and took Nicholson into custody.
Investigators are still working to determine what drove this man to kill his own mother.
Nicholson is facing murder charges and is being held at the Stanislaus County Jail.
