An Antelope man convicted Wednesday in Sacramento Superior Court of killing his mother at their home in 2014 faces the possibility of life in prison.
John David Matta, 54, faces 25 years to life in prison when he is sentenced Nov. 17 in Sacramento Superior Court. Jurors found Matta guilty of first-degree murder at trial before Judge David Abbott.
Matta, who Sacramento County district attorney’s prosecutors said had a history of elder abuse, lived with his mother Janet in their home when he attacked her May 18, 2014, beating and choking her to death.
The Bee reported at the time that Sacramento County sheriff’s dispatchers received a call from a home in the 8000 block of Silk Tree Way in Antelope about 4:45 p.m. May 18, 2014. A man told dispatchers he had an altercation with his mother before the phone call was disconnected.
Deputies arrived to find Janet Matta dead inside the home. Medical examiners later determined she died from blunt force trauma and asphyxiation.
