Police say Christopher Schneider, 31, stabbed his mother Nancy, 66, to death and then stabbed himself after an argument turned violent.
Authorities were called to a home in the 900 block of Woodlawn Drive on Feb. 4. They found a woman unresponsive who had been stabbed multiple times. They also found a man with stab wounds.
They were both brought to a local hospital, where Nancy Schneider was later pronounced dead. Christopher was treated for wounds which investigators later determined had been self-inflicted.
Detectives arrested Schneider on Feb. 9 and he was being held on $3 million bail. His first appearance in Ventura County Superior Court is expected on Tuesday.
