A Marin County judge ruled there is sufficient evidence to hold a Marin City matricide suspect for trial.

Carlos Aldana, 24, is charged with stabbing Rosa Aldana, 44, dozens of times Aug. 23 at her apartment on Cole Drive. He is also accused of fatally stabbing a pit bull belonging to his mother's boyfriend.

A short time later, he allegedly boarded a Golden Gate Transit bus soaked in blood and carrying a knife. Police confronted him after he got off the bus in San Francisco, then shot him after he allegedly threatened officers with the knife.

Legal proceedings were repeatedly delayed while Aldana was hospitalized for mental health issues and an infection related to the gunshot injuries.

After a preliminary examination of the evidence that began last week, Judge Kelly Simmons ruled Tuesday there is enough evidence to justify a trial. In addition to the blood and weapon evidence, Simmons noted that the suspect had recently called his mother "the devil," had been carrying a knife around for several days prior to the slaying, and was upset over money and his living arrangements.

Aldana, who is being represented by the public defender's office, was ordered to return to court June 17 for further proceedings. He is being held without bail.
