A man who killed four people when he plowed his car into a crowd of pedestrians near UC Santa Barbara in 2001 is due in court Tuesday for a competency hearing to determine if he should be released from a state mental hospital.

David Attias, who was a 20-year-old college student when he drove his turbocharged Saab into the crowd, was convicted of four counts of second-degree murder in June 2002. A week later, the same jury found him legally insane and a judge committed him to Patton State Hospital instead of sending him to prison.

On Tuesday, Attias is to be in Santa Barbara County Superior Court for the start of a four-day hearing to determine if he should continue to be held at the San Bernardino facility. Attias, who had faced at least 50 years in prison, had emotional problems dating to infancy and suffered a psychotic break the night of the rampage, his lawyers argued at the time.

Prosecutors conceded that Attias was mentally ill but contended he knew what he was doing when he sped along streets crowded with weekend party-goers in the college community of Isla Vista. Witnesses described Attias emerging from his car, shouting “I am the angel of death!”
