A University City man accused of killing his father was committed to Patton State Hospital last week after a judge ruled he was not mentally competent to stand trial. Nikola Chivatchev, 25, did not have the mental capacity to make a decision about taking anti-psychotic medication that he needed to take for his mental disorder, ruled San Diego Superior Court Judge Howard Shore after he read psychiatric evaluations of Chivatchev. Chivatchev is accused of using a 12-pound dumbbell to hit his father, Alexander Chivatchev, 64, in the head while he was asleep at 1:15 a.m. on Oct. 7, 2009. Police responded to a frantic 911 call by the victim’s wife to their home in the La Jolla Crossroads apartment complex in the 9100 block of Judicial Drive. Chivatchev was arrested and charged with his father’s murder. His attorney told a judge on April 7 his client didn’t have the mental capacity to understand court proceedings. Criminal proceedings remain suspended against Chivatchev, but if he regains his mental competency, he will be returned to San Diego to face trial. Chivatchev, who is from Bulgaria, has already spent 281 days in jail. — Neal Putnam
