McInerney is charged with shooting and killing his classmate, 15-year-old Lawrence King, at E.O. Green School in Oxnard in February 2008.
McInerney, who's being tried as an adult, also faces hate crime charges because the victim was openly gay.
McInerney's father, William, was found dead at home on March 18.
His death has been ruled an accident, with alcoholism as a contributing factor.
