The Colorado massacre suspect Pictures James Eagan Holmes attended high school in the northern suburbs of San Diego. He participated in sports but was described by one person who knew him back then as intensely shy. Holmes is the suspect in a mass shooting early July 20 in a movie theater in Aurora, Colorado. Twelve people died in the initial rampage, and some 58 were injured, most of them from gunshot. There has been no clear motive yet for the alleged actions by the 24-year-old.
