The suspected “lone-wolf” shooter of the Batman movie theater massacre in Aurora, Colo., earlier today has been identified as Ph.D. student James Holmes, who recently withdrew from his neuroscience studies at the University of Colorado before shooting up “The Dark Knight Rises” screening.

Holmes, 24, moved to Aurora to pursue his Ph.D. at the University of Colorado medical center, living just blocks from the hospital in an apartment that is now laced with explosives and being searched by HazMat teams.

Holmes killed at least 12 people and injured as many as 50, including U.S. military members, during the midnight premiere of the movie at the Century 16 Movie Theaters in Aurora early this morning. He barged into the theater mid-show, setting off smoke bombs and stalking up and down the aisles firing as many as four weapons at viewers.
