Germany grapples with enigma of Munich gunman

Investigators were seeking clues Sunday into the mind of gunman David Ali Sonboly, the teen author of one of Germany's bloodiest killing sprees. Sonboly's rampage at a Munich shopping mall on Friday sparked a terror alert, with fears that Germany had followed France and Belgium this year in becoming targets of the Islamic State (IS) group. Thirty-five others were injured, 11 of them seriously, according to a new toll released by Munich police Sunday.
