A defense lawyer says a man charged in a shooting that sent holiday shoppers fleeing a busy Long Island mall has psychological troubles and has been "in a state of shock" since the episode.

Oliver Lee had a court date Monday on robbery and other charges stemming from the Dec. 22 episode at the Roosevelt Field mall. The 21-year-old has pleaded not guilty.

His lawyer, Anthony Colleluori (cahl-uh-LOHR'-ee), suggested outside court that he might mount a psychological defense. He says Lee is "very confused" and has been through traumas Colleluori wouldn't detail.

Police say Lee asked to see an $18,000 Rolex watch at a Tourneau store at the mall, then flashed a gun, which went off as he struggled with a security guard. A bystander was shot in the shoulder.
