The trial of 25-year-old Andrew Dennehy, charged with shooting into a crowded Tulsa plaza is set to begin.
Dennehy is charged in the March 7, 2012, shooting, in the plaza between the Tulsa County courthouse and Tulsa Central Library that injured a deputy sheriff and a bystander.
Dennehy was also wounded when authorities arrived and returned fire.
Dennehy has pleaded not guilty by reason of insanity.
Dennehy's family and attorney say he's a paranoid schizophrenic plagued by bizarre thoughts and delusions.
Prosecutors say Dennehy is bluffing and understands the charges against him.
