Maine's congressional delegation is calling for the Army to investigate the events that lead up to the October mass shooting - the deadliest in the state's history - by one of its reservists.
Robert Card killed 18 people in a bowling alley and a restaurant in Lewiston on Oct. 25, authorities said, and his body was found - with a self-inflicted gunshot wound - two days later. Reports soon began to emerge that the 40-year-old Card had spent two weeks in a psychiatric hospital and at roughly the same time was amassing weapons.
