Robert Card, the gunman responsible for the deadly shooting rampage in Lewiston, Maine last week, had exhibited erratic behavior three months prior to the attack, prompting the Army Reserve unit to conduct a medical evaluation and deem him "non-deployable due to concerns over his well-being." Local deputies attempted to make contact with Card in mid-September, but were unsuccessful, and the investigation is now shifting away from an intense manhunt and toward the search for a motive.
