The gunman who killed six at a Sikh temple in Oak Creek, Wis., on Sunday struggled with alcohol, according to investigators. Wade Michael Page was booted from the Army in 1998 for showing up intoxicated to military exercises. A year later he was cited for drunk driving in Colorado. Page worked as a truck driver from 2006 to 2010, when the company fired him after he was charged with driving while impaired in North Carolina. After losing his job, Page fell into financial trouble and wasn’t able to keep up with the mortgage payments on his house. He was foreclosed on in January.
