Alabama ? The gunman who killed 10 people and committed suicide in a rampage across the Alabama countryside had struggled to keep a job and left behind lists of employers and co-workers he believed had wronged him, authorities said Wednesday.

The lists found in Michael McLendon’s home included a metals plant that had forced him to resign years ago and where he ended up killing himself Tuesday to end the rampage, District Attorney Gary McAliley said. Also on the list were a sausage factory from which he suddenly quit last week and a poultry plant that suspended his mother, McAliley said.

The pages torn from a spiral notebook included names of co-workers who he felt had wronged him, including one who reported him for not wearing ear plugs, another who made him clean a meat grinder and a supervisor who didn’t like the way he cut pork chops, McAliley said.
