The court was told Baumgartner had joked with a friend about robbing his employer and had sent a text that said: "This is the night." The court also heard that Baumgartner owed friends money, had just bought a new truck and had argued with his mother about rent before his last shift.
Search warrants revealed that his mother told officers she woke up the morning of the shooting to find $64,000 in cash in her home.
After his arrest, Baumgartner initially told police he had been kidnapped after the robbery and forced to drive to Seattle or his family would be killed.
G4S President Jean Taillon said last year that the company was reviewing how it screens its employees, though no policy changes have been made.
Before the heist, Baumgartner had posted quotes on his Facebook page from the character the Joker from the movie "Dark Knight," which included a violent bank heist. The profile picture on the Facebook page showed a person wearing sunglasses and a mask.
Two weeks before the shooting, the page also had a post that mused: "I wonder if I'd make the six o'clock news if I just starting popping people off.
