US: Walmart shooter left 'death note', bought gun the day of killing

The Walmart supervisor who shot six co-workers to death at a store in Virginia bought the gun just hours before the killings and left a note on his phone accusing co-workers of mocking him, authorities said Friday. "Sorry everyone but I did not plan this I promise things just fell in place like I was led by the Satan," Andre Bing wrote on a note that was left on his phone, the Chesapeake Police Department said Friday.
