A Walmart shooter who pulled out a weapon and killed six people in a store had written a manifesto where he outlined how he was unhappy in his work, it is reported.
Andre Bing, 31, a Walmart manager, fired wildly around a room at a Virginia shop ahead of a routine employee meeting just after 10pm on Tuesday night.
The gunman was an overnight team leader who had been a Walmart employee since 2010. Police said he had one handgun and several magazines of ammunition.
