The Washington Navy Yard gunman Aaron Alexis played violent video games including Call of Duty for up to 16 hours at a time and friends believe it could have pushed him towards becoming a mass murderer.
Alexis, 34, who was shot dead on Monday after killing 13 people at Washington’s Navy Yard, also carried a .45 handgun tucked in his trousers with no holster “everywhere he went” because he believed people would try to steal his belongings.
He also felt racially discriminated against, and believed he had been financially “screwed” over a contracting job in Japan at the end of last year, friends said.
The addiction to violent video games and guns was at odds with his devout commitment to Buddhism, which saw Alexis spending half the day every Sunday meditating at the Wat Busayadhammvanaram temple in Fort Worth, Texas over a period of several years. He also spent a month in Thailand in April, The Daily Telegraph can disclose.
