Aaron Alexis lived for a time in a bungalow in the woods near a Buddhist temple in Fort Worth, Texas, where he occasionally joined Thai immigrants in meditation. Aaron Alexis died Monday in a gun battle with police in a building at the Washington Navy Yard after he killed at least 12 people. In between, the man named as the shooter in Monday's mass murder at Navy Yard Building 197 was discharged from the Navy Reserve, arrested for shooting a bullet into his downstairs neighbor's apartment and then asked to leave his Fort Worth apartment.
