A U.S. Navy veteran accused of killing two people and critically injuring another in a series of attacks in the Atlanta area had, shortly before the shootings, stormed out of his communal house after getting into an intense argument over the air conditioning in the home, according to his roommates.
Authorities have not offered a potential motive for Monday morning's attacks. Among the victims was an auditor for the Department of Homeland Security who was walking her dog near the suspect's home.
