WASHINGTON - Police are investigating how a man was electrocuted at a D.C. school, early Tuesday morning.
Metropolitan Police say they found a man thought to be in his mid 30's at Wheatley elementary school on Neal Street in Northeast around 2:30 a.m.
Police believe the victim was trying to steal copper wire from the building when he came in contact with a live wire and was electrocuted. Officers also believe the victim had a partner.
According to D.C. Public School's Website, Wheatley was closed this fall as part of the District's reorganization plan.
