Police say the man, identified as 63-year-old Arthur Williams, of Gadsden, Ala., walked into a Turkish men's wear store in Manhattan last Friday with a cane and breathing through a tube connected to the tank. Police say he fired three shots after demanding money, but fled empty-handed. No one was injured.
Officials say Williams made his way to Maryland where he robbed two hotels early Sunday.
A description of the robber went over police airwaves and a state trooper, who was following a drunken driver, realized he was pursuing the robber.
After a 2 1/2-mile chase, authorities say the robber ran off the road and crashed into a parked car. He was pronounced dead at the scene.
