A truck driver gave a panhandler $1, then struck and killed the man as he drove his rig away. Police said it was possible the driver didn't know what happened.
Michael Burns, 43, who had no known address, was standing near an interstate ramp Thursday and holding a cardboard sign: "Homeless. Need Help. God Bless."
Witnesses and police said a trucker who was stopped for a red light gave a dollar to Burns. As the truck started making a left turn, its trailer knocked Burns down, and two sets of the truck's tires ran over him.
The truck had no identifiable markings, and witnesses weren't able to get a tag number.
Officer Randall Ward said it appears to be an accident. "A dollar cost him his life," he said.
