CANTON, S.D. (AP) -
Canton's police chief says a homemade bomb left on the back step of a trailer didn't go off because of a flaw in the design.
Chief David Miller tells the Argus Leader that it appears to be an isolated incident meant for one individual, but he declined to discuss further details.
The investigation has been turned over to the Federal Bureau of Alcohol, Tobacco and Firearms.
Harley Ellis says he found the device with jugs of gasoline and gunpowder connected to battery wires and a timer about 8 a.m. Sunday.
When he saw the timer wasn't moving, he thought about picking it up and throwing it away, but decided to call police.
He says he doesn't know who left the bomb and has had trouble sleeping since.
