TAMPA, Fla. (AP) - A Bradenton man has pleaded guilty to a federal charge after admitting he tried to kill someone with a car bomb in downtown Tampa.

John Nicholas Coors entered his guilty plea in federal court Monday to use of interstate commerce facilities in the commission of murder for hire, a charge which carries up to 10 years in federal prison.

In August 2009, a confidential source contacted the FBI and described himself as a former acquaintance of Coors, warning that Coors was dangerous. The FBI set up a sting, and authorities arrested Coors when he tried to detonate an improvised explosives device he had placed in a victim's car.

The dynamite - which had been furnished by the FBI - was fake.
