Convicted murderer James William Hamblen, who once said he thought it would be "spiffy" to die in Florida's electric chair, was electrocuted Friday.

Hamblen, 61, was pronounced dead at 7:12 a.m. at Florida State Prison for killing a Jacksonville businesswoman, the governor's office said.The U.S. Supreme Court, by 7-1 vote late Thursday, upheld a federal appeals court ruling letting the execution proceed. The sole dissenter was Justice Thurgood Marshall, who objects to use of capital punishment in all cases.

Hamblen became the 140th person nationally and 24th in Florida to be executed since the 1976 Supreme Court ruling letting states resume use of the death penalty.

Hamblen was condemned for the April 24, 1984, slaying of Laureen Jean Edwards, the owner of a Jacksonville lingerie shop, the Sensuous Woman, during an attempted robbery.
