HARRISBURG, Pa. (AP) _ Three convicted murderers are scheduled to be the first inmates to die in Pennsylvania's electric chair in nearly a quarter-century.

Gov. Dick Thornburgh on Thursday signed the death warrants for what would be the first executions since 1962, when Elmo Smith became the 350th person to die in the state's electric chair.

The inmates who received warrants were Keith Zettlemoyer, 30, of Snyder County; John Lesko, 26, of Pittsburgh; and Michael J. Travaglia, 26, of Westmoreland County.

The executions of Travaglia and Lesko were scheduled for the week of Nov. 18. Zettlemoyer was scheduled to die the week of Dec. 2.

Fifty-six state prison inmates are on death row, said Department of Corrections spokesman Kenneth Robinson.

The U.S. Supreme Court allowed states to restore the death penalty in 1976; the Pennsylvania statute dates to 1978.
