WASHINGTON (WUSA) -- A reward of $50,000 will be given to the person with information that leads to the arrest and conviction of the person responsible for killing Virginia State Trooper Johnny Rush Bowman in August 1984.

Trooper Bowman was repeatedly stabbed by someone when he opened the door to his Manassas, Va. home on the morning of August 19, 1984. The attacker fled, but left behind eyeglasses, a wig and a construction hard hat.

Bowman's wife was home at the time and called 911. The trooper died shortly after the attack at a local hospital.

You may remember in 2005, that the Virginia State Policelaunched a media campaign asking for the public's assistance in recalling any details that could help to solve this case.

The FBI, Virginia State Police and Manassas City Police have been working since Trooper Bowman's death to identify a suspect, even traveling to California and Ohio to investigate leads from their evidence.

If you have any information, please call the FBI at 1-800-CALL-FBI (1-800-225-5324) or the Virginia State Police tip line at 703-803-2637.
