Federal, state and local authorities have announced a $50,000 reward for information leading to an arrest and conviction in the 1984 murder of a Virginia State trooper.

On Aug. 19, 1984, Trooper Johnny Rush Bowman answered the front door of his Manassas home and was stabbed repeatedly. The suspect or suspects fled on foot and left behind eyeglasses, a wig and a construction hard hat, authorities said. Shortly after the attack, Bowman died at a hospital, leaving behind his wife and 2-year-old daughter.

"It is important for the public to know that no piece of information is too small to share. With the assistance of advanced forensic science, we are able to actively pursue new leads to identify whoever is responsible for this murder," James W. McJunkin, Assistant Director in Charge of the FBI's Washington Field Office, said in a news release.

The FBI, Virginia State Police and Manassas City police are all investigating the incident.

Anyone with information can call the FBI at 1-800-CALL-FBI (1-800-225-5324) or the Virginia State Police tip line at 703-803-2637.
