Federal, state and local law enforcement are hopeful that advancements in forensic technology can shed new light on the 30-year-old unsolved murder of Virginia State Police Trooper Johnny Rush Bowman.

Testing performed by the FBI Laboratory on forensic evidence originally submitted in 1984, was retested in the late 1990s and, most recently, in 2010. As a result of the latest testing by the FBI, new information regarding DNA found at the scene has generated extra information for investigators.

In the early morning hours of Aug. 19, 1984, Trooper Bowman answered the front door of his residence in the Bristoe Station development of Manassas, Va., and was repeatedly stabbed by an unknown assailant(s). Trooper Bowmanís wife was present during the attack and placed the 911 call for assistance. The attacker(s) fled on foot from the Bowman residence, leaving behind eyeglasses, a wig, and a construction hard hat. Trooper Bowman, 31, died shortly thereafter at a local hospital. In addition to his wife, Trooper Bowman left behind a 2-year-old daughter.

The crime has had some odd twists. In 1986, it was revealed that authorities had focused on another member of the state police, a close friend of Bowman's named Perry L. Worrell. Worrell was put on administrative leave and left the agency shortly after Bowman's death.

In 2006, a Fairfax County man was accused of threatening a special agent investigating Bowman's death after members of the task force contacted the man's son-in-law.
