MANASSAS, Va. (WJLA) - Thirty years after the murder of a Virginia State trooper inside his Manassas home, there's hope new technology can lead to his killer.
Trooper Johnny Bowman, 31, was stabbed more than 40 times, after answering his door on August 19, 1984.
Bowman's brother Mark and a daughter are the only surviving family members.
"I would love to look at the face that is responsible," Mark Bowman says.
Trooper Bowman's wife saw the attack in the foyer of the house and rushed to call 911. A moment later the suspect turned and ran leaving behind a wig, construction hardhat and eyeglasses.
Despite the evidence, investigators never made an arrest. Since advances in forensic science have not led to the killer, investigators are making an appeal.
Virginia State Police Special Agent Michael Elliott has worked the case for years. Despite following every lead he has never come up with a motive for the killing.

For three decades, all leads have been dead ends. But Bowman's brother is not giving up hope.
"I would like to see the case solved in my lifetime and see whoever has had 30 years of free reign brought to justice and pay for the crime that they did," Mark Bowman says.
Anyone who might have information is encouraged to contact police. A $50,000 reward has been offered.
