Former congressional staffer Walter Graham was found strangled to death in his Mount Vernon-area apartment more than 20 years ago, and his killing remains a mystery.
Graham's case is one of thousands of unsolved homicides in the D.C. area, and Fairfax County Police are still seeking any bit of information that can help find the killer.
At one time, the FBI suspected Graham may have been a victim of a serial killer from the D.C. area, but that theory has faded.
Graham, who worked for former Rep. Delbert Latta, R-Ohio, for nearly 10 years, was found strangled on Aug. 10, 1991. He was 59.
Officers found his body in the living room of his Riverside Park apartment complex at 2000 Huntington Ave. after friends called police saying they had not heard from Graham in several days.
The place had been ransacked.
There was no indication of forced entry into Graham's 14th-floor apartment. A chain-link fence surrounded the high-rise, and a magnetic pass was needed to get into the building.
Graham, a gourmet cook and avid pianist, was originally from Philadelphia. He had worked on the Hill for more than 20 years.
Three years after his death, as the FBI started a manhunt for serial killer Gary Ray Bowles, police in Virginia suspected that Graham could have been one of his victims.
Bowles, nicknamed the "I-95 Killer" because his victims lived along the Interstate 95 corridor from Maryland to Florida, was wanted for the slayings of six other men over four months.
Bowles was arrested in 1994. He reportedly confessed to the six killings, but denied killing Graham.
Police are hoping that someone will come forward with information that can help solve Graham's killing.
