WALDORF — Forty-eight years after Frank Moore was found dead on a construction site along Route 301, the Charles County Sheriff’s Office is again asking the public for the tip that could close the county’s oldest unsolved homicide.
The sheriff’s office renewed its appeal on the anniversary of Moore’s death in a “Pursuit of Justice” cold case post. The post did not announce any new developments in the case.
At about 10 a.m. Nov. 5, 1978, residents called the sheriff’s office about an unresponsive man on a construction site off the southbound lanes of Route 301, according to the post. The property is now the site of the Charleston Senior Community in Waldorf.
Officers found the man with trauma to his upper body. He was identified as Frank Moore, a resident of Washington, D.C., and the state medical examiner ruled his death a homicide. In earlier appeals, the sheriff’s office said Moore was 28 when he was killed, the Chronicle reported in 2022.
The sheriff’s office has not publicly identified a suspect or said what led to Moore being on the site.
One of many open files
Moore’s case is handled by the sheriff’s office’s Cold Case Unit, which revisits homicides, rapes and other serious crimes that have gone unsolved and no longer produce new leads. The office regularly posts anniversary appeals in its “Pursuit of Justice” series.
This year, the Chronicle has covered appeals in the 1987 killing of La Plata mother Juanita Rollins and the unidentified man killed by a vehicle on Crain Highway in 1983. Some old cases have been solved: in 2023, detectives made an arrest in a 44-year-old rape and homicide, WTOP reported.
