Montgomery County police say they’ve made a major break in a one the D.C.-area’s most notorious cold case mysteries.

Police said they’ve identified a person of interest in the 1975 vanishing of 12-year-old Sheila Lyon and 10-year-old Katherine Lyon, the daughters of well-known radio host on WMAL.

The disappearance of the young blond-haired, blue-eyed girls gripped the Washington region, leading to one of the most expansive police investigations in the area’s history and puzzling detectives for decades.

Investigators now believe they’ve hit upon a significant breakthrough. A man, whose name was not released, is believed to have been at the Wheaton Plaza Shopping Center on the day the girls disappeared. He is imprisoned in another state.

Montgomery County Police Chief J. Thomas Manger and Special Agent in Charge of the FBI in Maryland Steve Vogt will make the announcement at a news conference Tuesday. They are expected to release more information and photographs, and are seeking the public’s help to learn more about the man and his activities during that time.

On the day the sisters went missing, March 25, 1975, Sheila and Katherine walked the half-mile from their Kensington home to the Wheaton shopping mall. They told their mother they were planning to see the Easter exhibits at the shopping center and have lunch at the Orange Bowl restaurant.

Witnesses spotted the girls talking to a middle-aged man who was wearing a brown suit and carrying a briefcase outside the restaurant.

The girls were spotted speaking into a microphone attached to a tape recorder that the man was carrying.

Later in the day, the sisters were seen walking toward their house. That was the last confirmed sighting of the young sisters. They never returned home.
