Vital Statistics at Time of Disappearance
Details of Disappearance
Sheila and her younger sister, Katherine, left their Kensington home by themselves to walk to Wheaton Plaza Shopping Center. Witnesses saw Sheila and Katherine talking to a middle-aged man in a brown suit and carrying a briefcase outside the Orange Bowl pizza parlor at about 1 p.m. The man had a microphone and tape recorder, and the two girls were seen speaking into the microphone. The man was never located.
The sisters got a bite of pizza, eating together inside the restaurant, and were spotted walking toward their house between 2:30 and 3 p.m. That was the last confirmed sighting of the Lyon sisters.
An extensive search was conducted after the disappearance of the girls, whose father was a well-known radio host. About two months after the sisters went missing, Maryland's then-governor called the National Guard to search for them in a Montgomery County forest.
