  • Details of Disappearance
    Katherine and her older sister, Sheila, 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.
