Katherine Mary and Sheila Mary Lyon

Last seem in Wheaton, Maryland on May 25, 1975

Vital statistics: Katherine is a white female. She was born on March 29, 1964. Blond hair, blue eyes. She has a birthmark inside her upper thigh. Her nickname is "Kate." Last seen wearing a red jacket, Wrangler brand blue jeans with a front zipper and bell bottoms, dark brown knee socks, dirty beige brushed suede wallaby type Jumping Jack shoes, and a beaded orange bracelet with "Kate" written in black letters on white beads. Was ten at the time. Sheila is a white female. She was born on March 30, 1962. Blond hair, blue eyes. She wears gold wire-rimmed eyeglasses and is farsighted. Last seen wearing a dark blue sweatshirt, orange or gold knee socks, a training bra, wheat-colored corduroy pants, and low-cut white GallenKamp sneakers. Was twelve at the time.

Circumstances: They were last seen inside the Orange Bowl restaurant talking to an unknown middle-aged man on March 25, 1975. They did not return home when they were supposed to, and haven't been heard from since. However, the girls were believed to have been spotted bound and gagged in the rear of a beige Ford station wagon on April 7. The car had the licence plate number DMT-6** (the last two digits are unknown due to the bending of the plate). A picture of the suspect is posted below. Later, this sighting was deemed "unreliable" for undisclosed reasons. This is the last noteworthy tip in the case. A ransom demand was not followed through. Their father, John Lyon, was a well-known radio personality in the area. Classified as Endangered Missing.

Theories: There are two possiblities here. One is that Sheila and Katherine ran away together. However, there is nothing to indicate that is the case, and subsequent information seems to contradict this theory. With that out of the way, abduction seems to be the only other choice. With that, questions arise. Who was the man the girls were speaking to the day they vanished? What would he want with the girls? Why was a demand for ransom made when the girls were observed alive almost two weeks after their intial disappearence? The sighting of them alive also leads one to wonder if this was perhaps the intent all along, and the ransom demand was either not sent by the abductor or a ploy to lure people away from them. Both girls are very attractive, and the thought that another had dark designs for them must not be overlooked. Above all, we must remember that we are looking for two grown women, and not two bodies. In order to find a person, one must seek out a person.
