The Montgomery County Police Department Cold Case Squad and FBI agents in the Baltimore Division have named a person of interest in the disappearance of sisters Sheila and Katherine Lyon from a popular suburban Washington, D.C. shopping center in 1975. Investigators say Lloyd Lee Welch, (date of birth December 30, 1956), aka Michael Welch, pictured below, was noticed paying attention to the sisters the afternoon they disappeared.


Sheila and Katherine, pictured below, were last seen just after 2 p.m., walking between Wheaton Plaza (now Westfield Wheaton) and their home, only half a mile away. Their mother told them to be home by 4 that afternoon, but they never returned. They disappeared without a trace and have not been heard from since.


Welch, a convicted sex offender, has been in prison in Delaware since 1997. He traveled extensively throughout the U.S. from the 70s through the mid-90s. Welch worked as a ride operator for a carnival company, often set up at malls. He was arrested in several states on charges of sexual offenses against young girls. There may be victims who have not come forward.

“We understand we’re asking people to think back several decades to remember details they may not think matter. However, the information you provide could be vital in our search for evidence and put to rest difficult questions for the Lyon family and for any other victims who may exist,” said Steve Vogt, Special Agent in Charge of the FBI in Maryland.

“We have all been haunted by the disappearance of the Lyon sisters. Even though so much time has passed, we have not forgotten that those young girls deserve justice, and their family deserves closure. We’re hoping one of you has information that will help us provide both,” said Montgomery County Police Chief Thomas Manger.
