The case of Katherine and Sheila Lyon’s disappearance has been an unsolved mystery of over 50 years. The two sisters went out together on a seemingly normal day in March of 1975, never to return. No one knows exactly what happened to them that fateful day, yet new evidence has surfaced by the police in Maryland that has sparked hope we may eventually have an answer regarding the two sisters’ fate.
The sisters disappeared after a trip for pizza

During their school holiday in 1975, Katherine and Sheila Lyon were about to celebrate their 11th and 13th birthdays. The two sisters decided to go out together for pizza near Wheaton Plaza, Maryland on a March day. When they didn’t come back by their curfew, their mom started panicking.
The frantic search began with no answers in sight

Mary Lyon called 9-1-1 after a few hours, which sparked a huge investigation in the Washington, DC area. Planes, dogs, and volunteers were involved in the search, but sadly, the officials couldn’t find any answers for the sisters’ family and friends.
The case went cold for over four decades

The case stayed unsolved for 42 years — until 2017, when Lloyd Lee Welch Jr. was finally convicted for kidnapping and killing Katherine and Sheila.
A long-forgotten file provided a vital clue

Chris Homrock, the deputy sergeant from the Montgomery County Police, was going through some files when he found a 1975 document he’d never seen before. The suspicious document was about an 18-year-old named Welch, and the picture in it looked a lot like a drawing of someone who was said to have leered at the sisters back in 1975.
The suspect had a dark and violent history

Upon further investigation, Homrock discovered that Welch was already in prison for molesting a 10-year-old girl in 1998. He was serving a 33-year sentence for a serious criminal record, including domestic violence, rape, and assault with a knife.
Welch confessed during a confrontation with police

Homrock went to visit Welch, and the prisoner immediately said, “I know why you’re here. You’re here about those two missing kids.”
The court handed Welch a life sentence

On September 12, 2017, Welch admitted to the abduction and murder of Katherine and Sheila, pleading guilty to two charges of first-degree murder. The court gave him two concurrent 48-year sentences. He will spend the rest of his life in prison. Once he finishes his original term in Delaware in 2026, he’ll be transferred to a Virginia facility to complete the rest.
The girls’ remains have never been found

Katherine and Sheila’s remains have still never been found. Even after all these years, nobody knows where they are, and that part of the case remains a big mystery. The family and police still don’t have any answers about what exactly happened to them.
New evidence was found at Taylor’s Mountain

Last week, the US Marshals Service confirmed that they found “new evidence” related to a cold case in Taylor’s Mountain, Virginia, the area that has long been linked to the girls’ disappearance. But the local authorities didn’t say exactly what the evidence was or which case it might be connected to.
The case continues to haunt investigators and the community

The story of Katherine and Sheila Lyon still lingers in people’s hearts. Even though Lloyd Welch was convicted, their bodies have never been found. It feels like the case isn’t fully closed, and it continues to haunt those who remember what happened to those two girls.
