The Disappearance of the Lyon Sisters
Sheila Mary Lyon and Katherine Mary Lyon
On a warm spring afternoon in 1975, two sisters left their home in suburban Maryland for a short walk to the local mall. It was supposed to be a simple outing during Easter break from school. They planned to look at holiday displays, eat pizza, and then return home before dinner.
They never made it back.
The disappearance of Sheila Mary Lyon, age 12, and Katherine “Kate” Lyon, age 10, became one of the most infamous missing children cases in American history. For nearly forty years, the case remained a haunting mystery with no arrests and no answers. Their story deeply affected families across the United States and helped change the way law enforcement handled missing children investigations.
The Lyon Family
Sheila and Katherine Lyon lived with their parents and siblings in Kensington, Maryland, a quiet suburb just outside Washington, D.C. The family home was located on Plyers Mill Road.
Sheila, the older of the two girls, was twelve years old at the time of her disappearance. She was described as a bright, responsible girl with blonde hair and blue eyes. Sheila wore glasses with gold wire rims because she was farsighted. Friends described her as mature for her age and protective of her younger sister.
Katherine, known to family and friends as “Kate,” was ten years old. Like her sister, she had blonde hair and blue eyes. She was slightly smaller than Sheila, standing about 4 feet 8 inches tall and weighing around 85 pounds. Kate was energetic, cheerful, and known for her warm personality.
The sisters were very close and often spent time together walking around their neighborhood and nearby shopping areas.
On March 25, 1975, they made plans for a short trip to the mall.
The Trip to Wheaton Plaza
March 25, 1975 was the first day of Easter vacation for the girls. Around late morning, sometime between 11:00 a.m. and noon, Sheila and Katherine left their home and began walking to Wheaton Plaza Shopping Center in nearby Wheaton, Maryland.
The mall was only about half a mile from their house, a distance the girls had walked before.
They wanted to see the Easter displays set up in the mall and planned to have lunch at The Orange Bowl Restaurant, a popular spot inside the shopping center known for its pizza and casual meals.
Their mother told the girls they needed to be home by 4:00 p.m.
It seemed like an ordinary afternoon.
The Last Confirmed Sightings
The sisters spent several hours at the mall.
At around 2:00 p.m., their fifteen-year-old brother happened to see them inside The Orange Bowl Restaurant eating pizza together. The encounter was brief, but it confirmed the girls were safe and enjoying their outing.
Later that afternoon, between approximately 2:30 and 3:30 p.m., a friend reported seeing Sheila and Katherine walking along Drumm Avenue near Devon Street. The street was part of one of the most direct walking routes back to their home on Plyers Mill Road.
This sighting would become the last confirmed time anyone saw the Lyon sisters alive.
When the Girls Didn’t Come Home
When 4:00 p.m. passed and the girls had not returned, their mother initially assumed they had lost track of time at the mall.
But by 7:00 p.m., hours after they were expected home, the family knew something was terribly wrong.
Police were called, and what followed was a massive search across Montgomery County.
Officers canvassed the neighborhood, the mall, and surrounding roads. Volunteers joined the search, distributing flyers and questioning witnesses. Law enforcement interviewed mall employees, store owners, and anyone who might have seen the girls.
Despite the enormous effort, investigators found no physical evidence explaining what happened to them.
A Man Seen Watching the Girls
During the investigation, several witnesses reported seeing a suspicious man at Wheaton Plaza on the day the sisters disappeared.
The man was observed watching the girls and talking with children near The Orange Bowl Restaurant. At the time, police had little information about him, and the lead did not immediately result in an arrest.
Years later, investigators would come to believe that this man played a critical role in the abduction.
The Ransom Calls
In the weeks after the girls vanished, the Lyon family began receiving disturbing phone calls.
An unidentified man made several extortion attempts demanding money for the safe return of the children.
The most serious call came on April 4, 1975.
The caller instructed the girls’ father to bring $10,000 in cash to an Annapolis courthouse and leave the money inside a briefcase in a restroom.
Authorities monitored the drop location while the family followed the instructions.
But the ransom was never collected.
The caller later claimed he had seen police officers surrounding the courthouse and became afraid to retrieve the money. Investigators demanded proof that the girls were still alive before any additional ransom payments would be made.
The caller promised to contact the family again.
He never did.
To this day, investigators believe the ransom calls may have been a hoax or someone attempting to exploit the family's desperation.
The Mysterious Station Wagon
Another strange lead emerged just weeks later.
On April 7, 1975, a witness in Manassas, Virginia reported seeing two girls resembling Sheila and Katherine inside the back of a beige 1968 Ford station wagon.
The girls appeared to be bound and gagged.
The witness noticed the vehicle behaving suspiciously and began following it. When the driver realized he was being tailed, he ran a red light and sped west along Route 234 toward Interstate 66.
The station wagon had Maryland license plates, possibly beginning with the combination “DMT-6.” However, the final two digits were bent or obscured.
Authorities searched for vehicles matching that description across Maryland, but the lead eventually went cold.
While initially considered credible, investigators later labeled the sighting as questionable.
Decades of Unanswered Questions
For nearly four decades, the disappearance of Sheila and Katherine Lyon remained unsolved.
The case became one of the most well-known missing children investigations in the United States.
Over the years, investigators revisited the case repeatedly, interviewing witnesses again and reviewing evidence using modern investigative techniques.
But the mystery remained.
Until 2014.
A Break in the Case
Nearly forty years after the girls disappeared, investigators identified two men connected to the case:
Lloyd Lee Michael Welch Jr. and Richard Allen Welch Sr..
Lloyd Welch was 18 years old at the time of the girls’ disappearance in 1975. He was the nephew of Richard Welch.
By the time investigators focused on him, Lloyd Welch was already serving a 30-year prison sentence in Delaware for sexually assaulting a child.
During questioning, Lloyd Welch admitted he had been at Wheaton Plaza on the day the sisters disappeared. Witnesses had previously reported seeing him watching the girls at the mall.
Welch had spent years traveling across the United States working with a carnival and had a long history of sexual crimes involving young girls in several states.
Eventually, Welch confessed that he had participated in the abduction of the Lyon sisters.
A Horrifying Confession
According to statements made during the investigation, Lloyd Welch claimed he lured the girls away from the mall.
He said he later saw his uncle sexually assaulting one of the girls in the basement of his father’s home in Hyattsville, Maryland.
Welch told investigators that after the girls were killed, their bodies were dismembered.
He claimed their remains were transported to Taylor Mountain, roughly 200 miles away, where they were burned.
Authorities conducted extensive searches of the mountain area beginning in 2014.
Despite the effort, the girls’ remains were never located.
The Grand Jury Investigation
In 2014, a grand jury began investigating the Lyon sisters case.
During the proceedings, Richard Welch’s wife testified before the grand jury. Prosecutors later charged her with perjury, alleging she had lied about key details related to the case.
In July 2015, Lloyd Welch was formally indicted on two counts of first-degree felony murder connected to the Lyon sisters' deaths.
The underlying felony was abduction with intent to defile.
The Guilty Plea
In September 2017, Lloyd Welch pleaded guilty to the murders of Sheila and Katherine Lyon.
He admitted participating in the abduction, though he did not fully admit responsibility for the killings themselves.
As part of the plea agreement, Welch also pleaded guilty to two unrelated sexual assault crimes involving children that he committed in the 1990s. Investigators uncovered those crimes while examining his history during the Lyon investigation.
Welch received a 48-year prison sentence.
However, before serving that sentence he must complete the remainder of his earlier prison term in Delaware for the sexual assault of a ten-year-old child.
Given his age and sentence length, it is unlikely he will ever be released.
Possible Additional Involvement
Authorities believe Lloyd Welch did not act alone.
Investigators stated there was likely a conspiracy involving multiple people connected to the crime.
However, several individuals believed to have been involved had already died by the time the case was solved, and prosecutors said there was insufficient evidence to charge others.
Richard Welch denied any involvement in the girls’ deaths.
Meanwhile, Lloyd Welch’s father died in 1998.
During the investigation, authorities discovered possible human blood and degraded DNA evidence in the basement of Lloyd Welch’s father’s former home in Hyattsville. Unfortunately, the sample was too damaged to confirm whether it belonged to the Lyon sisters.
A Case That Changed America
The Lyon sisters’ disappearance shocked the nation in 1975.
At the time, missing children cases often received limited national attention, and there was no centralized system for tracking missing persons.
Cases like the disappearance of Sheila and Katherine Lyon helped spark major changes in the way law enforcement handles missing children investigations in the United States.
Their story contributed to increased awareness and eventually helped inspire the creation of organizations dedicated to finding missing children.
Remembering Sheila and Kate
Today, Sheila Lyon would be in her sixties.
Katherine Lyon would be close in age.
Their disappearance left an immeasurable impact on their family and community.
Even though a suspect was eventually convicted decades later, the case still lacks full closure. The girls’ remains have never been found.
Their story remains a powerful reminder of how quickly an ordinary day can turn into tragedy — and how the search for justice can take decades.
