On the morning of March 25, 1975, Sheila Lyon, 12, and her younger sister Katherine, 10, left their home in Kensington, Maryland. They walked half a mile to Wheaton Plaza to see Easter decorations and meet friends for pizza. Their mother, Mary, told them to be home by 4 p.m. Their older brother Jay saw them eating pizza at the mall. It was the last time any family member saw them alive.
When the girls did not return, the Montgomery County Police launched the largest search in the history of the Washington, D.C., area. Hundreds of people combed the woods around Wheaton. They found no trace, no clothing, and no reliable witness. Two children had vanished in broad daylight, half a mile from home, in a neighborhood where neighbors looked after one another's kids.
A week after the disappearance, the perpetrator approached police himself at Wheaton Plaza. He was an 18-year-old carnival worker with a face marked by acne scars. He claimed he witnessed the abduction. Police gave him a polygraph test. He failed it, but they let him go. No one checked the sketch a witness had provided describing a young man who looked exactly like him. The sketch stayed in the file, forgotten for 38 years.
It took 42 years, a cold case team that refused to give up, and a yellowed sketch that matched an old mugshot to bring the case to a close. This is the story of Maryland's most haunting disappearance and the longest road from crime to justice.
John Lyon was one of the most recognizable voices in Washington, D.C. He worked as a radio announcer at WMAL in Bethesda, and hundreds of thousands of listeners heard him every morning on their commute. Colleagues called him "the swinging man" for his ability to appear on air at any time. He had built a 22-year career at the station.
His wife, Mary, kept the family's life running. They had four children: Jay, Joe, Sheila, and Katherine. The family lived in Kensington, a quiet middle-class neighborhood with tree-lined streets where children played outside until dark and neighbors left their doors unlocked.
In 1975, America did not yet know the phrase "stranger danger." There were no missing children photos on milk cartons. There was no AMBER Alert system. Children walked to school, to the park, and to the shopping center freely. No one thought that freedom could cost a child their life.
Sheila and Katherine were typical girls of that era. They had savings in piggy banks. Posters of John Denver and Kenny Loggins hung on their bedroom walls. The walk to Wheaton Plaza was as familiar as the walk to school. Sheila was the older sister, tall, thin, blonde, and shy but determined. Katherine was younger, quick to laugh, and kind in a way friends still remembered decades later.
The girls were on Easter break. The weather was warm. They wanted to see the Easter decorations, meet friends, and have lunch at the Orange Bowl restaurant. Mary agreed and suggested they get pizza. She told them to be home by 4 p.m. The girls took four dollars and left the house at 11 a.m.
At Wheaton Plaza, things seemed normal. The sisters met friends, browsed the stores, and sat down for pizza. Their brother Jay saw them and waved. After 2 p.m., the girls left the mall. There was plenty of time to get home before four. But the front door stayed closed.
Mary waited. She called neighbors and friends. No one had seen the girls. As darkness fell, she called Montgomery County Police. From that moment, the Lyon family's life split into before and after March 25.
Police conducted hundreds of interviews and followed hundreds of tips. Nothing led to Sheila and Katherine. At home, the girls' bedrooms remained untouched. The piggy banks stayed on the desk. The four dollars were never spent. Everything stayed as if the girls had just stepped out and would return any moment.
In the early days, police gathered many witness statements. One witness, a boy from the neighborhood, said he saw Sheila and Katherine talking to a man outside the Orange Bowl. The man was described as in his 50s or 60s, about 6 feet tall, wearing a brown jacket, and carrying a bag with a tape recorder inside. He had let children speak into a small microphone and asked them to read a message printed on a card.
Police focused immediately on this man. They drew two sketches and published them widely. The media called him "the tape recorder man." This lead seemed promising. Many witnesses came forward saying they had seen him at the mall that day. Reports surfaced that he appeared at other shopping centers, approaching children and asking them to read into the microphone.
The investigation devoted all its resources to finding the tape recorder man. Weeks passed, then months. Eventually, the lead went nowhere. The man with the tape recorder was just someone testing new equipment. He had nothing to do with the disappearance. All the resources, time, and public attention had been poured into a false lead.
But that was not the fatal mistake. The fatal mistake lay in a second sketch that almost no one knew about. While police focused on the tape recorder man, another witness gave a very different statement. A girl who was a friend of the sisters told investigators she saw a young man staring at Sheila and Katherine at Wheaton Plaza. She said he stared so intently that the sisters felt uncomfortable.
The girl described the young man as about 18 to 20 years old, with long hair, a face covered in acne scars, wearing disheveled clothes, about 5 feet 11 inches tall, and weighing about 140 pounds. An investigator drew a composite sketch based on her description. The sketch was clear, detailed, and very close to the actual face of the person described. But that sketch was never published. Police were focused on the tape recorder man, and the sketch of the long-haired young man was filed away. It stayed there, in a drawer inside a filing cabinet, for 38 years.
On April 1, 1975, exactly one week after the girls disappeared, an 18-year-old named Lloyd Lee Welch Jr. voluntarily approached security at Wheaton Plaza. Welch claimed he had been at the mall the day the girls vanished. He described seeing the sisters leave with a man matching the tape recorder man description. He gave a detailed statement.
Montgomery County Police gave him a polygraph test. He failed it. Police thought he was someone trying to claim the $9,000 reward offered for information. They released him. No one during the entire interrogation checked the second sketch, the one of the long-haired young man with acne scars and disheveled clothes. If they had, they would have seen what another investigator discovered 38 years later. Lloyd Lee Welch Jr. was the person in that sketch. The face matched. The age matched. The long hair matched. The acne scars matched. The disheveled clothes matched.
The perpetrator had walked into the police station himself, sat before investigators, failed a polygraph, and was released. He walked out the door and vanished from the investigation for nearly four decades.
In March 1975, Welch was an 18-year-old high school dropout working as a game operator for a traveling carnival. He had no fixed home, no steady job, and had already begun building a criminal record as a teenager. He moved from place to place, and wherever he stopped, children were not safe.
Over the years, Welch became a convicted serial sex offender in several states. He was arrested in South Carolina, Delaware, and Virginia. Court records later documented 14 offenses, including rape, beating, and assault with a knife, spanning from 1973 to 1997. Ten women later prepared to testify that Welch had attacked them or attempted to kidnap them.
After Welch slipped out of the investigation, the Lyon sisters case slowly died. Investigator Pete Engels, assigned to the case the day after the disappearance, spent more than half his working hours chasing tips. Thousands of calls and hundreds of statements from friends, neighbors, and acquaintances. Private investigators were hired. Psychics called. None of it led anywhere.
By August 1975, five months after the disappearance, Mary Lyon had lost hope. She believed her daughters were dead. It was not surrender. It was a mother looking at reality directly and deciding that living in illusions would not protect her remaining children.
The community changed almost overnight. Before March 25, 1975, parents let their children walk to the mall without a second thought. After that day, they never did again. Children were no longer allowed to play outside until dark. They no longer walked to school alone. Wheaton Plaza, the place where the sisters were last seen, became a symbol of fear.
John Lyon continued broadcasting on WMAL until 1990. After leaving the station, he became an advocate for victims' rights in Montgomery County, counseling other families dealing with tragedy and loss. He turned his personal pain into something useful for others.
In 1997, Welch was arrested in Delaware for sexually assaulting a 10-year-old girl. He was convicted and sentenced to 33 years in prison. He sat in a Delaware prison less than 150 miles from Wheaton Plaza, and no one in the justice system connected his name to the 1975 disappearance of the Lyon sisters.
In 2013, the cold case team at Montgomery County Police was assigned to reopen the Lyon sisters file. A young investigator was flipping through the yellowed pages when he stopped at the second sketch. The one never published. A young man with long hair, acne scars, and disheveled clothes, about 18 to 20 years old.
He looked at the sketch, then moved to another section of the file. The section listing people who had contacted police during the original investigation. There was the name Lloyd Lee Welch Jr., the man who approached security at Wheaton Plaza on April 4, 1975, claiming he witnessed the abduction.
The investigator searched for a photo of Welch in the system and found one taken in 1977 when Welch was arrested for theft near Wheaton Plaza. He placed the 1975 sketch next to the 1977 photo. Long hair, acne scars, same age, same build, same face. The sketch and photo were almost identical.
Two pieces of the puzzle had been in the same filing cabinet, the same case, the same police station, for nearly four decades. No one had put them together.
Cold case investigators traveled to Delaware to interview Welch. In the first interview, Welch admitted he was at Wheaton Plaza on March 25, 1975. He admitted he saw the Lyon sisters. Then he said something unexpected. He admitted he left the mall with the girls. But he blamed others. He said he handed the girls to his uncle, Richard Allen Welch Sr. He said he saw his uncle assault them. Then he said he left.
Investigators did not believe him. The story kept changing. In every version, Welch placed himself at the center of the abduction. He always admitted leaving the mall with the girls and always blamed someone else for the worst violence.
In February 2014, Montgomery County Police officially named Lloyd Lee Welch Jr. as a person of interest in the disappearance of the Lyon sisters. It was the first time in nearly 39 years the public knew there was a specific suspect. In October 2014, police named Richard Allen Welch Sr., Lloyd's uncle, as a second person of interest.
The investigation led investigators to Taylor Mountain in Bedford County, Virginia, about 200 miles from Wheaton Plaza. The Welch family owned land there. Investigators believed Sheila and Katherine had been taken there after the abduction, and that their bodies may have remained there for nearly four decades.
In September 2014, cold case investigators began the first excavation on Taylor Mountain. They dug. They sifted soil through fine screens. They brought in cadaver dogs. The search lasted days in difficult terrain and harsh weather.
Two cousins of Lloyd Welch told investigators he appeared suddenly in the spring of 1975, without warning and without clear reason. He arrived with bloodstained clothes. A relative named Dolly Astep told a reporter that investigators came to her home months before the digging. They told her two of her uncles were connected to the disappearance of two sisters in Maryland in 1975.
The first excavation found no bodies. A second excavation in January 2015 also found no remains. But investigators found other things: evidence of old fires, objects in the soil consistent with the mid-1970s, and growing testimony from Welch family members about what they had seen and heard.
When a grand jury in Bedford County began calling witnesses, Welch family members entered the courtroom one by one and lied. Patricia Welch, wife of Richard Allen Welch Sr., was charged with perjury after testifying before the grand jury in December 2014. Leslie Engling was also charged with perjury. Gladys Stange and Amy Welch Johnson were each charged with obstructing justice. Four people connected to the Welch family were charged for the same reason. They knew something about what happened on Taylor Mountain in the spring of 1975 and deliberately hid it.
On July 15, 2015, exactly 40 years after the disappearance, the grand jury issued its decision. Lloyd Lee Welch Jr. was indicted on two counts of first-degree murder. The indictment was announced at a press conference in Wheaton, Maryland. John and Mary Lyon, now in their 70s, sat quietly in the back and heard their daughters' names read in a murder indictment for the first time in 40 years.
According to the indictment, the Lyon sisters were kidnapped from Wheaton Plaza and taken to Bedford County, 200 miles away, where they were killed sometime between the day of the abduction and three weeks later. Their bodies were never found. The indictment included first-degree murder charges that could carry the death penalty.
Ten women prepared to testify that Lloyd Lee Welch had attacked them or attempted to kidnap them between the 1970s and 1990s. Court records described 14 separate offenses from 1973 to 1997: rape, beating, assault with a knife, and kidnapping. This was the man Montgomery County Police had looked directly in the face on April 1, 1975, when he came to them voluntarily and failed a polygraph. They opened the door and let him leave.
The path from indictment to trial was not simple. Welch was still serving his sentence in Delaware. He had to be extradited to Virginia. Defense attorneys filed appeals. Trial dates were set and postponed. On September 12, 2017, 42 years after that spring morning, Lloyd Lee Welch Jr., now 60, stood before the Bedford County Circuit Court and spoke the word the Lyon family had waited more than half their lives to hear: guilty.
Welch pleaded guilty to two counts of first-degree murder in the disappearance and deaths of Sheila and Katherine Lyon. The judge sentenced him to two terms of 48 years in prison, to run concurrently. By pleading guilty, Welch avoided the death penalty, which prosecutors said they would have sought had the case gone to trial.
But Welch's guilty plea carried a contradiction the Lyon family would have to live with for the rest of their lives. He admitted the kidnapping. He did not admit to sexually assaulting the girls. He did not admit to killing them, even as he stood in court pleading guilty to first-degree murder. He continued to blame his father and his uncle for the worst violence.
Prosecutors did not believe him. Investigators did not believe him. But the guilty plea closed the case. Welch went to prison for the rest of his life. It gave the Lyon family what they had waited 42 years for. Not full closure, not the complete truth, but at least the acknowledgment that their daughters had been harmed by a specific human being with a name and a face who now had to pay the price.
After the hearing, John Lyon stepped toward the microphones. He did not speak about pain or anger. He spoke words of thanks. He said the cold case team had treated Sheila and Kate as if they were their own sisters or daughters. He said, "We just want to say thank you simply." Then he smiled a slight, sad smile. He said, "We're tired and we just want to go home." Mary Lyon stood beside him, wiping her tears.
Prosecutor Wes Nance told the press, "This is a good day for justice, but it will not bring closure, and it will not provide all the answers the family deserves." What exactly happened after the girls were kidnapped from Wheaton Plaza. Who else was involved. Where the bodies were. Welch knew, but he refused to speak.
On October 29, 2024, an FBI response team and U.S. Marshals returned to Taylor Mountain with a federal search warrant. They dug in the basement of a house on the mountain. They kept digging in the soil all day. No one confirmed whether the search targeted the remains of Sheila and Katherine or involved other victims of Welch. Nearly 50 years later, the mountain still held its secrets, and the Lyon family was still waiting.
Mary Lyon died in 2024. She lived long enough to see the conviction of the man who kidnapped her daughters. She did not live to learn where her daughters were buried. John Lyon died on June 26, 2025, at age 85, in Annapolis, Maryland. At the end of his life, he lived alone after his wife's passing, without his daughters ever coming home.
Jay Lyon, the boy who saw his sisters eating pizza for the last time in 1975, became a police officer and then a homicide investigator. He did not choose that career by accident.
March 25, 1975. Sheila Lyon, 12, and Katherine Lyon, 10, left their home in Kensington, Maryland. They had four dollars in their pockets. Their mother told them to be home by 4 p.m. Forty-two years later, a 60-year-old man stood in a Bedford County, Virginia, courtroom and said two words: guilty. The bodies of Sheila and Katherine were never found, but their names were never forgotten.
