The identity of the boy who provided Montgomery County Police sketch artist Davis Morton with the information and description of the Tape Recorder Man (TRM) was never released by MCP or the news media.
The boy, referred to in the media as "Little Jimmy", was 12 years old in March 1975 when he claimed to have seen the Lyon Sisters talking to TRM near the Orange Bowl pizza restaurant.
"Jimmy" was not his real name, but one given to him by the Washington TV and Newspaper reporters. A few years ago, an associate located him, called him, and asked a number of questions. He was reluctant at first to talk but did confirm that he remembered TRM and his interviews with MCP and the news media.
Unfortunately, his memory of specifics did not exactly match what was reported back in 1975. He recalled clearly riding his bike along with a close friend to Wheaton Plaza that day. He also recalled seeing TRM near an escalator or stairway but did not mention the Orange Bowl.
When the sketch was released to the media, nearly 15 other people called in to say that they had seen the same man with his tape recorder 2 or 3 days earlier at both the Iverson and Marlow Heights Malls (adjacent shopping centers) in Prince Georges County. In fact, these people were so sure that it was the same man, based on the picture and description, that Davis Morton took their suggestions for slight changes in the mouth area of his drawing and incorporated them in his second version of the sketch.
Other than Little Jimmy and his friend, investigators could not find anyone else who remembered seeing TRM on Tuesday, 25 March 1975 at Wheaton Plaza. When police showed the TRM sketch (prior to media release) to various store clerks and personnel, only three said that they thought they saw him there - but all said separately that they had seen him the day before (24 March).
At least two other people stated that they had seen a man who resembled the TRM sketch talking to children at Wheaton Plaza a couple of weeks before the Lyon Sisters went missing. He was also reportedly seen at other Malls in Prince Georges County on previous occasions. These were Bowie Mall, Iverson Mall and White Oak Mall. But after 25 March 1975, all sightings stopped.
It is possibly significant that Iverson Mall and Marlow Heights Shopping Center where 15 persons reported seeing a TRM the previous weekend are very close to the cabinet workshop of Raymond Mileski, and also not far from his residence.
In the days that followed release of the TRM sketch, the papers reported that MCP had interviewed about 3 men in Prince Georges County but had not developed them as suspects at that date.
Raymond Mileski had a house or building of some sort that he rented to work on kitchen cabinets, and this was located somewhere in the vicinity of Beech Road and Route 5, only a mile south of Iverson Mall. His residence was on Suitland Road, to the east of Beech Road and due north of the entrance to Andrews Air Force Base. There is much more information about Raymond Mileski in the thread titled "Potential Suspects" in the missing Lyon Sisters topic area.
Mileski was convicted and sentenced to prison for the murder of his wife and son in 1977. Of all the possible suspects in the Lyon case, only Mileski and Lloyd Lee Welch, Jr. admitted to having knowledge of the girls' abduction and murder. Mileski died in prison, but in 2013, when reviewing the case file, MCP detectives decided to locate Lloyd Lee Welch, Jr. who had approached a Wheaton Plaza security guard on 1 April 1975 stating that he had seen someone who resembled the TRM sketch abducting the girls. Welch hoped to claim a reward being offered. He gave his information, including his name and address and was sent away by MCP officers.
In 2013, MCP Cold Case Detectives at first wanted to locate and question Welch about Raymond Mileski - whether he knew him or could identify him as the TRM. They found that Welch was incarcerated in a Delaware prison and began a series of interviews with him, which eventually led to him being identified as a suspect and to his confessing to murdering Sheila and Katherine Lyon.
So, in a sense, the TRM sketch by Davis Morton did eventually lead to a resolution in the case. But who was the TRM? And how did he factor into the case? Was he working with Welch?
Besides the Tape Recorder Man (TRM) sketch, Davis Morton also made another separate sketch of an unknown young Long-Haired Man (LHM) who had been described by a young girl as following and watching Sheila and Katherine on 25 March 1975 at Wheaton Plaza.
While the TRM sketch was given wide dissemination to the News outlets and seen in all the area newspapers and on all the TV channels, the LHM sketch was kept secret. It may have been showed to potential witnesses on a one-to-one basis, but it was never released to the media.
In 2014, when the Montgomery County Police called a big news conference to announce the identification of a suspect in the case (Welch), most of the TV stations in anticipation were showing the old TRM sketch, along with 1975 footage and photos of the Lyon sisters. Then, at a point near the end of their presentation, MCP unveiled a photo of Welch taken in 1977 alongside a large poster of the LHM sketch. From that point on, they made no further mention of the TRM.
