The first article I posted the link to includes a Gemini Crew murder that isn't listed in Murder Machine or any list of DeMeo Crew murders.

"As the demand for loops increased, Tom needed more help and gave work to Lloyd ‘Smitty’ Smith, a tall, hard-working guy from the West Indies who worked closely with Bill Luxe. Smitty lived around the corner from Tom on 48th Street above a bar called The Golden Oaks. Smitty often shot and edited films in his own apartment.

Tom was known to be careful with his money, not to mention greedy at times, and this could cause problems for him. Smitty put together a one-day-wonder film for Tom, and was angry when Tom didn’t pay him. Smitty began making a lot of noise about the debt. Tom complained to Roy DeMeo and in such a small but highly profitable business, DeMeo didn’t want quarrels that would elicit unwanted attention. Any problems had to be snuffed out swiftly and efficiently.

Bill Luxe, Smitty’s friend, remembers clearly what happened next: “Roy DeMeo came knocking at my door and said he knew Smitty was with me. He said Van der Feer worked for him and that I should tell Smitty not to go near Tom. I passed Roy’s message on to Smitty – and told him that coming from DeMeo it meant a threat. Smitty didn’t listen. He was a hot head and he went to Van der Feer’s place in Times Square, wrecked his studio and took a camera for the money Tom owed him. Next thing I heard was that Roy DeMeo had called Smitty out to the Gemini Lounge for a sit-down with Van der Feer. I talked to Smitty before he went out to the Gemini. He said he’d call and let me know what happened at the sit-down. That night my wife and I were up until after midnight waiting for Smitty to call, but he never got in touch. I was at the lab the next day and Roy was there. I asked how the sit-down went and was told, “Sit-down? What sit-down?” I knew not to ask too many questions, so I let it slide. That was the last anybody ever heard from Smitty. There was no doubt in my mind that Smitty got the Gemini treatment.”

There was no police investigation into Smitty’s disappearance.

Tom continued to make loops under the protection of DeMeo."
