I seriously think one or more of that gang could be involved. They are believed to have targeted children from at least ages six to fourteen. Martin was in school uniform and was only five foot so he would have appeared younger. I believe they also buried Jason Swift who was found, but Mark Tildesley was never found. We also know there are reports of at least two of them abusing boys in the 1970's, and I read somewhere at least one of them had stayed in North London. I am sure whoever took him must have committed other crimes, if not before then certainly after.
The only thing that makes me think there might not be a connection is that surely the police must have investigated this possibility. I have never read about them having done so, but they apparently looked into whether Dennis Nilsen was a suspect, so why not these known paedophiles and child killers.
There are also more case of young murdered boys in london in the early 1980's.

eight year old Vishal Mehrota disappeared in Putney (sw london) on 29 july 1981 (royal wedding day). One thing I noted is that Putney is also on the district line like gloucester road and earls court. Someone travelling from kings cross to putney could take the piccadilly line to earls court, then district line to putney.

- towards the end this tals about how leslie bailey, one of the gang, and according to the article lover of lennie smith was jailed for the 1984 murder of six year old barry lewis from walworth south london.
http://www.thefreelibrary.com/I+did...uch+evil+things+..;+IF+YOU+EVER...-a060681507 - talks about the gang's other killing with focus on jason Swift who it appears lived near to them in hackney. apparently they are suspected of twelve killings. I still do not understand why a group of men gang raping and drugging a child to death, get not only a manslaughter and not murder charge, but serve just nine years.
Another thing that maes me wonder if it could eb them is the fact that they apparently used fun fairs and carnivals to lure children. It was Guy fawes night when Martin disappeared, could they have used this to get him talking to him, there often is a party like atmosphere at guy fawkes. Tenious link I realise, but the facts are someone abducted him and not for a nice reason, someone murdered him and hid the body, and in the early 1980,s and possible 70's there was a paedophile gang in London that are known to have killed children from different areas in London.
