It seemed the killers of Jason swift lived in Hackney, very near Jason at the time of his killing. But the gang were involved in the death of barry Lewis from South London, and Mark Tildesley from wokingham (33 miles from central London). Here is a quick timeline of disappearence and murders of boys in London from 1979 to 1988.
1979: disappeared: martin allen, 15, on southbound piccadilly line (left from kings cross). Last seen at earls court (which is where you can get connecting trains back north, or further south). Guy Fawkes night
1981: murdered by unknown person(s), Vishal Mehrota, 8, Putney in south london. Putney is on district line. Royal wedding day.
1984: Disappeared, Mark Tildesley, 7, Wokingham. Disappeared from funfair. Leslie bailey convicted of murder,
1985: Murdered, Barry Lewis, 6, walworth south london. leslie bailey convicted. Although from south London, he was apparently taken to the flat in hackney north London. Seven or eight "men" were reported to have been involved in the poor little soul's death.

1985: Killed, Jason Swift 14, Hackney north london, lured to the gangs flats in hackney. Leslie bailey et al convicted of manslaughter.
1986: Disappeared Kevin Hicks, 16, Croydon south London. Went to local shop in evening and never returned.
1988: Disappeared, Lee Boxell, 15, Sutton, South London. Last seen on sutton high street, where he said he might go to see a football match.
Four of these boys disappeared when there was something festive or celebratory going on - guy fawkes, royal wedding, funfair, football match. jason Swift disappeared near to where the gang lived, and I have no idea if there were funfairs or anythign on at the time Barry and kevin disappeared. But as they were nown to target children at funfairs, perhaps they also targeted them at big events like bonfire parties, street parties etc. It coudl be that someone set off to go to a bonfire party to snatch a child, and on the way saw Martin Allen.
