In the early seventies, there was a documentary broadcast on TV featuring an interview with a ‘gangland’ character. He claimed that he would ‘bump’ someone off for £1,000, and showed the reporter a hand gun.
He was asked about the fate of any of the other underworld people, who seemed to have disappeared. He told the reporter that they had put one body through a mincer and fed it to pigs and the other one was ‘holding up the motorway’.
He briefly said they put the body into the shuttering which was subsequently filled with concrete.
There was also a TV series called ‘Big Breadwinner Hog’, a short series about a couple of criminal gangs. In one scene, the mother of a main character had died and was cast into a concrete lintel.
If anything, it was food for speculation.
