The only identifiable body part from the bombers to survive the blast (which had been heard up to four miles away) was a severed arm belonging to Wesley Somerville. It was found 100 yards from the site with a "UVF Portadown" tattoo on it. The RUC's investigative unit, the Assassination or "A" Squad of detectives, was set up to investigate the crime and to discover the identities of the UVF gunmen who perpetrated the killings. Afterwards, as Travers recovered in hospital, the other survivor Des McAlea gave the police a description of McDowell as the gunman with a moustache and wearing dark glasses who appeared to have been the leader of the patrol.
