A GRISLY police video of the remains of murdered youngster Jamie Lavis has been found behind a city centre pub.The tape, which pans over the scene of the eight-year-old's murder at Reddish Vale, Stockport, shows fragments of Jamie's bone and clothes. It was found by a refuse collector - along with other tapes and legal documents - in a black bin bag in an alley behind the Sawyers Arms in Deansgate, Manchester. The bag had come from legal firm Cunninghams, in nearby Peter Street. Philip Lythgoe, a partner at the firm, said: "We do not know how it came to be there. Normally papers and tapes are destroyed after a certain period of time."Jamie's mother Karen Spooner, 39, said she was appalled the tape of her son's remains had been found in an alleyway. She said: "I am shocked. I can't understand how this film could have been left in a street. I thought all the evidence from the trial was kept somewhere safe."She added: "We try and deal with the pain as best we can, and sometimes things seem a little better. But something like this knocks you back." The 13-minute film, in a Greater Manchester Police cassette case, is entitled "Discovery of Human Remains. Reddish Vale Golf Club 24.10.97".Jamie, from Buckley Street, Openshaw, disappeared on May 5, 1997, after spending several hours on a bus driven by Darren Vickers. His decomposed torso, wax jacket and Reebok tracksuit was found at Reddish Vale five months later. His legs, arms and head were never discovered.In April 1999, father-of-four Vickers, now 29, was convicted of abducting, sexually assaulting and murdering Jamie. After Jamie's disappearance, he had befriended Jamie's family as police searched for the youngster. Just before he was sentenced Vickers confessed to the killing, only to withdraw the confession after being jailed for life.Cunninghams represented Vickers' sister Sheree when she and four relatives and friends of the killer were accused of providing him with a false alibi. All five walked free from court when the prosecution abandoned the case.The three-hour video includes a number of short films used as evidence in the murder trial. But the first one, focusing on Jamie's remains, is the most horrific. On the same tape, there are filmed interviews with Ashley Dair and Zoe Austin, 14, who tell police officers how they met Vickers in the woodland as the search for Jamie went on.
