Police hope a worldwide audience for a new TV documentary on the horrific murder of supermarket worker Alan Wood could help solve the case.
Alan (50) was tortured over some hours – repeatedly stabbed in the head – and had his throat slit, the fatal wound that saw him bleed to death at home in Lound, near Bourne, in October 2009.
Once Alan was dead, his killers tried to cut off his head.
Police believed at the time that Alan was tortured for his PIN numbers as several hundred pounds were drawn using his bank cards.
Circle Films is making a documentary for CBS Reality, which will be shown around the world in the autumn, and have interviewed police, Alan’s friends and members of the press, including Peterborough Telegraph reporter Stephen Briggs.
Stephen said: “Alan’s murder is one of the most violent and terrifying I have covered.
“It is important for Alan’s family and friends for the culprits to be caught and brought to justice after all these years.
“Someone out there must know who is responsible, and can provide answers for Alan’s family.”
Lynne Harrison, a reporter for the Peterborough Telegraph’s sister paper, The Lincolnshire Free Press also took part in the documentary.
She said: “Alan was last seen alive on October 21 and found dead three days later.
“He was an ordinary man who suffered an extraordinary, terrifying and unimaginable ordeal over a number of hours before he was savagely killed.”
Circle Films producer Charlotte Blennerhassett said: “It is one of the most brutal murders that I have ever come across.”
Chief Supt Stuart Morrison, who is leading the murder hunt, is pinning his hopes for a breakthrough on DNA from one of the attackers found at Alan’s home and says the new film “may help us to find the owner of that DNA”.
Anyone with information about Alan’s murder is asked to call Lincolnshire police on 101, or Crimestoppers, anonymously, on 0800 555 111.
