On 28 April 2010, 68-year-old grandfather Barry Rubery returned home from an evening out at a Masonic dinner. After letting himself into his property in Iron Acton, a rural village in south Gloucestershire, he was subjected to a violent and sustained attack.
The next morning Barry was found dead in the conservatory of his home. He was found face down, tied up with electrical flex and cable ties. Twelve years on, Barry's murder remains unsolved.
Detective Chief Inspector Mark Almond is now the eighth senior investigating officer in the investigation into Barry's murder. He revisits the scene of the crime and various lines of enquiry in the hope of making new ground.
