A five-day operation has begun at a farm in East Eckington, Lincolnshire, as police search for the remains of James Brodie.
Specialist search teams are at Maize Farm, investigating the disappearance of Brodie, who went missing shortly after jeweller Marian Bates was shot dead during a robbery at the Time Centre, in Arnold, in September 2003.
Brodie who was 20-years old in 2003, was also wanted for three armed robberies and a racially aggravated assault.
The police want to see those behind his possible murder brought to justice.
