In 2004, a bungalow in the sleepy village of Trusthorpe, on the East Coast of Lincolnshire, became the unlikely setting for a brutal double killing executed with ruthless efficiency.
Joan and John Stirland, who formerly lived in Carlton were gunned down - Joan in the bedroom and her husband on the settee - on August 8. A getaway car was set on fire a few miles away after being driven down back streets, having first parked up on the kerb near the Stirland's home before they were murdered.
No-one was ever convicted of the murder but, crucially, three men were found guilty of conspiring to murder the Stirlands. The police's investigation would go on to lead them to link the executions to another shooting, this one carried out in Nottingham. During a lengthy and highly publicised trial, a court was told how the execution of the couple was a bitter reaction to the death of a young man in Nottingham called Jamie Gunn. Jamie was the nephew of Colin and David Gunn.
