A man with a cow slurry fetish has been jailed for five years after threatening to kill a family who tried to stop him targeting their farm.
David Truscott, 43, repeatedly rolled around naked in cow slurry and developed an obsession with a farm in Redruth, Cornwall.
Exeter Crown Court heard that Truscott, formerly of Camborne, Cornwall, targeted the property over an eight-year period to indulge in his bizarre fetish.
He initially removed cow pats from the farm but his behaviour escalated, with Truscott regularly entering Woodbury House Farm to commit a sexual act alone in slurry.
The court heard that Truscott decided to exact revenge on farmers Clive and Jackie Roth when they erected bollards and removed slurry from their cattle in a bid to deter him.
Truscott, who was jailed in 2005, 2009 and 2011 for his actions at the farm, repeatedly set fire to their shed, tractor, enclosures and hay – killing a calf in one blaze.
Last year, he admitted making threats to kill the Roth family and damage their property.
Yesterday, he was handed an extended sentence of ten years following psychiatric reports.
Judge Philip Wassall told Truscott: "When the family took steps to clear up the slurry from the cattle to prevent you from wallowing in it and took other measures to stop you getting on to their land, you began these offences.
"During a prison visit in August 2012, you made a reference to Raoul Moat and said you wouldn't mind going to prison knowing that your revenge would have been received.
"The impact on this unfortunate family, who you chanced upon and whose lives you have blighted for years, has been substantial.
"They live in fear of seeing you again."
Judge Wassall said Truscott, who has autism spectrum disorder, would spend the first five years of his prison sentence receiving hospital treatment.
He will serve an extended licence period of five years on release from prison.
The judge also imposed an extended restraining order to keep him from the farm.
Prosecuting, Eleanor Purkis said: "The defendant has a fetish in relation to animal faeces. His behaviour has escalated."
Truscott was jailed for three years at Truro Crown Court in 2005 after setting fire to the Roth's tractor, hay, a pen containing cattle and wooden fences. In September 2009, he received a 16-week sentence after he stripped naked in the cattle pen. On his release, Truscott returned to the farm and sat naked in cow muck.
