The boss of an animal rendering firm has been cleared of the manslaughter of an employee who died after falling into a pit of offal.
Mr Thompson died later in hospital
John Pointon and Sons, in Cheddleton, Staffs, and director Carl Pointon were charged over the death of 45-year-old Glynn Thompson in August 2004.
Mr Thompson was trying to rescue Ivan Torr when he slipped and fell.
The firm has been found guilty of health and safety charges and will be fined at a later date.
Overcome by fumes
The company admitted breaching two health and safety rules but denied two others at Stafford Crown Court.
Earlier in the trial, the court was told how Mr Thompson, from Stoke-on-Trent, was lowered on a crane manned by Mr Pointon.
The two men were overcome by fumes and although Mr Torr, from Kingsley Holt in Staffordshire, survived, Glyn Thomson later died in hospital.
William Davis QC, prosecuting, said the firm had installed a new enclosed rendering process area which meant lorries could dump the animal waste directly into a pit for processing.
