Kidnapped Quinn boss Kevin Lunney was tortured and mutilated in an old horse box, Gardai believe.
Forensic experts were yesterday completing a two-day examination of the scene where the father of six endured horrific “life-changing” injuries.
Among the traumatic wounds is a double leg break – the result of repeated blows from a heavy bar.
The 50-year-old Quinn Industrial Holdings executive also suffered deep slash wounds from a blade during the prolonged and sadistic onslaught.
He was stripped during the brutal attack which lasted more than two hours.
His fingernails were brutally cut away as his abductors attempted to destroy DNA evidence.
The sealed-off site at Ballinagh, Co Cavan, where garda operations continue, is 23 miles from Kinawley, Co Fermanagh, where Mr Lunney was rammed off the road as he returned home from work last Tuesday night.
All roads in and out of the crime scene were also cordoned off.
The area is just three miles from the parish of Cornafean where Mr Lunney was finally dumped by the gang.
A passing farmer sitting high in a tractor spotted the seriously injured man at around 9pm.
Mr Lunney was too weak to move and if he hadn’t been found, his injuries and weakened state could have proved fatal.
Meanwhile, the cross-border investigation has made significant progress.
Gardai believe one of the ring leaders is a notorious criminal based in Cavan.
He was spotted buying a large container of industrial or agricultural bleach which the gang used to try and destroy forensic evidence.
Mr Lunney’s body, including his open wounds, were doused with the corrosive.
CCTV footage of the purchase is being examined by Garda technical experts.
More than a dozen thugs with links to serious crime and paramilitary activities may have been involved in the carefully-planned abduction.
One of two cars used to ram Mr Lunney off the road was stolen months ago.
That vehicle and Mr Lunney’s were both torched at the scene of the abduction and his family faced the agony of fearing he was still inside the blazing wreckage.
Those worries were only allayed after a search by emergency services.
The other car, a black Audi, is still missing and the subject of an intensive search on both sides of the border.
