DETECTIVES are today trying to establish a motive for a shooting which left a farm owner dead and his son seriously injured.

Peter Thompson, 59, was killed and his son John, 36, shot in the leg at Meadowhead Farm and riding school in Auldhouse, near East Kilbride, yesterday at around 8.10am.
The 53-year-old attacker, named as Robert McCormick, is then believed to have turned the gun on himself. His body was found in a nearby car.
Two hours after the shooting, armed officers were scrambled to the street where Mr McCormick lived in Clarkston, East Renfrewshire.
Neighbours watched as armed officers forced open the door of his house.
And there was still a heavy police presence in the area today with searches focusing on Mr McCormick’s property. Local residents spoke of their shock after learning Mr McCormick had been involved in the tragedy.
It is understood Mr Thompson and Mr McCormick, who is thought to have a farming background, had been doing business together.
After the incident Mr Thompson’s son John fled to nearby Auldhouse village in a car and was given first aid by a construction worker outside the Auldhouse Arms Pub before being airlifted to Hairmyres Hospital.
Dozens of armed police officers, supported by a helicopter, raced to the scene after the injured man raised the alarm.
Auldhouse residents spoke of their fear after ­being advised by police to stay indoors while the ­entire village was put into lockdown by police.
Police in Auldhouse also seized a van belonging to Glasgow company Ryan Plant Hire. It is understood to be the vehicle that John Thompson used to drive into the village.
Superintendent Elaine Ferguson said: “We are not looking for anyone else in connection with the incident.
“It was a contained ­incident. There’s a linked incident that happened in Clarkston area of Glasgow and that’s resulted in us identifying a witness but that witness wasn’t in the farm at the time of the shooting.
“The scene has now been handed over to the CID ­officers. They have attended there with a number of other specialist resources.
“They will conduct their inquiries to find out exactly what the circumstances were that led to this tragic incident.”
John is Peter’s son from his first marriage to Mary Ewing. The couple wed in Rutherglen in June 1974 and also had a daughter Caroline, 29. Peter and Mary divorced in   2004.

JOHN, who has a young child with his long-term partner, had a paintballing business registered at his family farm.
Both he and his father had encountered business difficulties in the past.
Mr Thompson is understood to have been embroiled in a long-running feud with neighbours over an access road leading to his property and damage caused to it during building works at his equestrian centre.
He was also fined £10,000 last year for unauthorised tipping at the farm.
Mr Thompson and his son were granted permission in 2000 to develop their riding school into an international standard equestrian centre.
He approached the council 10 years ago to ask that Meadowhead Highway – an access road for his property and seven other properties – be made a private road, giving him and the other property owners responsibility for it.
He made the request ­because of the road’s poor condition and lack of maintenance, but the ­council turned him  down.
The council later spent £80,000 re-laying the road to allow for public access and indicated they would remove the road from the List of Public roads, ­essentially handing ownership of the road to Mr Thompson.
However, it is understood it later decided it was not a feasible option after it ­received three objections as part of their consultation process.
One local resident said: “He has incensed locals with his illegal dumping at the farm and the damage caused to the roads by his big trucks.”
Tributes to the family were posted on the farm’s Facebook page.
