Killer father filmed on CCTV.

MILLIONAIRE businessman Christopher Foster was filmed by his own CCTV cameras firing a rifle at a horsebox shortly after he killed his wife and teenage daughter, say detectives.

Ending days of speculation surrounding the fate the Foster family, police said the 50-year-old took his own life after setting fire to pounds 1.2m Osbaston House in Maesbrook, Shropshire.

Detective Superintendent Jon Groves said: "CCTV recovered from the house shows a man, who we strongly believe to be Mr Foster, in the grounds of the property during the early hours with what appears to be a rifle in his hands.

"It also shows outbuildings going up in flames around the same time and a large horsebox being moved down the driveway, in front of the gates to the premises.

"A man, again believed to be Mr Foster, is seen to get out of the vehicle and apparently shoot out two of the tyres."

Det Supt Groves said officers believed that Mr Foster killed his wife Jill, 49, and their 15-year-old daughter Kirstie, before setting fire to their mansion.

Detectives have established that Mrs Foster died of a gunshot to the head before the fire started, but are still awaiting the results of a post-mortem on a body thought to be that of Kirstie.

Emergency services called to the property at about 4am on August 26 found three horses and four dogs which had been shot dead.

Searches of the house led to the discovery of a .22 rifle, owned by Mr Foster, near his body and that of his wife.

Police are not looking for anyone else in connection with the deaths.

Mr Foster's company, Ulva Ltd, which had gone into liquidation, faced legal action from a supplier for thousands of pounds and owed about pounds 800,000 in tax.
