The former British design boss of Rolls-Royce, 74, was found ‘stabbed to death on his own doorstep’ at his £3m German mansion; police launched a hunt for his killer after the victim’s wife ‘jumped over the wall to escape the attacker’

A former British design chief for Rolls-Royce has been found dead on the doorstep of his own £3million mansion after being stabbed.

Ian Cameron, 74, was discovered in his home in Germany on Friday night and local media reported he had been stabbed by a man.

The incident took place at the house in Herrsching, on Lake Ammersee in Upper Bavaria, where extensive searches for escape routes and evidence were carried out.

The security cameras in the garages where he kept his valuable vehicles had their power cables cut. Sun reported.

Police have launched a hunt for the killer after Cameron’s wife jumped over a wall to escape.

Verena Kloos managed to reach her neighbor’s house and call the police.

Mr Cameron was a vintage car expert who retired from Rolls-Royce in 2013.

This was after 20 years with the company, working on the design of cars such as the 3 Series, Z8, Phantom and Ghost.

Police called it a “crime of violence” and said the attacker fled the home on foot.

Search teams are using dogs and a helicopter to locate him.

But one officer told The Sun it is “extremely rare” for a burglar who prepares enough to disable the CCTV system to then “stab and kill” a person.

The suspect is reported to be between 180 and 190 cm tall, wearing light-coloured trousers and a dark blue hoodie, carrying a red backpack and yellowish-green gloves.
