As a follow up on what appears to be a professional hit in the Alps, police are questioning the brother of Saad al-Hilli concerning a possible family feud over money. Meanwhile, a witness claims to have seen a motorcycle near the scene of the killings.
A British cyclist, who is a former RAF serviceman, has told police he saw a green four-wheel drive car and a motorbike speeding towards the scene before he arrived, police said today.
It is the first suggestion of another vehicle being involved other than the 4x4.
The British witness, who gave a seven-year-old girl first aid at the scene, arrived after a French cyclist overtook him and was shot dead. His body was found near the British-registered car.
