Police are investigating whether a family dispute about money was behind the murders of four people in the French Alps.

Local media claims detectives are looking for the brother of Saad al-Hilli from Surrey - who was shot dead in a car along with his wife and mother-in-law.

Post-mortems are being carried out on them and a French cyclist also killed nearby - but al-Hilli's two daughters ... aged 4 and 8 ... survived.
