CHEVALINE, France (Reuters) - Police investigating a gruesome family murder in the French Alps are looking at several theories, including that the British man shot dead in his car with his wife and another woman was involved in a financial feud with his brother.

As forensics experts performed autopsies on the four victims, who include a local cyclist who was passing at the time of the attack, a team of French investigators landed in Britain.
