France's state prosecutor Eric Maillaud spoke ahead of his visit to the UK today, to assist in the al-Hilli family shootings investigation in which three people were shot dead in the French Alps.
Mr Maillaud said there were three possible theories to explain the killings, as investigators wait to speak to the seven-year-old girl who survived the accident. Mr Maillaud told a press conference in the French city Annecy:
Today there are no suspects, but different theories, and I can tell you that in this very complex investigation, there are three possible theories.
There's the theory of a family conflict between the two brothers regarding a sum of money or inheritance. We have some elements concerning the financial conflict between the two brothers, but the brother in Britain denies this, he says he was on good terms with his brother.
We have the theory about the profession of Mr al-Halili and we have the theory about his origins in Iraq.
Brett Martin, the first witness who found the British family in the Alps has described the moment he came across the attack.
A friend of the al-Hilli family has said he believes he could assist the investigation into the fatal shootings of the three family members.
A previously unreported witness has told a French paper how he came across the aftermath of the killings of the al-Hilli family in the Alps.
