France shootings: origins of massacre lie in Britain, says prosector Engineer Saad al-Hilli, 50, from Surrey, his dentist wife Iqbal, 47, and her mother Suhaila al-Allaf, 74, had been shot down by a mystery gun man before Mr Martin arrived on the scene. The couple's four-year-old daughter Zeena lay undiscovered under her mother's corpse for eight hours afterwards, while her seven-year-old sister Zainab was found with serious injures after being shot and beaten. Yesterday their families released a statement in which they said they were "heartbroken" by the deaths. Mr Maillaud told reporters outside Woking police station in Surrey that it was "without any doubt that the reasons and causes have their origins in this country." He added: "It is only by being together that we will find the murderers." He thanked English authorities for their help with the inquiry. The French officials have joined a small number of French investigators already in Britain to help unravel the mystery surrounding the deaths of the three Britons along with that of French cyclist Sylvain Mollier, 45, who apparently stumbled across the attack. Mr Maillaud said yesterday that 40 French police officers were working on the complex case, which has led to a flurry of theories relating to possible motives. He said investigators were focusing on three specific areas - Mr al-Hilli's work, his family and his native Iraq - as they try to find a motive for the murders. Mr Maillaud is expected to visit the al-Hilli family home in Claygate, Surrey, this afternoon as part of his 24-hour trip to the UK and will also meet police officers and Crown Prosecution Service officials.
