France shooting: Alleged violent past of son of Alps murder victim Her husband, Mr Thaher's father, Abdul al-Saffar, died last year from kidney problems. Neighbours at their flat said they had not seen the son for about a month while Swedish relatives said they believed he had travelled to England. Documents from a local criminal court in Stockholm reveal Haydar was arrested on numerous occasions for alleged violent and threatening behaviour against his parents. However, he was never charged because they refused to testify against him wanting help for him instead, papers from the Sodertorns court show. His parents allegedly told police they believed he was schizophrenic, that he had terrorised them since 2001 and threats were made on a daily basis. In 2004 he was said to have screamed at his father: "I want to kill you and there is nothing you can to about it" to his father before hitting him. The following year he allegedly attacked his father with his own walking stick and screamed:"I can beat you and I can kill you" in Arabic. In 2006 he allegedly attacked his mother. The Hillis, from Surrey, and Mrs al-Allaf were killed in their BMW car on a secluded forest road near Lake Annecy, in south eastern France, on Wednesday last week. The Hilli's two daughters, Zainab, seven, and Zeena, four, survived the attack despite the elder of the pair being shot in the shoulder and badly beaten. A French cyclist believed to have passed at the time of the slaughter was also shot dead. One of the first people witnesses on the scene this week described it as "like a horror film." Zainab reportedly suffered such horrific facial injuries that she could be left blinded in one eye. A police source was quoted as saying: "She suffered multiple facial injuries that caused two subdural hematomas and a fractured orbital bone. She was beaten around the face with great force, the trauma was immense. A subdural hematoma is a potentially life-threatening brain injury and the orbital bone surrounds the eye. She is being treated in a Grenoble hospital and has been intubated due to massive bruising between her skull and her brain. Police are hoping that Zainab, who was shot in the shoulder and pistol-whipped around the head, will be able to provide key witness evidence, although she is not expected to be interviewed for at least another two days. In the first public statement on behalf of the families, Ahmed Al-Saffar, the brother-in-law of Mrs al-Allaf and Iqbal's uncle, said: "The victims" family and I are heartbroken by this shocking crime and we have been touched by the expressions of sympathy from people all over the world. We hope that those responsible for the deaths of our loved ones are brought swiftly to justice. Eric Maillaud, the chief prosecutor in Annecy, and the French magistrate leading the inquiry, are due to travel to Britain today to meet police officers and speak to relations of the Hilli family. There was intense police activity in the area yesterday (WEDS), exactly a week after the murders, as officers set up road blocks and stopped passing motorists.
