Police have begun their search of the family home of a couple shot dead with two other victims in the French Alps.
A team of four French officers have travelled to the UK to work with British detectives at the house of Saad al-Hilli in Claygate, Surrey.
Iraqi-born Mr al-Hilli, 50, was gunned down in his car alongside his dentist wife, named by neighbours as Iqbal, on Wednesday. An older Swedish woman travelling in the car was also killed, along with Sylvain Mollier, 45, a French cyclist who apparently stumbled across the attack in Chevaline.
Police set up a forensic search at the family's Surrey home
The couple's four-year-old daughter Zeena lay undiscovered under her mother's body for eight hours after the murders, while her seven-year-old sister Zainab remains in a medically induced coma after being shot and beaten.
Officers from Surrey Police have erected a tent at the front of the al-Hillis' house as they prepare to conduct a search of the property with the French police team, led by officer Marc de Tarle.
Floral tributes from friends and neighbours within the shocked community have continued to be taken by police and displayed outside the two-storey property.
Dozens of floral tributes have been left for the family at their home
Two female officers have taken boxes containing equipment and evidence bags into a tent erected outside the home as they prepare to search it for the first time.
Police wore white scenes of crime overalls to conduct the search, which is expected to be a joint operation with French officers who flew to the UK on Friday. However, no French officers are yet at the scene.
Police plan to look at aspects of Mr al-Hilli's life to try to find a motive for the murders and also speak with his brother, named in reports as Zaid Hilli. Investigators have disclosed that Mr al-Hilli's brother has approached UK police to deny any feud with his sibling over money.
French police officers are now seeking help from Italian and Swiss investigators, as the region where the family were attacked is so close to those countries' borders.
