LONDON (AP) -- Police are searching for a second day the U.K. home of a British-Iraqi couple killed along with two other people while vacationing in the French Alps.
The search of Saad and Iqbal al Hilli's home in the village of Claygate, a London suburb, is part of a French-led investigation into the case. The couple and the two other people were each shot twice in the head. The couple's two young daughters survived, with one in a medically-induced coma for her wounds.
Police on Sunday continued their examination of the house in Claygate, with Surrey police confirming two firearms officers visited the scene.
French investigators also are in Britain for what prosecutors have warned will be a long and complex probe about who carried out the killings and why.
