A British bomb disposal unit investigated suspicious items found at the home of a couple who were killed in an apparent execution-style shooting in France last week, police said Monday, CNN reported.

Police threw up a cordon around the home of Saad and Ikbal al-Hilli, who were killed along with Ikbal al-Hilli's 74-year-old mother in the French Alps. The al-Hillis' two daughters survived, one with wounds from a beating and a gunshot.

Officers sent residents away from their houses around the al-Hilli home in Claygate, Surrey, a wealthy town outside of London, police in Surrey County said.

But the items investigated by the bomb squad were not dangerous, and residents of the area were allowed to return, police said several hours later.

French and British authorities are still trying to determine who killed the four people and why.

Was it a robbery gone bad? A family feud over inheritance? A case of mistaken identity? Or, maybe, one of being at the wrong place at the wrong time?

Theories have abounded since investigators found the bodies.

About 25 shots were fired, police said.
