The two reconstructed the murder. They jumped the fence into Itamar, broke into an empty house, and stole an M-16 rifle, bullets and a bulletproof vest. Then they broke into the Fogel house, where they murdered the 11-year old Yoav and 4-year old Elad. Then they went into the parents' room where they fought with and murdered the parents. They apparently shot Ruti Fogel with the rifle.
Then they left the house, debated whether to return to look for weapons,returned, heard the baby crying and murdered her. They did not see the other children - they said they would have murdered them too had they seen them. They then stole an M-16 from the Fogel house as well.
They are affiliated with the 'Popular Front for the Liberation of Palestine.'
Their motivation was terror for the sake of terror. None of the terror organizations were apparently involved. All Israelis and Jews were their targets, and they came to murder - and for no other reason.
It took a long time for the two murderers to confess.
