CAIRO (AP) - Egyptian investigators say all but one of the 21 victims of the New Year's attack on a church in Alexandria have been identified.

A security official said Monday the investigation into the identity of the perpetrator is now focusing on this final person's remains, including a severed head.

Typically in suicide bombings, the head of the attacker is flung away by the blast but remains in one piece.

Investigators believe a suicide attacker carried out the bombing on the Saints Church in Alexandria as worshippers were emerging from midnight mass.

Following DNA tests, the official said three of four remaining unidentified bodies were revealed to belong to women missing since the attack.

He spoke on condition of anonymity because the investigation was still under way.
