Police have announced they are expanding their search for the body of 4-year-old Rose, the little girl who was allegedly murdered by her grandfather four months ago.

After an extensive search of the Yarkon River by divers turned up empty, despite a confession by Rose's grandfather in which he said he had tossed her body into the river in a suitcase, searchers continued their efforts in the Sharon region, but with no success Thursday afternoon.

Police said early Thursday evening they would extend the search to the area south of Netanya and the Netanya shoreline. Meanwhile, Rose's mother, married to her grandfather, was questioned again Thursday as well.
