Rose, the four-year-old child from Netanya who has been missing for over two months, was murdered by her grandfather, who put her body in a suitcase and dumped it in the Yarkon River, police announced Tuesday. The girl was the daughter of a French immigrant couple that got divorced in 2007. The mother has been living in Israel and began building a new family with her ex-husband's father. The mother, Marie Pisam, has already given birth to two babies fathered by Rose's grandfather. While Rose went missing in May 2008, information about her disappearance reached the police only a number of weeks ago. Rose's Franco-Israeli family had a convoluted history from its inception. In the late 1980s, a young Frenchwoman named Elizabeth got pregnant and decided to leave Israel for her native country to raise her child away from his father. The child's name was Ben. By the age of twenty, Ben made the decision to travel to Israel along with his girlfriend Marie and their little girl Rose, to meet Ben's biological father. But as things turned out, his father Ronnie Ron had a greater interest in getting to know Marie than in becoming acquainted with his own son and granddaughter. Before long, a new couple was formed. Marie and Ron remained in Israel as Ben went back to France, taking Rose with him. Later, Marie and Ron convinced Ben to let Rose join them in Israel. Rose returned, but not, however, to live with her mother and grandfather, but rather with her great-grandmother, Viviane (Ron's mother). Since May 12th, when Ron went to his mother to pick up his granddaughter, none of the family members seemed to know what became of the little girl, and Ron told everyone that he had simply sent her back to France. It took over three month before Viviane contacted the Child Protection Center in Jerusalem - which in turn immediately called the police. Marie and Ron have both been arrested and were remanded in court on Tuesday. Viviane, the great-grandmother has been put under house arrest and is also a suspect in the case. During his interrogation, Ron admitted to killing Rose. He said he had slapped her in the face and killed her by accident. He then put the little girl in a suitcase which he threw in the murky waters of the Yarkon River. Later he changed his version of the events and denied that he had killed Rose. Police still haven't found the body. The gruesome details of the affair were initially published by the French daily Le Parisien on Tuesday, while a police gag order still prevented the Israeli media from providing the details.
