Awwal 04, 1432 H/Feb 07, 2011, SPA -- Police were searching Lake Geneva by helicopter for missing Swiss twin girls whose father apparently committed suicide, AP reported. Swiss police said Monday they have no firm evidence where 6-year-olds Alessia and Livia have been since they were at the home of their father, Matthias Kaspar Schepp, in a Lausanne suburb on Jan. 30. Some 40 Swiss police investigators and French and Italian police were broadening the international hunt dubbed Operation Gemelle. The Canadian-born Schepp was separated from his Italian wife and is believed to have thrown himself under a train in southern Italy where his body was found by a railway station on Thursday night. -- SPA
