Police in Switzerland looking for missing twin girls whose father apparently committed suicide have searched Lake Geneva.
They said they had no firm evidence where six-year-olds Alessia and Livia have been since they were at the home of their father, Matthias Kaspar Schepp, in a Lausanne suburb on January 30.
Some 40 Swiss, French and Italian police are broadening the international hunt dubbed Operation Gemelle.
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 station last Thursday.
French police say Schepp bought three ferry tickets from Marseille to Corsica but it is not clear if any were used.
