The father of missing twin girls from Switzerland wrote a letter saying that he had killed his daughters before he killed himself, Swiss police say.
Police say the letter was dated 3 February, the day Matthias Schepp threw himself under a train in Italy.
He and the six-year-old girls were last seen on a ferry from mainland France to Corsica on 31 January but there has been no trace of the girls since.
Schepp failed to return them to his estranged wife at the end of January.
The girls' mother, Irina Lucidi, reported Alessia and Livia missing on 30 January, sparking a major international manhunt.
