Awwal 03, 1432 H/Feb 06, 2011, SPA -- Police in Italy, Switzerland and France searched on Sunday for 6-year-old twin girls who disappeared after their father died in an apparent suicide. The body of Matthias Kaspar Schepp, 43, a Canadian-born resident of Switzerland, was found by a railway station near the southern Italian port city Bari shortly before 11 p.m. on Thursday, AP cited Swiss police in the canton (state) of Vaud as saying. Authorities believe Schepp, who was separated from his wife, threw himself under a train. Police in Switzerland, Italy and France are searching for the twin girls, Alessia and Livia, who lived in Lausanne with their mother, Irina Lucidi, 44. According to Italian news reports, Schepp picked up his daughters from their mother's home on Jan. 28 for the weekend. Swiss police say Schepp, rather than returning the girls to their mother, took them when he left his home in St. Sulpice, a suburb of Lausanne, on Jan. 30. Both girls were described as wearing glasses and blue jeans, with Alessia bundled in a white jacket over a striped shirt, and Livia dressed in a purple ski jacket over a green t-shirt. Swiss authorities say they alerted all European police that the girls were missing on Jan. 30. Swiss police say an initial investigation has determined that Matthias Schepp, also blond-haired and wearing glasses, drove the girls in a Swiss-registered Audi A6 through Annecy, France, on Monday and on to Marseille on Tuesday. After leaving Lausanne, Schepp turned up in Marseille and Toulon, France, before showing up in Italy, Italian police official Alfredo Fabbrocini said. «There's a gap of a few days,» Fabbrocini said, adding that police were trying to track down the man's movements through cash withdrawals, CCTV, witnesses and phone calls. Authorities have urged anybody with information to come forward. The search has included helicopters and dogs, according to ANSA, the Italian news agency. A Facebook page set up to find the girls invites people with information to make contact.
