Swiss police comb lakeside in hunt for missing twins
Matthias Schepp threw himself under a train in southern Italy on Thursday having reportedly failed to return the six-year-olds to his estranged wife in the western Swiss lakeside village of Saint Sulpice on January 30.
Since then investigators have pieced together a trail of his movements through Switzerland, France and Italy, but with no sign of the girls, Alessia and Livia.
