Authorities continue search for missing twins

Police say their search for missing 6-year-old Swiss twins Alessia and Livia Schepp will continue two months after their disappearance.
Lausanne's prosecutor, Pascal Gillieron, told reporters Wednesday they have spared no cost in trying to determine what happened to the girls since they left their home in Lausanne with their father Matthias Schepp on Jan. 30.
Schepp killed himself in Cerignola, Italy on Feb. 3.
The girls' mother Irina Lucidi criticized Swiss police earlier this week and said she feared the search might be dropped.
Police say "the Corsica trail remains the primary one" despite authorities saying there's no formal proof Schepp brought the girls to the French island, before hurling himself under a train.
