TIJUANA, Mexico (AP) -- State authorities in Mexico say a 19-year-old Russian woman has confessed to killing and mutilating her mother and sister.
Baja California state deputy prosecutor Jose Maria Gonzalez says the woman was detained Friday afternoon in Tijuana.
Officials say the woman identified as Anastasia Lechtchenko told police that she'd killed the two because they practiced witchcraft against her.
The dismembered bodies of the 45-year-old mother and 12-year-old sister were found June 10 in plastic bags at their house in Playas de Tijuana, less than a mile (almost 1 kilometer) from the U.S. border.
A judge is set to decide whether there is sufficient evidence to prosecute the woman.
