Authorities in the northern Italian city of Lecco say they have arrested a mother who confessed to stabbing to death her three young daughters.

Carabinieri Col. Rocco Italiano said they arrested the mother, an Albanian national, after discovering the bodies of the three girls, ages 3, 10 and 13, Sunday morning.

Italiano said the parents had just separated, the father had departed Saturday for Albania, and the mother had no job. Italiano said, "There were economic difficulties, but not serious enough to justify this."

The family had been living in Italy for 13 or 14 years. Authorities were alerted by a neighbor who saw the mother in a state of confusion.
