PUEBLO — Authorities say a man considered a "person of interest" in a fatal crash near Cuchara in Huerfano County has turned himself in.

Colorado State Patrol Trooper Art Gumke says 25-year-old Ambre Cassio, of Pueblo, was killed when the pickup truck she was in went off the side of Colorado 12, crashed into a tree and rolled onto its roof late Saturday. The driver fled the scene.
