Colorado Teen Confesses to Abducting, Killing 10-Year-Old

Lived a mile from Jessica Ridgeway

Prosecutors say a Colorado teenager has confessed in the abduction and killing of a 10-year-old girl and in a separate attack on a runner.

Authorities also said Thursday they have "overwhelming" DNA evidence against 17-year-old Austin Reed Sigg.

Sigg lived about a mile from Jessica Ridgeway, who disappeared Oct. 5.
