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 on her way to school.  Her dismembered body was found five days later in a nearby field in the town of Westminster.

Sigg made his first court appearance Thursday, keeping his head bowed for much of the time, talking with his attorney but otherwise saying little.

He made eye contact at one point with relatives of Ridgeway, who were in the courtroom wearing purple ribbons in the girl's memory.

Sigg was taken into custody Tuesday night. The suspect's mother says she called police and her son then turned himself in.

Police say they also expect to file charges against the suspect in connection with a separate case that involved an attempted abduction.

Back in May, a 22-year-old woman told police a stranger tried to grab her from behind while she was jogging.
