Austin Sigg, Colorado Teen Accused Of Killing And Dismembering Jessica Ridgeway, Pleads Guilty

Teen Pleads Guilty To Killing, Dismembering Colorado Girl

Against the advice of his attorney, the teen accused of kidnapping, killing, sexually assaulting and dismembering 10-year-old Jessica Ridgeway has decided to plead guilty to all charges.

In front of a packed courtroom on Tuesday, a Colorado judge accepted the guilty plea of Austin Reed Sigg, 18, in both Jessica's case and a previous attempted kidnapping case involving an unnamed female jogger at Ketner Lake in Westminster.

The plea deal comes after Sigg initially entered not guilty pleas despite early media and police reports that he'd confessed to both crimes.

Jessica, a fifth-grader, disappeared from her home almost exactly one year ago on Oct. 5 while on her way to school. Just days after she was kidnapped, authorities found Jessica's backpack abandoned in a suburb in nearby Superior and then on Oct. 10, her torso was found inside of a black trash bag discarded in a secluded park.

It wasn't until about a week before Halloween that authorities received a 911 call from Sigg's mother.

"I made the phone call, and he turned himself in. That's all I have to say," the then-17-year-old's mother Mindy Sigg told The Associated Press.

On the 911 call, Sigg could be heard telling the dispatcher, "I murdered Jessica Ridgeway, I have proof that I did. I'm giving myself up completely, there will be no resistance whatsoever."

When officers arrived, they took Sigg's confession and were told that some of Ridgeway's remains could be found in the crawlspace of the home he shared with his mother. Authorities say Sigg's DNA was found on Jessica's clothing, and that he described abducting her as she walked past his car. According to police, Sigg bound her legs and arms, drove around for a while and then took her to his house where he strangled her and dismembered her body in the bathtub.

When he was asked by the 911 dispatcher about his criminal history, Sigg said, "The only other thing that I have done was the Ketner Lake incident where the woman got attacked. That was me."

Sigg lived within one mile of both Jessica's home and the lake where the female jogger was attacked.

An investigator later testified that Sigg had used a homemade chloroform recipe that he found on the internet to try to subdue a woman, and additional testimony revealed that child pornography was seized from Sigg's laptop.

At the time of his arrest, Sigg was enrolled at Arapahoe Community College.

Since Sigg was legally a minor when the crime was committed, he is not eligible for the death penalty, according to Colorado law.

Sigg faces a sentence of life in prison with the possibility of parole after 40 years.

CORRECTION:An earlier version of this article stated that Sigg was enrolled in Arapahoe Community College's mortuary science program after a classmate said he identified the program as his major. However Sigg hadn't completed preliminary coursework that would have allowed him to enroll in the program.
