(DENVER) -- The teenage suspect in the murder and dismemberment of 10-year-old Jessica Ridgeway will stand trial after a judge ruled there is enough evidence, including an alleged 911 confession, to move forward with the case.
Prosecutors played the 911 recording on Friday at a preliminary hearing for Austin Sigg, 18, in which the teen confessed to murdering the fifth grader and trying to kidnap a female jogger.
"I murdered Jessica Ridgeway, I have proof that I did. I'm giving myself up completely, there will be no resistance whatsoever," Sigg said on the Oct. 23, 2012, recording, according to ABC News Denver affiliate KMGH-TV.
The dispatcher then asked about his criminal history.
"The only other [incident] was Ketner Lake, where a woman was attacked. That was me," Sigg said in the recording.
A lead investigator on the case testified that Mindy Sigg, the teen's mother, told the dispatcher her son had hidden Jessica's remains in a crawl space under the family home, KMGH reported.
Authorities arrested Sigg at his Westminster, Colo., home that evening.
Sigg is charged with murder, kidnapping, sexual assault and robbery in the Ridgeway case.
He faces an attempted kidnapping charge for the May 28, 2012, attack on a 22-year-old female jogger. Police said a man tried to grab her from behind on a trail around Ketner Lake.
The woman said the man tried to put a rag over her mouth that had a chemical smell. She was able to get away and call 911.
A judge ruled Friday that Sigg should be held without bail. He is scheduled to be arraigned March 12.
