GOLDEN, Colo. -- Jessica Ridgeway's killer, Austin Sigg, will spend the rest of his life in prison, a Jefferson County judge ruled Tuesday morning.
Sigg had no emotion on his face when the judge read his sentence -- life in prison on the charge of first-degree murder. Sigg was also given consecutive sentences up to 86 years in prison for other charges, including sexual assault and kidnapping. The sentencing, while technically including the potential for parole, essentially ensures Sigg will die in prison.
District Court Chief Judge Stephen Munsinger told Sigg, "I expect you to spend the rest of your natural life in prison," after he announced the sentence.
Sigg's mother, Mindy Sigg, was sobbing after the sentence was read. Sigg himself did not react.
Jessica's murder "was truly a reflection of pure evil," Westminster Police Chief Lee Birk said during a news conference.
Sigg pleaded guilty to kidnapping, killing and mutilating Jessica in October 2012. He later admitted to his mother he committed the crime and was arrested.
He pleaded guilty to 15 felony counts, including first-degree murder, in October this year. Sigg also pleaded guilty to attacking a female jogger in an unrelated case.
Sigg committed the crime when he was 17 making him ineligible for the death penalty.
Tuesday was the second of two days of testimony before the judge handed down his sentence. Sigg did not address the court during the hearing partly because of his age and partly because it would be recorded.
Prosecutors wanted Sigg to serve consecutive terms, meaning he would never leave prison. The defense wanted to the judge to allow Sigg's sentences to be served at the same time for all counts, potentially making him eligible for parole.
Members of Jessica’s family filled two rows in the courtroom. On Monday, Jessica's grandmother, Angie Moss, called Sigg a “monster” who “shattered the core of our family.”
Defense argued for leniency; says Sigg had mental health issues
Sigg showed signs of ADD and OCD as a child, his attorney said, but these issues were not addressed in any significant way.
The defense hoped the evidence about his mental health history showed Sigg was not in a sane state of mind when he killed and mutilated Jessica.
"We've tried to put our adult rational framework on his actions," a Sigg defense attorney said. "That's exactly what we can't do. We are not talking about someone who is developmentally an adult."
"He is someone who derives pleasure in pain. He derives pleasure in dismemberment," prosecutors said. "Any claim that this man lacked the executive function to plan and exercise a plan is proved false by his actions."
Prosecutors described kidnapping, murder

Chief Deputy District Attorney Hal Sargent described the nearly two hours that Sigg kept Jessica in his room after abducting her on Oct. 5 as she was walking to school.
"It's painful to imagine what he did to her in that time," Sargent said.
Jessica's mother was escorted out of the courtroom before Sargent spoke. Sigg's mother was hunched over and cried.
Sargent said Sigg strangled Jessica with zip ties but, as he later told police, he didn't have the leverage to stop her breathing. Sargent said he strangled Jessica with his hands for up to three minutes before she died. Later, when he saw her body twitching, Sigg placed Jessica in a bathtub with scalding-hot water and forced her face into it.
Jessica was then dismembered and her body parts separated. Sigg kept Jessica's skull and several of her organs. Other parts of her body were found in an Arvada field days after she was kidnapped.
"It's a chilling thought to think of what a fully matured Austin Sigg is capable of," Sargent said in asking for a life sentence.AlertMe
