BARRON, Wis. (WSAW/CNN) -- "You are the embodiment of pure evil," the Barron County judge told Jake Patterson Friday during the sentencing.
The 21-year-old man convicted of killing the parents of a 13-year-old girl and held the teen hostage for 88 days was sentenced to life in prison Friday without the chance of parole.
In a victim statement from Jayme Closs, read by her attorney, Closs wrote, "Jake Patterson will never have any power over me. I feel like I have some power over him because I get to tell the judge what I think should happen to him. He stole my parents from me. He stole almost everything I loved from me. For 88 days he tried to steal me and he didn't care who he hurt or who he killed to do that. He should stay locked-up forever."
Jayme Closs' relatives spent three months agonizing over the Barron County teenager's whereabouts before she escaped from the man who'd gunned down her parents and imprisoned her in a remote cabin.
Patterson was sentenced in a Barron County court in northern Wisconsin after pleading guilty last month to two counts of intentional homicide and a count of kidnapping. The sentencing hearing lasted two hours as siblings of James and Denise Closs gave victim impact statements. Jayme Closs was not in the courtroom. Jayme's uncle read a statement as well.
"For this monster, Jayme won't have her mom and dad at her dance recitals. Won't have her mom and dad at prom, or come and dance. My brother won't be able to walk down the aisle her wedding day."
Patterson shot and killed James and Denise Closs early Oct. 15 at their home outside Barron with the intent of kidnapping their only daughter, whom he'd noticed by chance just days earlier at a bus stop.
He dragged the girl from the bloody crime scene into his car's trunk and drove off, setting off a massive search.
Authorities say he held Jayme captive in his cabin some 65 miles to the north until January 10, when the middle-schooler escaped and flagged down a woman walking a dog.
"You are one of the most dangerous people to walk this planet," the judge told Patterson after Patterson interruped the judge near the end. Patterson was seen visibly shaking his head 'no' while the judge spoke.
She is now living with an aunt and uncle, and has only recently appeared at public events celebrating her.
"Today was a very important step in the process of helping Jayme move forward," her aunt Jennifer Smith said. "We are satisfied with the outcome and believe that it will give Jayme some much needed piece of mind."
Patterson attorney's said his only offense prior to the case was a traffic citation from Rice Lake.
