A man who was sentenced to life in prison without parole as a juvenile was resentenced Thursday as part of the state’s response to a U.S. Supreme Court decision that found the life sentencing of teenagers who committed murder unconstitutional.

Christopher Weedman was sentenced to life in prison without parole for the 1996 first-degree murder and sexual assault of a 13-year-old girl. He was 17 at the time. Now 38 years old, Weedman was resentenced to 40 years to life, making him eligible for parole after serving 40 years, according to the Adams County District Attorney’s Office.

Weedman is one of 48 Colorado inmates who is being resentenced following a 2016 U.S. Supreme Court decision.

Adams County District Judge Thomas Ensor, who presided at Weedman’s original trial, handled the resentencing.

“I feel so sorry for Tiffany and the horror she must have felt on that day,” Ensor said in a statement.

A teacher found Tiffany Boelter dead on the grounds of Dupont Elementary School in Commerce City on Halloween in 1996. She was partially clothed. Her throat and wrists were slashed and she suffered multiple stab wounds.
