One of the three young men responsible for a 2009 murder in Sheridan was given his new sentence Wednesday.
Three years ago Wyatt Bear Cloud pled guilty to his part in the murder of Sheridan businessman Robert Ernst.
Bear Cloud, who was 16 at the time of the murder, was sentenced to life in prison.
But last year the U.S. Supreme Court outlawed mandatory life sentences for juveniles.
"This is new for everyone around the country and people are kind of finding their way," said Sheridan County Prosecutor Matt Redle.
Judge John Fenn sentenced Bear Cloud to life in prison with parole eligibility after 25 years, which is exactly what a new Wyoming State law calls for in this situation.
"It set the number of years that the judge wanted to use before you would be eligible for parole consideration and that was the 25," said Redle.
Bear Cloud was also originally sentenced to 20 to 25 years for stealing the gun used to kill Ernst, and 20 to 25 years for burglarizing Ernst's home.
Judge Fenn ruled Bear Cloud must serve the gun theft sentence before serving the murder and burglary sentences concurrently.
"I wasn't sure whether or not Judge Fenn would maintain the consecutive nature of the murder charge following the aggravated burglary charge, which was the theft of the gun. It would have been easy for him to have said, 'No, I'm just going to run the murder charge concurrent with everything,'" said Redle.
Bear Cloud's attorney asked for all sentences to run concurrently and parole eligibility after 20 years.
With good behavior Bear Cloud could get parole in about 35 years.
Dharminder Vir Sen, who pulled the trigger and was 15 at the time of the murder, will have a resentencing hearing in late October.
