State and federal prosecutors worked together to bring felony charges against Sean Michael Warner for his role in the drug death of a 14-year-old girl in 2011.

Tuesday, Warner turned down his right to have a jury decide whether there was enough evidence for a trial. Instead he plead guilty as part of a plea deal.

"We feel this is a win win," said Assistant U.S. Attorney Kim Sayers-Fay. "It saves the taxpayers a lot of expense and it gets a good just outcome."

Sayers-Fay recommends Judge Sharon Gleason sentence Warner to 13 to 18 years in prison for drug trafficking that resulted in death. Gleason has the power to increase the sentence to 20 years or go lower than 13 years.

Warner has no criminal history according to Sayers-Fay.

The victim, Jena Dolstad, died of a heroin overdose according to police. Warner admitted to giving her the drug that ended her life.

Due to the case being prosecuted at the federal level Sayers-Fay says more than one person can be held responsible for the minors death. Max Raymond Jewett faces felony charges for dealing the drug to Warner, that Warner gave to Dolstad.

"Everybody who's responsible for trafficking of drugs that eventually result in death of serious bodily harm to a person ought to be held responsible," says Sayers-Fay.

Sentencing is scheduled for February 11, 2015.
