A former night manager at a Casper boys' home accused of providing marijuana to teenage residents would serve at least two to four years in prison under a plea agreement made public Thursday.

As part of the agreement, Roger Dean Peters, 47, pleaded guilty to delivery of a controlled substance to a minor and marijuana possession. The District Attorney's Office dismissed seven other charges against him.

Prosecutors also agreed to recommend he serve no more than seven to 10 years in prison. The defense, in turn, will ask for no less than a two- to four-year prison sentence.

The delivery charge carries a maximum prison sentence of up to 20 years.

During a brief hearing in Natrona County District Court, Peters admitted to giving a joint to an underage person who was not identified. In earlier interviews with police, Peters denied providing marijuana to residents of the boys home.

According to police, five teenage residents at the R.L. Mills Home for boys in August told investigators Peters gave them marijuana while he was working there. The teens said he'd given them marijuana once at R.L. Mills and another time at his Casper home.

The R.L. Mills Home serves boys ages 12 to 17. They are court-ordered to live there for a variety of reasons, including anti-social and criminal behavior.

The allegations came to light after another employee at the home overheard two residents talking about getting marijuana and cigarettes. The home investigated the matter and found that some of the boys said Peters had been supplying them with marijuana, according to police testimony during Peters' preliminary hearing last year.

Peters resigned from his job at the home due to the case. He remained held Thursday at Natrona County Detention Center in lieu of $50,000 bond.
