A former high school teacher has pleaded guilty to having sex with a 17-year-old boy on the school's football team.

33-year-old Darcie Esson pleaded guilty yesterday to one count of sexual assault on a child by a person in a position of trust. Prosecutors dropped two other sexual assault charges as part of a plea deal.

Esson faces a sentence ranging from probation to an indeterminate life sentence without the possibility of parole.

Prosecutors say Esson had sex with the teen in a Glenwood Springs motel room in November while the Elizabeth High School football team was out of town for a playoff game.

Authorities say Esson's two young children and a teenage baby sitter were asleep in the room at the time.

The school is in Parker, about 135 miles east of Glenwood Springs. An arrest warrant affidavit says Esson had no official role in the team's trip.

School Superintendent Bob Neel says Esson resigned her teaching job in December.
