A 32-year-old teacher from Parker is under arrest, accused of having a sexual relationship with a high school student during a trip to Glenwood Springs.
Authorities say Darcie Esson is accused of felony sexual assault on a child by a person in a position of trust.
Investigators say Esson was a teacher at Elizabeth High School south of Denver last month when she accompanied the school's football team last month for a playoff game against Rifle.
The group stayed in Glenwood Springs.
Esson's bond is set at 25 thousand dollars.
