RAPID CITY - A former New Underwood teacher has pleaded guilty to having sex with a 15-year-old student.

Kyle Keegan of Rapid City faces up to 15 years in prison when he is sentenced in March. The Rapid City Journal reports (http://bit.ly/10FEumo ) that he entered his guilty plea Tuesday on a charge of sexual contact with a child under 16.

In exchange for the plea, prosecutors agreed to dismiss a fourth-degree rape charge.

Twenty-six-year-old Keegan was arrested in October, five days after court documents indicate he had sex with the victim. He had taught social studies and was a guidance counselor at New Underwood High School when the allegations surfaced.
