EAGLE, Colo. -- A former Eagle County high school student admitted Wednesday that he sexually assaulted two classmates in 2003 and his mother said he wants to join the Marines, the Vail Daily News reported.

The 17-year-old boy, who was not identified because of his age, reached a plea bargain with prosecutors and will be sentenced on Sept. 12.

He was released to his parent's custody after the guilty plea and was ordered to undergo a psychosexual evaluation before sentencing.

His mother said he is getting close to obtaining his GED and wants to join the Marines, the newspaper said.

The teenager could be sentenced to two years in juvenile custody and must register as a sex offender.

The two assaults did not occur at Battle Mountain High School, prosecutors said. One girl told police the boy raped her at her home. The other girl told police that she was raped at his home. The assaults occurred in June and October 2003.
