A Colony High School student is behind bars, after Alaska State Troopers say he sexually assaulted a teen at the school last month.

Kaiden Jimenez, 17, made his first appearance Thursday in Palmer Superior Court, the day after he was arrested by troopers.

According to an online dispatch, troopers received an initial report Jan. 22. Charging documents against Jimenez state that the alleged offenses occurred on that date.

"Further investigation revealed that [Jimenez] had sexually assaulted and strangled a former girlfriend at the school," troopers wrote.

Jimenez, who is being charged as an adult, faces one count of third-degree assault, one count of first-degree attempted sexual assault and two counts of sexual assault.

Judge Frank Pfiffner says Jimenez is looking at serious prison time if he's convicted.

"On the first count, the attempted sexual assault, first degree, the potential sentence of that charge alone could be anywhere from 15-30 years, and a maximum fine of $250,000," Pfiffner said during the roughly 20-minute hearing.

Jimenez's mother and aunt attended the hearing, but did not want to discuss the case.

He remains held on a $75,000 cash performance bond and a $25,000 appearance bond. His trial is scheduled to start April 22.
