As horrific details of the alleged rape and assault of a Tennessee high school basketball player by three teammates emerged, three school officials in Tennessee were expected to appear before a Chattanooga juvenile court judge Thursday to answer charges that they failed to report the incident.

Coach Andre Montgomery, assistant Karl Williams and Athletic Director Allard “Jesse” Nayadley are accused of failing to report a sex crime involving a minor, which is a class A misdemeanor. In addition, three juvenile members of the Ooltewah High basketball team face charges of aggravated rape and aggravated assault and ultimately could be tried as adults.

The incident involving the suburban Chattanooga team occurred in a rental cabin during a Dec. 19-23 trip to a tournament in Gatlinburg, which is about two hours from Chattanooga. Both Montgomery and Williams were in the cabin when the alleged rape occurred, according to documents obtained by ESPN’s “Outside the Lines.”

A freshman player allegedly was so severely raped and assaulted with a pool cue that he suffered a punctured colon, bladder and prostate. ESPN notes:

According to the police report of the incident, two 16-year-old sophomores and a 17-year-old senior member of the team had locked the door to a downstairs bedroom and overpowered the freshman, wrestling him onto the bed.
All three of the teens admitted to their roles in the attack, according to the report.
One of the 16-year-olds told police that he held his freshman teammate down on the bed by lying across his back, while the other 16-year-old held down his teammate by the hips.
The 17-year-old then pressed a pool cue against the freshman’s clothing with so much force that it broke through the teen’s clothing and penetrated his rectum, according to the police report.
The 17-year-old told an investigating officer that he “accidentally” used too much force and later described the alleged assault as “horseplay.”

It is unclear what the coaches, who were one floor above the players, might have heard or known. The remainder of the basketball season has been canceled and Montgomery, Williams and Nayadley were suspended without pay. If they choose to plead guilty, they would face a fine of no more than $2,500. If they plead not guilty, a grand jury would be empaneled.
