A 17 year old Jackson Hole High School Student has been arrested under suspicion of being involved with the posting of a threat of a shooting to take place Friday at the school. Undersheriff Bob Gilliam told a news conference Thursday evening that the case was being handled as a criminal investigation. He explained that the young man was connected to the area where the threat was left within the school and that led investigators to interrogate him. In the process, Gilliam says, the student provided very specific information about the threat leading them to believe that he in fact may have been the one who made the threat. However, Gilliam declined to give any further details about the threat itself. Gilliam says the threat was discovered by another student and reported to staff about 11:45 am Thursday. Gilliam says security at all Teton County Schools will be very tight throughout the day Friday. He says there will be increased police presence around all Teton County schools in the coming days, and the campuses will be closed during lunch and other times students typically come and go. Superintendent Pam Shea emphasized that the incident is being handled jointly by the Teton County Sheriff’s Office, the Jackson Police Department and the school district; and she assured the district’s priority is the health and safety of all of the students, teachers and other personnel who work with the students on a daily basis.
