As part of its ongoing mitigation efforts, USU Public Safety has asked law enforcement partners to assist with further assessment of the room at the center of the evacuation of Mountain View Tower last Thursday, Jan. 16. Out of an abundance of caution, USU officials are clearing Mountain View Tower this evening at 6 p.m. before hazardous materials experts complete an inventory of items from the room. We anticipate residents will be let back in by 9 p.m. We realize this is a great inconvenience, especially with current outside temperatures. The following locations are available to students who are evacuating: the Junction, common areas in Canyon Crest and Central Suites, and the ballroom in the Taggart Student Center. Student Affairs will have pizza available in the Ballroom, and the Marketplace and the Junction will also be open. The Fieldhouse will also be available, with pickleball and basketball available. This is an ongoing mitigation effort, but law enforcement and environmental safety professionals expect that this will be the last time they will need to clear the building. Once the inventory and collection of items is complete this evening, the next action will be to restore the room (paint and replace carpet, etc.), which will have limited impact on most residents of Mountain View Tower. For students who experience academic or other impacts, please reach out to the CARE Team for support. Visit usu.edu/intervention/care-office for assistance and resources.We greatly appreciate everyone who has supported the residents of Mountain View Tower as they have faced numerous interruptions and additional stress over the last week. And we greatly appreciate your continued support.

Context

Background

On the evening of January 16, 2025, a hazardous materials situation at Utah State University's Mountain View Tower forced the evacuation of the entire dormitory in subzero temperatures. Student Joshua Peter Jager, 20, allegedly released hydrochloric acid gas throughout the first floor, covering it in a 'fog or vaporous substance.' The university reported that Logan Fire, hazmat teams, USU Police, and multiple USU entities responded to evacuate the building. KSL reported that campus police had found a cache of chemicals (including silver nitrate and potassium carbonate) in Jager's dorm room just three days earlier after he set off a fire alarm. Jager was arrested and charged with Class A misdemeanor causing a catastrophe and was banned from campus. The FBI Joint Terrorism Task Force joined the questioning but Jager denied any terroristic ideologies, stating he had 'made a mistake' by bringing chemicals to his dorm. The Herald Journal and Cache Valley Daily provided local coverage.
