The video shows King spitting into multiple food containers, spraying Windex on food, and pouring the glass cleaner in food containers.

According to the report King and her roommates had "multiple altercations" in the weeks prior to the incident:

"The aftermath... caused me to fall behind in my classes," one of King's roommates said. "I was forced to switch out of one of my courses because I was so distracted with everything going on. This not only affected me physically, having to deal with the repercussions of the incident, but also mentally from the anxiety that came along with it."
