A college student is facing felony charges after a hidden camera allegedly showed her spitting and pouring cleaning fluid in her roommates’ food.

The video — recorded on February 4 — appears to show University of South Carolina student Hayley King, 22, taking food belonging to her two roommates out of a refrigerator and contaminating it, NBC affiliate WIS reported.

King’s roommates set up the camera after “multiple altercations” with the suspect caused them to fear what she was doing while they were not home, according to an incident report.
