A 22-year-old University of South Carolina student was caught on camera spitting and pouring chemicals into her roommates’ food in February, police said.

Hayley King is allegedly seen on camera pouring Windex into food in the off-campus apartment she shared with two other young women.

King’s roommates told police they set up multiple surveillance cameras after they began fighting with her.
