Suspicious that something wasn’t right after “multiple altercations,” they decided to set up a hidden camera, NBC reported.
What they found upon viewing the footage was so shocking that King could end up behind bars for as long as 20 years.
Police say the footage — taken in February — shows the 22-year-old student opening the apartment’s refrigerator and spitting in several containers of her roommates’ food. She can also be seen spraying and pouring Windex in the food; the household cleaner can become deadly when ingested.
The footage, which has been uploaded to YouTube, appears to show King methodically contaminating the food. After opening containers, she appears to cock her head and spit multiple times into the food before carefully mixing the contents.
She returns to the refrigerator moments later with a bottle of Windex in her hand and begins spraying it onto the food. She repeats the process several more times and pours some of the cleaning solution into the food containers before reapplying the lids and placing them back in the fridge.
“The aftermath … caused me to fall behind in my classes,” one of King’s roommates said in a statement to NBC affiliate WIS. “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.”
The roommates, the station said, “did not want to be identified or talk on camera.”
After King’s roommates turned the footage over to police, investigators contacted King and asked her to come to the police station for questioning, according to ABC News. Under questioning, police said, King “confessed to the incident,” according to ABC.
She was arrested in February and charged with unlawful, malicious tampering with human drug product or food, according to the AP. The Class C felony charge carries a term of up to 20 years in prison following a conviction, according to ABC.
King was released after her arrest on a $5,000 personal recognizance bond, WIS reported.
Her lawyer didn’t respond to a request to comment, according to the AP.
The alleged criminality didn’t end with King’s arrest, according to her former roommates. Police said one of her roommates reportedly received a threatening text message from one of King’s allies.
“While Hayley is moving out don’t [expletive] with her,” the message said, according to WIS. “Y’all have been [expletive] taunting her since the semester started. If she tells me you’re [expletive] with her I will personally come and check you. You too old to try to be bullying some damn body. Grow the [expletive] up.”
King’s next court date is scheduled for June, according to ABC News.
