Two sisters who stabbed a store guard 27 times for asking them to wear masks will be held in jail without bond pending trial.
The 32-year-old victim is hospitalized in critical condition, a police spokeswoman told ABC News.
Jessica Hill, 21, and Jayla Hill, 18, were arrested at the scene of the bloody attack and both were treated for lacerations on their hands.
The incident took place at Snipes shoe store on Chicago's West Side on Sunday evening. The sisters entered the store and were asked by the guard to wear masks and use hand sanitizer placed at the front of the store for incoming customers.
But the women refused both requests and an argument ensued. One of the sisters began filming the 6-foot-5, 270-pound security guard on her mobile phone, prompting him to grab the phone.
Jessica Hill hit the guard with a trash can and punched him in the face. She then allegedly pulled a knife from her back pocket and stabbed the victim repeatedly while Jayla Hill held him by his hair.
He managed to break free and -- despite his many wounds -- was able to hold both sisters until police arrived.
The incident was captured on the store’s security cameras, according to the Chicago Sun-Times.
The victim was stabbed 27 times in his chest, back and arms.
During Tuesday's bond hearing, the women's court-appointed attorney said the stabbing was "self-defense," adding both women suffered from bipolar disorder.
