Victim says stabbing suspect wore clown mask

The victim, local WLS-TV reported, remained hospitalized this week and said a man stabbed her eight times in her leg and her arm. She also told the outlet he wore "a clown mask and gray hoodie."

"He came up to me so quickly that I didn't have a chance to run," Erika Gierczak told the outlet. "It was a big knife. I stood up with all the blood leaking from me on the floor, and I had still the right hand to call the police. The owners live upstairs, so they weren't able to help me."

Bartoli told USA TODAY there is no mention of a clown mask in the police incident report. 

A motive in the attack was not immediately known.

According to police, as of Thursday, the case remained open and no arrest had been made in the stabbing.
