Cancer Patient Donation Jar Stolen From Convenience Store (VIDEO)

Police are currently on the hunt for a man who earlier this month stole a jar of money donated to help a women pay her cancer treatment bills from a suburban Chicago convenience store.

Police say the robbery happened just before 4 p.m. on Dec. 5 at Shop Mart, 13650 Cicero Ave., in Crestwood, Ill., the Chicago Tribune reports.

In a surveillance video released this weekend, a man is seen entering the store, making a purchase and, while the store clerk is turned away from the counter, grabbing the donation jar and leaving the store immediately.

The donated money was for Kelly Stawicki, an area woman who is battling stage 3 colon cancer. Stawicki is unemployed, uninsured and facing medical bills in the tens of thousands of dollars. Her family told CBS Chicago they were shocked by news of the theft.

"I'd tell him it's like the lowest thing you could do," Stawicki's aunt, Claudette Bernatowicz, told CBS she would say to the thief. "If your child was sick like that, how would you like it if somebody stole it?"

Anyone with information pertaining to the theft is urged to contact police at (708) 385-5131.
