Two Chicago sisters are behind bars after they reportedly stabbed a store security guard 27 times -- because he asked them to put on masks and use hand sanitizer.
Jessica Hill, 21, and Jayla Hill, 18, were ordered to be held without bond Tuesday, two days after the attack occurred, prosecutors say.
After the 32-year-old guard made the request, Jayla punched him, says Chicago PD spokeswoman Karie James.
Jessica then pulled out a knife and began stabbing him while Jayla held him by his hair, James says.
The guard is currently in critical condition, according to prosecutors.
Why do some people get so angry when they're asked to wear masks?
