TINLEY PARK, Ill. -- People clam that a weird force seems to be taking over the Kohl’s parking lot in Tinley Park.

About 20 to 30 different shoppers could not get into their cars and appeared to be locked out.  Even their key fobs would not unlock the doors.

When cars were towed from the parking lot, everything worked fine.

"I went out there with the other key fob thinking that they key fob was dead, the battery was dead, and so we got the other one and I brought it out there and there was nothing," said Ken Hopman, mom's car disabled.

Five women were killed in that strip mall five years ago.

Police are not ready to blame ghosts yet. They say it is probably some kind of radio interference.
