Waller says an employee told her it was the third razor blade that someone turned in that same day.
KOKI reached out to Walmart's corporate office for a comment.
A spokesperson for the company released this statement:
"We're dumbfounded that someone would do this in our store; this is appalling. We have checked all of our shopping carts and are continuing regular checks. Additionally, we are reviewing our surveillance footage in the hopes of identifying who did this so we can alert police and prevent this from happening elsewhere."
