“During the investigation, officers collected evidence of an individual regularly baiting a razor blade with peanut butter in an attempt to attract wildlife within the park,” the agency reported in a news release.

The news release said squirrels came in contact with a razor blade in a tree that McGrath had been observed baiting by officers conducting surveillance. Investigators didn't elaborate on what happened to the squirrels.
