The 81-year-old was observed trying to put the animal in a box, but had some trouble since the animal was "still twitching."
TenPas then unleashed another flurry with his tire iron before managing to get the animal inside the box.
For his part, TenPas told the newspaper he has "police powers" - a claim that has since been refuted by town officials.
Besides, the safety-first alderman claims, the raccoon may have been showing signs of rabies.
"It's not like a citizen doing it, but when somebody calls me, I come," TenPas said. "I take care of problems. Why do you think I've been alderman for 40 years?"
From here, we can honestly say, good question, Larry TenPas. Because we honestly don't know. The alderman will not be charged with animal cruelty in the wake of the raccoon bludgeoning.
