What's the wildest deathbed confession you've heard as a nurse?

I’m not a nurse, but the most famous deathbed confession I’ve heard was probably 20 years ago or so. The Dr. That took the still famous photo of the Loch Ness Monster admitted decades later that it was a fake. He attached a toy dinosaur to a toy submarine. This pic is still used in stories about “Nessie” even though it’s a known fake.
