The remains of different individuals are never intermixed, and fireproof serial number tokens are placed with the body before it’s cremated and remain with the ashes through delivery if verification is needed.
Never is a bold statement. There was a funeral director in my small home town that was found guilty of charging people for services and then not delivering on them. A looot of money was involved. While obviously not the same thing, I don’t have a hard time imagining his laziness and greed getting shit mixed up.
The important thing is to remember them, regardless of the contents of the urn, right?
Sure, but you can do that for free.
Taste it. It’s the only way to know for sure. Ofc, this is most helpful if one was forward thinking enough to have already taken a sliver of them during life, charred it, and then tasted that. It’s kind of hard to compare without that data point, but, depending on how well one knew the subject, it might still be possible.
Taste test.
