The owner of a funeral home in Colorado may have set up a side business selling body parts and used the proceeds to fund a trip to Disneyland, according to the New York Post in "Funeral Home Owners Allegedly Paid for Trip to Disney with Corpses teeth."
The FBI is investigating the funeral home.
It is possible that no laws have been broken. It is legal to sell human body parts for educational or research purposes.
Most states also allow funeral homes to sell items that are taken off of human remains. It is possible the FBI is investigating something else or an issue that is only remotely related to what the media is reporting.
Even if what the funeral home was doing is technically legal, it can still be considered unethical, if families were not informed about the home's practices.
