A man is behind bars in Garfield County after he allegedly buried his mother’s body in a coal bin at their Panguitch home.

Police found the 90-year-old woman’s body Wednesday “buried under a large amount of coal in the coal bin of her home” more than two weeks after she reportedly died, a news release from the sheriff’s office said.

Her 66-year-old son, who lived with her at the time, was booked into the county jail later that day, said sheriff’s office spokeswoman Denise Dastrup.

The woman’s granddaughter tipped off law enforcement when she took a letter from the man, her uncle, to a law enforcement agency in St. George. The letter stated that her grandmother had passed away on Dec. 25, and that the uncle had “taken care of the body.”

The man is being held in lieu of $200,000 cash-only on suspicion of abuse or desecration of a human body and failure to report the finding of a dead human body, Dastrup said. Charges had not been filed as of early Thursday.
