"We done paid for everything," Thompson said in the video.
When Thompson noticed the plywood over his mother's grave site, he lifted it to find his mother's casket exposed in a hole, WXIN reported.
"To me, it's not even deep enough," Thompson said in the video.
"To see her disrespected like that is wrong altogether," Thompson told WXIN.
Thompson said he spoke with the cemetery property owner, who told him they needed to move her, the television station reported. Thompson said no one had told him they were digging up her grave.
By Tuesday, crews had filled up the hole, according to WXIN.
"I mean that could be someone's kid, someone's family member in there just like it is my family member," Thompson told WXIN. "It is not right. It is wrong."
A cemetery spokesman told television station the headstone had been moved to the proper spot.
"The Carter family marker has been placed at the grave site as of July 2," the spokesman said. "However, as part of our commitment to all our client families, we guard their privacy and because of this, we do not discuss specific client matters with the media."
A spokesman for the Indiana Professional Licensing Agency told WXIN no administrative complaints against the cemetery have been filed with the State Board of Funeral & Cemetery Service.
