A 14-year-old South Carolina boy was found dead in a hotel room with his "incoherent" mother about a week after his estimated date of death, according to Greenville County officials.

Authorities found deceased Landon Chance Poston and his incapacitated mother on Monday while responding to a 911 call from an InTown Suites hotel in Greenville. 

"There were no obvious signs of physical injury noted to Mr. Poston. Mr. Poston's date of death is estimated to be November 14, 2022. An autopsy was performed on Mr. Poston on November 22, 2022," the Greenville County Coroner's Office stated in a media release. 

The Greenville County Coroner's Office confirmed to Fox News Digital that authorities had transported Poston's mother to an intensive care unit after finding her in the hotel room with her deceased son.
