This week, the medical examiner confirmed the remains were Tang.
The medical examiner said there is no evidence of foul play, and the sheriff's office is treating the case as an accidental death.
"After all these years, we have held out hope that Ms. Tang would be reunited safely with her family. Unfortunately, that did not happen," Cleveland County Sheriff Alan Norman told our newspaper partner The Shelby Star.
The initial search for Tang was frantic, and a massive sweep was conducted in the area, but nothing was found. Tang lived at the facility for 16 years until she disappeared.
Tang suffered from schizophrenia and had numerous medical issues. She often walked away, but was always quickly found.
The state forced Unique Living to close in 2009 amid the investigation into Tang’s disappearance. In 2011, Tang’s family settled a lawsuit with the owner of the facility.
“We know that the discovery of her remains will allow her family some closure,” Norman said.
