SPARTANBURG, S.C. -- Charges have been upgraded against the son of a 104-year-old Spartanburg woman authorities said died from neglect.

The Herald-Journal of Spartanburg reported Thursday that George Leventis has now been charged with abuse or neglect of a vulnerable adult resulting in death.

Leventis was charged Dec. 4 with neglecting his mother after a home health nurse found Demetra Leventis lying in her own feces. She had fist-sized bed sores filled with maggots.

The mother was hospitalized for an infection, but the coroner said last week she died and conducted an autopsy.

It wasn’t known if George Leventis had an attorney or when he would have a bond hearing.
