A South Carolina mother says her 11-year-old son died playing a game in which people challenge each other online to choke themselves until they pass out.

Latrice Hurst says in a statement released through her pastor that her son, Davorius Gray, was playing the "pass-out game" before he died last week.

Hurst says she wishes she had monitored her son's use of social media more carefully. She says her son had not been depressed and described him as "a prankster and loved to play tricks."

The Spartanburg County Coroner's office and local police are investigating the death. Coroner Rusty Clevenger says an autopsy report has not been completed.

The story was first reported by WYFF-TV.
