A 12-year-old Oklahoma boy was found with ligature marks on his neck on July 19 after taking part in the "blackout challenge," a dangerous trend circulating on TikTok wherein TikTokkers film themselves holding their breath or choking themselves until they lose consciousness. He was taken to the Oklahoma Children's Hospital for treatment but died early the next morning.
Tragedies like this one have led a group of parents to call on TikTok to let them see all the videos accessed by their children, to keep abreast of the dangers.
Parents are being encouraged by authorities to seek that information.
