Michigan sixth-grader Tysen Benz was taken off life support April 4, 2017 - three weeks after the 11-year-old fatally injured himself in his own bedroom; reportedly in the mistaken belief that his 13-year-old friend had committed suicide. She hadn’t.

On Monday’s Dr. Phil, Tysen’s mom, Katrina Goss, claims a police detective told her the girl had “pranked” Tysen by allegedly faking her own death on social media.

After 21 days on life support, she says she made the choice to let Tysen go. “I don’t even know how to describe it. I don’t wish it on anyone or my worst enemy. It was - it was horrible,” says Katrina.

Weeping, she continues, “I mean he was so young. He was only 11. So to see a little child who was so innocent and had the most-- the brightest future -- to have to let him go was horrific.”

Katrina claims that the reported “prank” crossed over into cyberbullying. Why does she say his older brother now refuses to come home?
