Katrina Goss says she didn’t allow her 11-year-old son, Tysen, to date, and claims he knew she’d disapprove, so she claims the sixth-grader tried to hide his friendship with a girl two years his senior. Over a period of several months, she says she noticed the two would text and message each other on social media, and, she claims, occasionally meet up socially as well.

“It was really secretive and I didn’t know the extent of it, I guess,” says Katrina.

In a Dr. Phil exclusive interview airing Monday, the grieving mother claims both she and Tysen’s grandmother noticed his behavior changed. “He just seemed kind of distant, didn’t seem as happy-go-lucky as he normally was. He - he still did all of his things, all of his sports and was with all his friends and everything. But he just seemed kind of not very happy, just kind of sad in general.”

Katrina says she eventually contacted the girl’s family. “It did get to the point where I had to contact the parents and the guardian. And,” she claims,“they acted like they had no idea." 

On March 14, 2017, Tysen tried to commit suicide. Katrina claims this was after he’d read multiple posts that a 13-year-old “girlfriend” had committed suicide. She hadn’t – It has been reported that the girl was “playing a prank" Tysen was on life support for 21 days before he died.

The girl, who remains unnamed because of her age, was charged with malicious use of telecommunications service and using a computer to commit a crime. Both charges are misdemeanors. She could face time in a juvenile detention center if convicted.

Why does Katrina say she believes the older child’s actions crossed the line from a prank, into cyberbullying?
