What should have happened?

An
***TRIGGER WARNING*** so I'm watching this episode of Dr. phil about the 11 year old boy who committed suicide recently. His 13 year old girlfriend had pranked him and pretended like she committed suicide and had her friend text the boy that it was real. A few minutes later, the 11 year old hung himself and later died due to his injuries. The girl was charged with minor things. What do you think should have happened to the girl? Should she have been charged with his death? Not charged at all?
