Kathleen Edwards, the 9-year-old Michigan girl who made headlines when she was cyber-bullied for having Huntington's disease, has died, according to news reports.
Edwards' mother, Laura, died of the same disease in 2009, CBS News reported.
Kathleen was the subject of bullying by neighbor Jennifer Petkov, who the Daily Mail reports posted Facebook photos that show Kathleen's face over crossbones, and Laura's face lying next to the Grim Reaper. Petkov also drove around a truck with a coffin attached in front of Kathleen's home, CBS News reported.
CBS Detroit reported that Kathleen had pneumonia, which is especially dangerous for people with Huntington's disease.
Huntington's disease is a neurodegenerative disease, where nerve cells waste away in parts of the brain, according to the A.D.A.M. Medical Encyclopedia. It's caused by a genetic defect, where a section of DNA repeat many more times than it is supposed to.
