Two girls, 12 and 14, arrested in Polk County, Florida after a girl kills herself because of bullying. Rebecca Ann Sedwick, 12, killed herself last December after being bullied by up to 15 girls and receiving text messages saying she should drink bleach and kill yourself. One of the girl’s posted a nasty message on Facebook saying she knew and did not care that Rebecca killed herself. Her parents are claiming her Facebook account was hacked and that she is a loving, caring girl.
