Dallas (AP) – According to a court document, a 7 year old Dallas girl whose mother was recently arrested in her death was stabbed more than 30 times. Madison Petry died after being stabbed on Thursday. Twenty three year old Troyshaye Mone Hall faces a capital murder charge in her daughter’s killing, as well as a charge of aggravated assault in the stabbing of a 16 year old boy. An arrest warrant affidavit says Hall’s mother and brother tried to take the knife from her after her brother’s friend was stabbed, but she got away from them and stabbed her daughter in an apparent killing frenzy.
