Hobson — whose married name was Hackney but who went by her maiden name — was arrested along with her two adult sons in Maricopa and charged with dozens of counts of child abuse. She pleaded not guilty to the charges.
It was not clear what led to Hobson's death. According to NBC affiliate KPNX in Phoenix, Hobson had suffered a brain injury while in custody and as a result, was deemed unfit to stand trial in August. She had been in a medical facility receiving treatment after the injury, KPNX said.
A phone call to the Pinal County Sheriff's Office seeking more information about the circumstances of Hobson's death was not immediately returned.
