Arizona law enforcement alleges that an 18-year-old killed his mother and tried to report her as kidnapped to cover up her death. Less than 10 minutes later, the son of Mary Collier, 38, called 911 to report her supposed kidnapping. The Pinal County Sheriff’s Office said its deputies quickly confirmed that the body was Collier’s. Her son who made the call was identified as the suspect in her death, the sheriff’s office said. Lt. Ross Teeple of the sheriff’s office told KPNX that the cause of death appears to be “edge weapons” and blunt-force trauma.
