Authorities say a Florida woman fatally shot her mother when she accidentally discharged a gun that one of her teenage children brought into their home in suburban Tampa, the AP reports. Hillsborough County sheriff's investigators say the woman had taken the gun away from the teen and unloaded it early Friday morning. According to the Tampa Bay Times, the woman thought the gun was empty but there was still one round in the chamber. She accidentally fired the weapon, hitting her mother, 52-year-old Carolyn Wright. Wright died at the scene. Investigators say one of the teens living at the home panicked and tossed the gun into a storm drain. Deputies recovered the weapon. They don't know where the teen got the gun. (More guns stories.)
