An Oklahoma woman was fatally shot in the head by her 3-year-old son who came across a handgun in their Tulsa home, police said on Tuesday.
The victim, a 26-year-old Army veteran, died on Monday and was apparently hit with a single shot as she was changing her 1-year-old daughter's diaper. The victim's grandmother, who lives in the house, found the woman along with the children inside the house, police said.
