Man with mental and physical disabilities buys gun, unintentionally shoots and kills himself

24-year-old Jonathan Smith, of Limestone County, Alabama, had recently purchased a handgun. On Friday he took a gun-safety course, on Sunday he unintentionally shot and killed himself.
According to news reports, Smith "had mental and physical disabilities" including having multiple sclerosis and attending special education classes in high school.
According to the sheriff, "It was an accidental shooting. He was playing with the gun when it discharged, striking him in the chest."
Because of Alabama's weak gun laws, Smith had been able to obtain a concealed weapons permit for the gun. He only had the gun a few weeks before the shooting.
