An interesting article that has a neat feature: you can get a bio on any of the victims.
Don Christensen, a retired Air Force colonel who supervised prosecutors when Kelley was brought before a court martial, told NBC News he was convicted of fracturing the skull of his infant stepson.
Kelley was also convicted of assaulting his wife, Tessa, in the same incident in 2012, he added. The incident happened while Kelley was stationed at Holloman Air Force Base, New Mexico.
Apparently the U.S. Air Force did not enter his priors into the national database and he was able to purchase weapons regardless.
@Buorhann:
Trump says tighter laws may have prevented the citizen who shot Kelley from owning a gun. For once he got something right lol
