In the wake of the Sutherland Springs church shooting , in which the gunman , 26-year-old Devin Patrick Kelley of nearby New Braunfels killed 26 and injured 20 others , the Fix NICS Act of 2017 was introduced in the 115th United States Congress . Kelley was prohibited by law from purchasing or possessing firearms and ammunition due to a domestic violence conviction in a court-martial while in the United States Air Force . The Air Force failed to record the conviction in the Federal Bureau of Investigation ( FBI ) National Crime Information Center database , which is used by the National Instant Check System to flag prohibited purchases . The error prompted the Air Force to begin a review . The attack was the deadliest mass shooting by one person in Texas and the fifth-deadliest mass shooting in the United States
