DALLAS (AP) — Investigators looking for how a Texas gunman obtained an assault-style rifle used in a Labor Day weekend rampage despite failing a background check have searched the home of a man they believe was involved in the "transfer" of the weapon, a federal law enforcement official said Thursday.
The official familiar with the investigation spoke to The Associated Press on condition of anonymity, citing a reluctance to publicly discuss the details of the search. The official said federal agents are investigating whether the Lubbock man has been manufacturing firearms but that there have been no arrests.
Spokespeople for the FBI and Bureau of Alcohol, Tobacco, Firearms and Explosives confirmed the agencies conducted "law enforcement operations" Wednesday in a residential part of Lubbock but declined to elaborate.
