Mendoza said there was nothing memorable about the purchase from Aghdam. White House Press Secretary Sarah Sanders previously told Fox News that the president was briefed and they were monitoring the situation. "They said, 'Don't worry about, '" Ismail said. Sharan Aghdamhas stated that "they didn't do anything and she got killed and three or four more people got hurt". Caldwell declined to identify the range, but said employees of the range reached out to police after the shooting to report that Aghdam had practiced there.

"There seemed to be no kind of method or rhyme or reason to what she was doing". Law enforcement could have stopped the attack, had the officers done their jobs. It was not immediately clear why police later said the people shot were not specifically targeted.
