According to Colorado Springs Police Department spokesman Lt. Pamela Castro, the first report of a shooting at the nightclub came in at 11:56 p.m.
She claimed that within six minutes, police had barged into Club Q and arrested a suspect after discovering him to be hurt and receiving medical attention elsewhere.
Adrian Vasquez, the city's police chief, revealed at a press conference that the shooter had a long rifle. The chief reported that two guns were found at the club.
He named the suspect as 22-year-old Anderson Lee Aldrich and added that authorities were looking into his motivation.
According to Lieutenant Castro, the injured were transported to a number of hospitals; however, the precise number of injured is questionable because
some of them also drove themselves to receive care. According to officials, not all of the injuries were caused by gunshots.
Several Colorado lawmakers denounced the shooting, and the F.B.I. claimed to be involved in the investigation.
Gov. Jared Polis praised the "brave people" who "blocked the gunman" at the club in a statement.
