The Colorado Springs Mayor praised "two heroes" who helped pin down the gunman.
A Colorado man was facing murder and potential hate crime charges on Monday after a shooting rampage at an LGBTQ nightclub, as a US Army veteran recounted how he "went into combat mode" to quickly subdue the gunman.
Anderson Lee Aldrich, 22, was arrested following the Saturday night shooting at Club Q in Colorado Springs that left five people dead and at least 18 injured, officials said.
Currently held without bond in hospital after being overpowered by club patrons, the alleged gunman will make a first court appearance in the next few days, El Paso County District Attorney Michael Allen said.
Formal charges have not yet been filed but Aldrich is expected to face first-degree murder charges and "if the evidence supports bias-motivated crimes, we will charge that as well," Allen said.
Colorado Springs Mayor John Suthers praised "two heroes" who helped pin down the gunman after he entered the club and opened fire.
"I think in the opinion of everyone involved, (they) saved a lot of lives," Suthers said.
The mayor said he had spoken to one of the men -- Richard Fierro, a 15-year veteran of the US Army, according to The New York Times.
"I have never encountered a person who had engaged in such heroic actions that was so humble about it," Suthers said. "He simply said to me, 'I was trying to protect my family.'"
In an interview with the Times, Fierro said he was at the club with his wife, daughter and friends watching a drag show when the gunfire began.
The 45-year-old Fierro, who was deployed to Iraq and Afghanistan during his military service, said he tackled the gunman by grabbing a handle on the back of his body armor, took his pistol and beat him with it.
"I don't know exactly what I did, I just went into combat mode," he said. "I just know I have to kill this guy before he kills us.
"I grabbed the gun out of his hand and just started hitting him in the head, over and over," he told the newspaper.
The attack was the deadliest on the LGBTQ community in the United States since a 2016 mass shooting at a nightclub in Orlando, Florida that claimed 49 lives.
GLAAD, an LGBTQ advocacy organization, noted that it came on the eve of the Transgender Day of Remembrance, which honors victims of transphobic attacks, and amid an uptick in hostility against the LGBTQ community in the United States.
"You can draw a straight line from the false and vile rhetoric about LGBTQ people spread by extremists and amplified across social media, to the nearly 300 anti-LGBTQ bills introduced this year, to the dozens of attacks on our community like this one," GLAAD president Sarah Kate Ellis said in a statement.
Colorado Representative Brianna Titone, an openly transgender state legislator, also singled out anti-LGBTQ rhetoric.
"When politicians and pundits keep perpetuating tropes, insults, and misinformation about the trans and LGBTQ+ community, this is a result," Titone tweeted.
Transgender rights were a hot-button issue in the United States leading up to midterm elections earlier this month, with Republicans putting forward a slew of legislative proposals to restrict them.
Adrian Vasquez, the Colorado Springs police chief, said the shooting suspect was armed with an "AR-style" rifle and a handgun.
Vasquez condemned what he called an "evil act" and pledged to do everything he can to make the community feel safe again.
Gun violence is alarmingly common in the United States. This year there have been more than 600 mass shootings across the country, according to the Gun Violence Archive, which defines such incidents as shootings of four or more people, not including any gunman.
'We'll keep going'
On Monday evening, hundreds of people gathered in a Colorado Springs park for an emotional candlelit vigil paying respect to those who were murdered.
Speakers praised the resilience of the LGBTQ community in the Rocky Mountain city, and insisted it would not be cowed by the horrific violence of Saturday night.
"I'm so glad that everybody was able to come together," 25-year-old body piercer Bunnie Phantom told AFP.
"To see everybody here, to have the support and representation in the community... literally means the world to me."
Allie Porter, who paid a tearful tribute from the stage to those killed, said she had felt the warm embrace of the local community for the 30 years she had lived in the city.
She vowed it would not be changed by the horrors of the weekend.
"We'll keep going the same way as we always have. We've dealt with this for years, decades, and we've consistently rebuilt," she said.
