Five people were killed and at least 19 others were injured during a mass shooting Saturday at an LGBTQ nightclub in Colorado Springs, Colorado.

A 22-year-old shooter entered Club Q just before midnight Saturday and immediately opened fire, authorities said. Police praised "at least two heroic people" inside who confronted the shooter and stopped the attack.

Authorities say the suspected shooter, identified as Anderson Lee Aldrich, received medical treatment and is now in the custody of the El Paso County Sheriff's Office. Aldrich is facing five counts of first-degree murder and five counts of a bias-motivated crime causing bodily injury, according to an online docket in the El Paso County Court.

The location of the shooting is reminiscent of the 2016 attack at an LGBTQ nightclub in Orlando, when a shooter who pledged allegiance to the Islamic State killed 49 people. Colorado has been the site of some of the most heinous mass shootings in US history, including the 1999 shooting in Columbine High School and the 2012 movie theater shooting in Aurora.
