On February 15, 2019, a mass shooting took place at the Henry Pratt Company in Aurora, Illinois, United States.

Six people died, including the perpetrator, 45-year-old former employee Gary Montez Martin, who was shot and killed by responding police officers.

[11] The five victims fatally shot were male workers at the Henry Pratt plant: a 32-year-old human resources manager, a 37-year-old plant manager,[12] a 46-year-old mold operator, a 55-year-old stock room attendant and forklift operator, and a 21-year-old student of Northern Illinois University on his first day as a human resources intern.

[6][13] A sixth plant employee sustained gunshot wounds during the shooting and was hospitalized with non-life-threatening injuries.

[4] Relatives of the shooter told reporters that he had been released from his position at the company about two weeks prior to the shooting.

The Illinois State Police rejected his concealed carry application, cancelled his FOID card and sent him a written notice demanding that he turn in the gun that he had purchased.

[18] According to a CNN report, the authorities are now trying "to determine why he didn't surrender the weapon and whether law enforcement followed up with him to confiscate the gun.

[23] Aurora Mayor Richard Irvin said, "It's a shame that mass shootings such as this have become commonplace in our country [and] that a cold and heartless offender would be so selfish as to think he has the right to take an innocent life.
