AURORA, IL — Aurora police released the names of the five deceased victims in Friday's workplace shooting at a valve manufacturing plant on the city's west side, as well as updates on the condition of the six officers who were injured. Aurora Police Chief Kristen Ziman also expressed gratitude for the outpouring of love and support for the community and the police department.

"We feel the support from all of you, and my cup runneth over," Ziman said.

Johnson also expressed gratitude to the first responders and wounded police officers, and said help will be available for those affected by the tragedy:

"This tragedy has not just hit close to home – it has left all of Oswego grieving alongside our neighbors," she said. "Our thoughts are with the victims, and our condolences go out to our Oswego families, as well as to all the families who will be forever changed by yesterday's events. Know that our support is with you."

The shooting took place at Henry Pratt Company's manufacturing and warehouse building, located at 641 Archer Ave.

Police also gave an update on the five officers who suffered gunshot wounds, as well as a sixth officer who sustained a knee injury.

"All five are recovering and are under the care of physicians in the Chicago metro area," Ziman said, giving these details:

Shooter had history of violence

Ziman said the gunman, 45-year-old Gary Martin of the 1900 block of Selmarten Road in Aurora, should not have had a weapon after his FOID card was revoked in March 2014. The revocation was prompted after Martin applied for a concealed carry permit and submitted fingerprints, at which point authorities discovered he had a felony aggravated assault conviction for a 1995 stabbing in Mississippi.

Ziman said Martin, who worked for Henry Pratt for 15 years, had six prior arrests in Aurora, including incidents related to traffic violations and domestic violence. His last arrest in Aurora was in 2008 for violating an order of protection. His most recent arrest was in Oswego in 2017 for disorderly conduct and criminal damage to property, police said.

Asked whether the mass shooting had political implications, Ziman replied, "It's hard to bring politics into it, it's a violent act. The fact remains that some disgruntled person walked in with a firearm he shouldn't have had access to."

Ziman said Martin was reporting to work for a meeting at which he was fired. "My understanding from the witnesses is that he opened fire right at the termination meeting," she said. "We believe that several people who were involved in that meeting are the ones who are deceased."

Martin was armed with a .40 caliber Smith & Wesson handgun equipped with a laser, police said.

Ziman said Martin's felony conviction likely did not show up on his background check when he applied for a FOID card, but when the card was revoked he would have received a letter stating he needed to relinquish any firearms to police.

"Absolutely he was not supposed to be in possession of a firearm," Ziman said.
