The frantic calls started pouring in at 1:24 p.m. A gunman was shooting people inside a sprawling manufacturing warehouse in Aurora, Ill.
Within four minutes, the first police officers rushed to the 29,000-square-foot building and were fired on immediately; one was struck outside and four others shot inside.
By the time the chaos ended Friday afternoon, five male employees of Henry Pratt Co. were dead and the gunman was killed in a shootout with police after a 90-minute search of the sprawling warehouse.
Five male police officers were hospitalized with injuries that were not life-threatening.
And the suburban Chicago city was left asking, “Why?”
“For so many years, we have seen similar situations throughout our nation and the horrible feeling that we get when we see it on the news. To experience it firsthand is even more painful,” said Aurora Mayor Richard C. Irvin.
Aurora Police Chief Kristen Ziman said the gunman, 45-year-old Gary Martin, was being fired from his job Friday after 15 years with the company.
“We don't know whether he had the gun on him at the time or if he went to retrieve it,” Ziman said.
She also said authorities didn’t know whether any of the victims were involved in his being fired. The names of those killed were not immediately released.
In addition to the five employees killed, a sixth worker was taken to a hospital with injuries that were not life-threatening.
A sixth police officer suffered a knee injury while officers were searching the building.
The shooting shocked the city of 200,000 people that is about 40 miles west of Chicago.
Christy Fonseca often worries about some of the gang-related crimes and shootings around her mother's Aurora neighborhood. But she never expected the type of phone call she got from her mom on Friday, warning her to be careful with a shooter loose in the town.
Police cars with screaming sirens revved past her as she drove to her mother's house, where the Henry Pratt building is visible from the porch stoop. It was only when they flipped on the television news that they realized Martin had killed people just a few hundred feet away.
“In Aurora, period, we'd never thought anything like this would happen,” Fonseca, a lifelong resident, said as she looked out at the warehouse where Henry Pratt employees make valves for industrial uses.
At Acorn Woods Condominiums, where Martin lived, neighbors gathered on sidewalks near the shooter’s condo talking and wondering among themselves whether they knew or had come in contact with him.
Mary McKnight stepped out of her car with a cherry cheesecake purchased for her son's birthday to find a flurry of police cars, officers and media trucks.
“This is a strange thing to come home to, right,” she said. She had just learned that the shooter lived close by and his unit in the complex had been taped off by police.
Asked whether Martin's rampage had been a “classic” workplace shooting, Ziman, the police chief, said: “I don't know. We can only surmise with a gentleman that's being terminated that this was something he intended to do.”
