An employee of a manufacturing company opened fire at its suburban Chicago plant Friday, killing five people and wounding five police officers before he was fatally shot, police said.

Aurora, Ill., police Chief Kristen Ziman identified the gunman as 45-year-old Gary Martin and said he was believed to be an employee at the Henry Pratt Co. โ€“ which makes valves for industrial purposes โ€“ in the city about 40 miles west of Chicago. She told a news conference that officers arrived within four minutes of receiving reports of the shooting and were fired upon as soon as they entered the 29,000-square-foot manufacturing warehouse.

Police said they did not know the gunmanโ€™s motive.

โ€œMay God bless the brave law enforcement officers who continue to run toward danger,โ€ Illinois Gov. J.B. Pritzker said at the news conference.

Hospitals reported treating at least seven patients from the shooting, though their conditions werenโ€™t released. Two of the officers were airlifted to trauma centers in Chicago, Ziman said. She said a sixth officer suffered a knee injury. Officials did not say the total number of people injured including police and civilians.

Dozens of first responder vehicles converged on the building housing the company in Aurora after police received multiple calls about an active shooter at 1:24 p.m. CST.

Several ATF teams also responded to the shooting and were at the scene, according to the agencyโ€™s Chicago spokeswoman, and the FBI said it also responded.

John Probst, an employee at the Henry Pratt Co. in Aurora, told ABC7 that he ran out of the back door as the shooting unfolded Friday afternoon. Probst says he recognized the gunman and that he works for the company.

โ€œWhat I saw was the guy running down the aisle with a pistol with a laser on it,โ€ Probst said.

Probst said he wasnโ€™t hurt but that another colleague was โ€œbleeding pretty bad.โ€

โ€œItโ€™s a shame that mass shootings such as this have become commonplace in our country. Itโ€™s a shame that a cold and heartless offender would be so selfish as to think he has the right to take an innocent life,โ€ Aurora Mayor Richard C. Irvin said.

At Acorn Woods Condominiums where Martin lived, a mix of brick apartments and condos nestled on a quiet street just a mile and a half from the shooting, neighbors gathered on sidewalks near Martinโ€™s unit talking and wondering among themselves if they knew or had come in contact with him.

Mary McKnight stepped out of her car with a cherry cheesecake purchased for her sonโ€™s birthday, to find a flurry of police cars, officers and media trucks.

โ€œThis is a strange thing to come home to, right?โ€ she said. She had just learned that the shooter lived close by and his unit in the complex had been taped off by police.

The White House said President Donald Trump was briefed on the shooting and monitoring the situation as he prepared to depart for a weekend trip to his home in Palm Beach, Fla. Trump tweeted his thanks to law enforcement officers in Aurora and offered his condolences to the victims and their families. โ€œAmerica is with you,โ€ the tweet said.

Presence Mercy Medical Center was treating two patients and a third had been transferred by helicopter to another hospital, spokesman Matt Wakely said. Advocate Good Samaritan Hospital and Advocate Lutheran General Hospital each had one patient from the shooting, spokeswoman Kate Eller said. Rush Copley Medical Center received three patients from the shooting and all are being treated for non-life threatening injuries, spokeswoman Courtney Satlak said.
