Authorities said five people are dead after an employee opened fire at a manufacturing plant in Aurora, Illinois, on Friday afternoon.  Multiple people were hurt during the incident; five police officers were shot and one suffered a knee injury.

On Friday night, police confirmed the officers are in stable condition.

The suspected gunman was also killed.  The Aurora Police Department identified the suspected gunman as 45-year-old Gary Martin.

The department believes he was an employee at Henry Pratt Company, where the shooting happened.

Police said the gunman's motive is unclear.

Schools in the area were under a soft lockdown while police were on the scene.

The Aurora Police Department tweeted the situation has been secured and that the "shooter is no longer a threat to the area." At a news conference, the city's mayor addressed the incident saying "today is a sad day in the city of Aurora." "It's a shame mass shootings, such as this, have become commonplace in our country," Mayor Richard Irvin said.

"It's shame that a cold and heartless offender would be so selfish as to think he has the right to take an innocent life."  After hearing the news, President Donald Trump tweeted his condolences to the victims and their families.  Former Rep.

Gabby Giffords survived the Tucson shooting back in 2011.

She criticized the president  on Twitter  and said: "It makes me sick to think that our country has a president who still refuses to acknowledge a real crisis when he sees one.

Americans should be able to go to work without fear of being shot.

This must stop."  The Aurora Police Department plans to provide additional updates regarding its investigation late Friday night.
