• A lone gunman killed four people in a shooting spree in the Denver area on Monday, reports said.
• The rampage ended with police officers killing the suspect, according to reports.

A lone gunman on Monday shot dead four people in the Denver area, in a rampage that ended with police officers killing the suspect, Reuters and other media reported, citing law enforcement statements.

Per Reuters, Denver Police Chief Paul Pazen said the shooting spree began around 5pm Monday when the suspect fatally shot two women and injured a man near downtown Denver.

The suspect then fled in a car to east Denver where he fatally shot another man, Pazen said. He later opened fire in a west Denver neighborhood, exchanged fire with police officers and disabled a police cruiser, but did not injure or kill anyone, Pazen said.

The suspect subsequently drove to Lakewood, a nearby city, where police officers tried to apprehend him, Lakewood Police spokesman John Romero told news outlets including Reuters.

He then exchanged fire with police officers and entered a hotel where he injured a clerk, then exchanged more fire with police officers when he was fatally wounded.

The suspect has not been named and police said they had not identified a motive.

"We believe that this individual was responsible for this very violent series of events that took place in the Denver metro area," Pazen told reporters in a press conference, per ABC News.

Pazen added: "This is the holiday season. To have this type of spree take place is not normal for our community."

He continued: "We cannot lose sight of the victims in this, the people who are still fighting for their lives, including a Lakewood agent."

Three people, including a police officer, were also injured in the attack, Reuters reported.

This is a developing story.
