Colorado police said four people were killed and at least three others were injured, including an officer, in a shooting spree in two cities Monday night.

It ended when the suspect was shot and killed.

Police say it started in Denver, Colorado, and moved into Lakewood.

There was a shootout with police chasing the suspect's car, and he later escaped on foot.

Police said when officers caught up with him, he shot one of them.

The suspect continued to fire and was eventually shot and killed, but it's unclear if he was shot by an officer.

The officer who was shot is undergoing surgery.

No one involved has been identified.

There's no word on the motive behind the shooting spree.

This is breaking news and the story will be updated as more information becomes available.

An undisclosed amount of cash and checks were found in a wall at Joel Osteen's Lakewood Church in Houston, Texas.

The discovery was made public when the plumber, who found the money, spoke on a morning show at 100.3 The Bull.

“There was a loose toilet in the wall, and we removed the tile,” the plumber said, according to NBC affiliate KPRC. “We went to go remove the toilet, and I moved some insulation away, and about 500 envelopes fell out of the wall, and I was like ‘Oh wow!’”

The Houston Chronicle reports that the church confirmed the discovery.

"Lakewood immediately notified the Houston Police Department and is assisting them with their investigation," a church representative said in a statement.

The discovery comes seven years after the church reported that $600,000 in cash and checks were stolen from a safe.

According to the Houston Chronicle, no arrests were made in the case.

At this point, it's unclear whether the newly-discovered money is the same as the cash and checks that were stolen in 2014.
