Two Waterloo Police Department officers were shot Sunday morning, and police shot and killed the man involved, according to a police department news release.

Police had responded to a report of a man with a gun in the 200 block of Manson Street at about 8:22 a.m., police said. The shootings happened in the 1200 block of East Fourth Street. It’s unclear how the shootings unfolded, but the release said the man was declared dead at the scene.

The two police officers were transported to a local hospital, the release said. The officers were undergoing surgery but were expected to survive, the Waterloo Courier reported.

The Iowa Division of Criminal Investigation is conducting an investigation, a standard procedure for officer-involved shootings.

The Courier reported that the suspect’s mother came to the scene and talked with police and Mayor Quentin Hart.

“I just wanted to stay down here long enough until they picked my baby’s body off the ground, and I did that,” the mother told the Courier. “They said he was running through the park, and the police Tased him, and they say my son ended up shooting two of the police officers after he was down on the ground.”

The Des Moines Police Department posted a message in support of the Waterloo officers and the department with a headline image that reads, “We Stand With You.” The message also says, “The men and women of the DMPD offer their support to and stand with the fellow officers, family, & friends of the Waterloo Police Department police officers shot in the line of duty today.

“Prayers for a swift recovery.”
