DENVER -- Denver police are investigating a fatal shooting involving one of their officers.

Police responded to a home on the 3300 block of Navajo Street about 1 a.m. Tuesday on a report that there was a suicidal person armed with a knife.

When officers arrived at the scene, a 52-year-old man was in front of the house armed with a knife , Denver police said. Officers yelled at the man to drop the knife and there was a confrontation, witnesses said.

One officer fired and shot the suspect, who died at the scene.

An investigation determined that the initial call on a suicidal party came from the suspect himself, Denver police said.

The suspect had gone to a nearby home to call 911 and told the dispatch officer that either he or someone else was going to die.

A knife with a 10-inch blade was recovered from the scene.

Denver police are conducting a full investigation.

The name of the suspect and the two officers involved have not been released.
