Two officers with the Denver Police Department who fatally shot a man who lunged at them with an edged weapon early this year have been cleared of any wrongdoing.

According to the Denver Post, District attorney Beth McCann ruled on Monday that the officers' actions were justified because the subject—identified as 27-year-old Gerardo Antonio Conchas-Bustos—had already attacked people in his home and posed a threat to the officers' safety as well as the safety of others present at the scene.

As the two officers walked through the home with their guns drawn, Conchas-Bustos came quickly up a set of basement stairs and moved toward officers with a large knife in his hand.

The officers opened fire, striking the assailant several times. They attempted to then perform life-saving medical aid, but Conchas-Bustos died from his wounds.
