It happened in a neighborhood off of 39th Avenue and Union Hills.
Police say they started getting 911 calls about a man on a motorcycle stabbing himself with a knife in the middle of the street.
When officers arrived, the man somehow threatened the officers with a knife.
At that point, at least two officers opened fire.
"We just heard like four or five shots, maybe six, ran to the door and he was down...there was three police officers on top of him with their guns pointed and that was it. It was all over," said a neighbor.
The man's name has not been released.
