Witnesses said a bystander in the right place at the right time jumped in to stop a gunman who shot two people near Pike Place Market in downtown Seattle.

The shooting suspect was just 16, and KOMO News has learned that he teamed up with several accomplices to confront a group of young people around 10 p.m. Wednesday at First Avenue and Union Street, in the heart of the city’s tourism district.

As the gunfire began, a man with his own firearm stepped out of the shadows and killed the teenage shooter. The medical examiner has since identified the deceased as Kale Vaughn Kellen Nusbaum. All three people were shot in front of the Four Seasons hotel, and many of the rounds struck a condominium building across the street.
