What exactly happened in Olde Town Arvada Monday? We know three people are dead. An officer. A man police describe as "a good Samaritan." And the alleged attacker. What is less clear is who shot whom. Notably: who killed the civilian police say was trying to help? We're also curious how Old Towne moves forward. It's a neighborhood that was just seeing a light at the end of the pandemic tunnel. We are joined by Arvada's mayor, Marc Williams.
