Anderson Cooper reports on the investigation into Michael Brown's death, and the violence that led Missouri's Governor to call in the National Guard.

More than 22,000 residents call Ferguson, Missouri their home. After several nights of protests and violence, the Saint Louis suburb looked more like a war zone. This is raising troubling questions about the future for some local businesses. Ana Cabrera takes a closer look.

The release of surveillance video that shows an alleged robbery involving Michael Brown just before the shooting has enflamed tensions in Ferguson. Now serious questions are being asked about the decision to make that video public while keeping other parts of the investigation private. Anderson pressed for answers when he spoke with Detective Gabe Crocker, who is the President of the Saint Louis County Police Association.

The preliminary results of a private autopsy reveal that Michael Brown was shot at least six times. Shawn Parcells is a medical investigator who assisted on that autopsy. He says the last two bullets fired at Michael Brown struck his head. Anderson spoke with Parcells about the key pieces of evidence that are still needed to put together a complete picture of what happened in Brown's final moments.

We are getting a new description of the shooting of Michael Brown from a woman calling herself "Josie" and claiming to be a friend of the police officer who fired the fatal shots. She describes Brown pushing officer Darren Wilson and punching him in the face. That contradicts the account given by Michael Brown's friend Dorian Johnson, who was with him at the time and witnessed the shooting. Attorney Benjamin Crump is representing the Brown family. He spoke to Anderson and described the shooting as an execution.
