New questions about the evidence presented to the Ferguson grand jury that decided not to indict Officer Darren Wilson in the death of Michael Brown. Saint Louis County Prosecutor Robert McCulloch has released more grand jury documents. He said they were left out by mistake when thousands of other documents were made public last month. CNN has been poring over the newly released information. The documents show the grand jury didn't just face an onslaught of witnesses with conflicting memories of what happened the day white police officer Darren Wilson killed Brown, an unarmed black teenager. It also heard from witnesses who had little to zero credibility. Ana Cabrera has more.
