New details tonight in the Washington Navy Yard shooting investigation.
We're hearing it's a horrific scene inside building 197. According to our Barbara Starr, officials say there is blood everywhere, and extensive damage including bullet holes, broken doors, and windows. It may be several weeks before the building re-opens.
And there are more stunning details tonight on how a local Navy base failed to report disturbing behavior by gunman Aaron Alexis, just weeks before he shot and killed 12 people.
