contractor killing 12 people. so many people injured in that incident. we don't know what the scenario is here. this seems to be a situation that is developing rapidly. obviously you recall that day with horror i'm sure because you were there on the ground seeing the aftermath of all that. this is very close to that same building, do we know? >> reporter: we don't have specifics on exactly where on the grounds this may have happened. the only information that we have is that there is a report of an active shooter at the navy yard. it is in that general vicinity. and you know going back to 2013, i remember speaking to someone who actually witnessed the shooting and he explained such graphic details. so i know in speaking to many of those people that it was quite traumatic. you know, you show up for work one day not expecting this sort of situation only to see something like that unfold before your very eyes.
