that the search continues but it is believed one shooter. >> so your sources are telling you one shooter -- because there has been talk of two for quite some time. one shooter and the shooter is dead? >> it is believed only one shooter. i have to emphasize the base remains on lockdown. in the chaos they were getting conflicting reports about who was where, when? people were taken into hospital in private vehicles so it was unclear what the casualty count was. at one time it was as high as 14 or 15. now it is believed that eight wounded and four in grave condition at this hour and the search continues. it is believed, as you say, one possible shooter who is reportedly dead. >> and is the pentagon operating on the assumption that this is a member of the militaryt that did this? >> no clue. >> no clue at this point.
