Updated 10:18 a.m. ET
WASHINGTON Federal official say as many as 10 people have been shot at the Washington Navy Yard on Monday morning. D.C. Metropolitan Police said earlier at least 3 civilians, one D.C. officer and one base security officer were among the victims.
An official told CBS News the number of victims could be higher because it is a "chaotic scene." Officials have not offered publicly an exact assessment of the health of the victims.
Officials tell CBS News correspondent Bob Orr a gunman has been neutralized, and that security officials are searching for a potential second gunman, although there is no confirmation or corroboration of a second gunman. It is not clear whether neutralized gunman is a member of the Navy.
7:42 AM PT: reports are now coming from cbs that 4 are dead and 10 wounded. the report that the shooter has been "neutralized" is not confirmed.,
7:55 AM PT: scanner states "there is a second suspect possibly in scene ... is not secure." so this looks like those searching the scene are taking no chances that a second shooter might be at large.
8:05 AM PT: swat team still surrounding base and police helicopters have heavy presence.
abc is reporting that 10-12 shot and MAYBE four dead - no confirmation. copters shown loading living injured at scene.
DOT is on lockdown (thanks, wmtriallawyer).
the report of more than one government has not been confirmed - but the police are acting as if there were.
this is an annex for the navy - on the river.
among the wounded are members of law enforcement who responded. the shooter had at least one rifle and one hand gun and maybe more weapons.
there are reports of what sounds like gunshots in other buildings - so that is why the scene is not secure.
the gunman has been "contained" so he can't move around further - not "neutralized" in the james bond sense.
10:22 AM PT: here is the latest (since i woke up) - the lone gunman has been killed, according to cbs news. also as many as 10 shot and six have died.
this appears to be a disgruntled employee with a history of alcohol problems.
he was not in fatigues (as reported earlier) but was in dark blue clothing.
At least 12 people are dead after a shooting Monday morning in a heavily secured building at the D.C. Navy Yard, and authorities now say they have identified the gunman.
That gunman, 34-year-old Aaron Alexis of Fort Worth, Texas, is among the 12 dead. Officials said he recently began working as a civilian contractor.
The FBI, which now is leading the investigation, believes the gunman used the identification of a man who used to work at Navy Yard, reported Pete Williams of NBC News. The ID was found next to the gunman's body in Building 197, where most of the victims were shot on the third and fourth floors.
