>> okay. willie geist joins us. willie, jump in. >> pete, it's willie. as you say, these two suspects believed to have been here as long as a year. do we know in what capacity? were they students? do we know anything about why they've been here? >> presumably students. we don't have the answer to that. they're still trying to tentatively -- they're still waiting to get the positive identification. we don't know the precise nature of what the visa was or how they entered the u.s. >> as you say, a remarkable lockdown here. we're talking about the commuter rail, the t, the subway there, buses. that's people getting in and out of downtown boston. and the western suburbs essentially locked down. nobody allowed outside. newton, watertown, belmont, waltham, cambridge, alton, brighton. all in a state of lockdown. pete, do they have any leads at this point? a guy gets into a car and drives away. they said he fled on foot.
