Dzhokhar Tsarnaev Manhunt LIVE Stream: Surviving Marathon Bomber is Being Hunted

Police sources have named the Boston Marathon suspects as Chechen brothers Dzhoktar and Tamerlan Tsarnaev. Tamerlan was killed in a Watertown firefight with police officers early Friday morning, but Dzhoktar is still at large and is believed to be heavily armed with firearms and explosives and extremely dangerous.

A full-Boston lockdown has been ordered. All Boston residents are told to stay inside until the threat has been resolved, underscoring the ongoing seriousness of the situation and the level of destruction officers believe the surviving terrorist is capable of.

For those wanting updates on the case and manhunt, 7 News Live has been reporting on the ongoing crisis since it began late Thursday night and has been doing a fantastic job of largely refraining from overspeculation or hyperbole.
