We're on the scene with the very latest developments on the Boston bombing aftermath and hunt. Top experts and reporters join us.

Dramatic developments in Boston today as a huge manhunt comes down on the suspects in Monday’s Boston Marathon bombing.

In a matter of hours, we went from images being shared with the public of two young suspects on the street before the attacks, to heavy gunfire, chase, security sweeps and lockdown in the streets around Boston.

One suspect, dead.  Dead and wounded police.  Carjacking and explosives reported.  A Chechen connection.  And a very fluid, dangerous situation.

Up next On Point:  Manhunt, and what we have learned.
