One of the most intense and frightening manhunts in our nation's history ended Friday night, in a hail of flash bangs, bullets, and laser scopes in Watertown, Massachusetts, when police finally tracked down terror suspect Dzhokhar Tsarnaev in a docked boat parked in someone's backyard.
Late Saturday afternoon, police released brand new thermal images showing the body outline of the suspect, cowering inside the boat.
The final moments of the capture came through a deft combination of tenacity and technology. Police had spent the day cutting off all avenues of escape from suburban Watertown. When the call came from a homeowner who saw the torn tarp on his boat, blood stains, and a person crouching inside, hundreds of officers raced to the scene.
As they hustled folks in the neighborhood away to safety, a helicopter with a sensor to detect heat sources flew over the boat and ascertained that there was someone inside, and he was moving.
In fairly short order, a gunfight broke out between the subject in the boat and police, during which authorities suggest he was hit at least two more times, they threw in flash-bang grenades to try and stun him.
The next thing police did was bring in a robotic armed vehicle that could reach into the boat and tear away some of the fabric, giving police a better view.
Finally, police brought in thermal imaging again, and saw the suspect collapsed in the boat, unable - as authorities would say later - to offer any more resistance. Police made him stand up at the edge of the boat, raise his clothing to show he had no weapons or explosions on him, and then finally make the arrest.
