WATERTOWN, Mass. — The Massachusetts State Police gave the public a new perspective of the Watertown manhunt when it released photos of the boat where the second marathon bombing suspect was found.
The images were shot by the State Police Air Wing and show the heat signature of a person lying down.
They were tipped off when a Watertown man, cooped up in his house all day because of a “shelter in place” order, finally stepped outside when the order was lifted.
David Henneberry soon noticed the tarp covering the boat in his backyard was flapping in the wind and a retention strap was cut. He also noticed a small amount of blood on the tarp.
“He basically stuck his head under the tarp, noticed a pool of blood,” Henneberry’s stepson Robert Duffy told CNN.
Henneberry discovered a man curled up in a ball.
“And at that point he became an absolute hero. Instead of being a hero at the moment and yelling at what we now know was the suspect, he did the right thing as law enforcement had urged” and called 911, Duffy said.
Authorities arrived and evacuated Duffy’s stepfather. Using a bullhorn, they called out to the suspect: “Come out with your hands up.”
The bloodied man refused.
“We used a robot to pull the tarp off the boat,” David Procopio of the Massachusetts State Police said. “We were also watching him with a thermal imaging camera in our helicopter. He was weakened by blood loss — injured last night, most likely.”
A gunfight ensued, with more than 20 rounds fired.
Authorities eventually rushed the boat and took Dzhokar Tsarnaev into custody.
