One of those explosives was a pressure cooker bomb similar to the ones used in the marathon bombs; Deveaux said its remains were found embedded in a car down the street. Two devices that didn’t explode were also found, he said.
“How the Watertown police aren’t attending a funeral of our own based on what happened on that street over that period of time is just talent, guts and glory that my officers did,” Deveaux said.
He said the gunfight was largely over by the time “the whole greater Boston area” was arriving to help, though one of the earliest to arrive, a Metropolitan Boston Transit Authority officer, was seriously wounded.
Deveaux offered an almost cinematic description of Tamerlan Tsarnaev’s final moments. He said the 26-year-old amateur boxer had begun walking down the street, firing at the Watertown police, when he ran out of ammunition. A Watertown officer tackled him, and police began to handcuff him.
But Deveaux said his officers suddenly saw the carjacked car aimed at them and dived out of the way. That’s when the younger Tsarnaev ran over his brother and dragged him “a short distance down the street.”
With Dzhokhar Tsarnaev under arrest – he remained in serious condition Saturday – investigators were still left to piece together the events that had left four people dead in five days of carnage – three killed by the two bombs that exploded along the marathon’s route on Monday and MIT officer Sean Collier, shot dead Thursday night.
Fifty-three people injured in Monday’s bombing were still in the hospital, three in serious condition, and the MBTA officer wounded in the shootout remained hospitalized.
Deveaux said his department has three cruisers “that will never drive again that are shot up. There’s a lot of damage.”
And as investigators piece together what prompted the brothers to target the marathon, they are also looking at how they got the weapons, Deveaux said.
“We have to figure that out,” he said. “We have to find out more about this. And we will as the days go on.”
On Franklin Street, too, they sought answers. Joy Arcolano missed the marathon for one of the first times in a decade on Monday because she and her husband wanted to seed the front lawn at their Franklin Street home. On Friday, they huddled at home as helicopters hovered and police exchanged gun fire with a fugitive.
“There’s all these things you’re supposed to do in a suburb,” she said, standing on her porch Saturday morning. “Not crouching down in a spare bedroom waiting for the gun fire to be over.”
But Arcolano said they’ll be back at next year’s race – held every year on a state holiday known as Patriots Day.
“We’re determined to keep it as the awesome special day it is,” she said.
