The brothers' escape from Boston to a Watertown backyard boat — and the message scrawled on its hull

The brothers' escape from Boston to a Watertown backyard boat — and the message scrawled on its hull

The boat sat in a backyard on Franklin Street in Watertown, covered and dry-docked for the winter.

Dzhokhar Tsarnaev was inside it when police found him on April 19, 2013.

He had written a message on the boat's interior.

Investigation records confirm the message existed.

They do not confirm its exact words.

The record does not establish what the message said, or what he meant by it.

That would require evidence.

The boat was discovered after a massive manhunt shut down the Boston area.

Streets emptied. Trains stopped. Soldiers stood at roadblocks.

Earlier that same day, Tamerlan Tsarnaev, the elder brother, had been killed in a shootout with police.

Dzhokhar escaped on foot.

He hid in the boat.

Investigators found him there, wounded and alive.

The message on the hull was documented.

Its meaning was not.

Some have called it a confession.

Some have called it a farewell.

Some have called it a boast.

The record supports none of those labels.

It supports only this: the words were there, written by a man who had been on the run for hours.

He was taken into custody.

The manhunt ended.

The boat stayed in the yard, its interior photographed and logged as evidence.

What he wrote remains part of the case file.

What he meant remains unknown.

BOYLSTON STREET, 2:49 P.M.

Patriot’s Day, 2013, and the finish line was full of spectators.

At 2:49 p.m., the first pressure-cooker bomb exploded on Boylston Street, according to the incident report.

Seconds later, a second bomb went off.

The medical examiner’s office identified the dead: Krystle Campbell, a 29-year-old restaurant manager; Lingzi Lu, a 23-year-old graduate student at Boston University; and Martin Richard, an 8-year-old boy.

More than 260 others were injured, many suffering amputations, the incident report stated.

The bombs had been placed in backpacks and left on the sidewalk among the crowd, according to investigation records.

The exact contents of those backpacks beyond the pressure-cooker bombs are not specified in the record.

Chaos unfolded immediately.

Emergency responders and medical personnel already at the scene treated the wounded.

Within hours, the FBI took over the investigation, according to public briefings led by special agent in charge Richard DesLauriers.

Three people were dead.

A city was in lockdown.
