(NECN: Josh Brogadir) - A major component of the Watertown, Mass. crime scene wrapped up around 5:30 p.m. Friday when authorities removed the boat the surviving Boston Marathon bombing suspect had hidden in from the backyard.
The 22-foot power boat in the backyard - a concluding chapter of the manhunt on Franklin Street in Watertown - is no longer there.
State police towed it out of the driveway and made their way out of Watertown and east on the Massachusetts Turnpike to an undisclosed location.
David Henneberry’s boat became the center of the continuing investigation into the marathon bombings, which left three dead and 264 wounded. Suspect Tamerlan Tsarnaev was killed in a shootout with police, and his younger brother Dzhokhar brought to justice from that boat.
The 19 year old was taken from the boat to Beth Israel Deaconess Medical Center for a week, then, under cover of darkness early Friday morning, was moved to Federal Medical Center Devens, housed with about 1,000 other inmates at the former Fort Devens Army base.
We have known that Russia had concerns about his older brother Tamerlan and contacted the CIA in 2011. But new information has been revealed about Zubeidat Tsarnaeva, the mother of the marathon bombing suspects, who was also added to a federal terrorism database, called TIDE, about 18 months before the marathon bombings.
She and Tamerlan were considered religious militants about to travel to Russia.
Tsarnaeva was arrested at the Natick Mall for shoplifting last year before she returned to her home country.
We’ve learned from NBC that her husband, Anzor Tsarnaev, was expected to come to the U.S. from Dagestan, in southern Russia Friday. But NBC News has learned he is sick and has delayed his trip.
Meantime, another site of interest for the FBI this week has been a landfill near the campus of UMass Dartmouth.
Dzhokhar had been studying mechanical engineering there, and NBC news has learned they are looking for receipts from fireworks purchases and a missing laptop.
Many questions have been raised about when the FBI and state police knew who the suspects were and when they disclosed that information.
Massachusetts State Police Col. Timothy Alben bristled about the notion that there was a delay, saying that they shared the information when they had it.
