There has been no apprehension in the search for Boston Marathon bombing suspect Dzhokhar Tsarnaev. However, police said in a press conference late Friday afternoon that authorities are still working on ballistics and forensics investigations, which are expected to be finished within the next few days.
Officers said they were pulling back tactical teams from Watertown, but adding deeper, saturated patrols in the area. The shelter-in-place advisory has been lifted and transit service is also being reinstated. Residents were encouraged to "remain vigilant" by Massachusetts Governor Deval Patrick.
Police believe Tsarnaev is still in Massachusetts.
Anyone with any information should call 1-800-CALL-FBI.
One of the two suspects in Monday's Boston Marathon bombing is dead and the other is on the loose in the midst of a massive manhunt throughout Boston.
The incident began with the fatal shooting of MIT campus police officer 26-year-old Sean Collier, who was responding to a disturbance near Vassar and Main streets just before 11:00 p.m. ET. The suspects are said to have shot the MIT officer in the head and taken his vehicle. According to police, the men then carjacked a Mercedes SUV. According to NBC, the driver of the SUV was held for about a half hour while the two men tried to use his cash card to get money from three ATMs. At the second ATM, $800 was taken out, but the two were told they exceeded the withdrawal limit at the third. The SUV's driver was released, unharmed, at a Cambridge gas station before a police chase ensued.
The two suspects allegedly threw explosives out of the window of the moving SUV and exchanged gunfire with police. Tamerlan Tsarnaev, 26, was hit and then taken into custody before dying at a local hospital. He is said to be the Boston Marathon bombing suspect seen wearing a black hat in photos released earlier Thursday by the FBI. According to NBC News, he had an improvised explosive device strapped to his chest. Doctors say he had a possibly blast injury and multiple gunshot wounds.
The other suspect, 19-year-old Dzhokhar A. Tsarnaev, the Boston Marathon suspect seen wearing a white hat in the released photos, drove the SUV past police, escaping, and is still on the loose. He is allegedly the one who placed the bags containing the bombs near the finish line of the marathon. He is considered armed and dangerous by authorities. Police described him as a "terrorist" who came to the country "to kill people." The two brothers moved to the United States from a region near Chechnya in 2002 or 2003. Both are legal U.S. citizens.
Mass transit in Boston has been shut down and residents in Watertown, Newton, Waltham, Belmont, Cambridge, and the Allston-Brighton neighborhoods were advised to stay indoors. Police, meanwhile, were going door-to-door looking for the Dzhokhar and a possible accomplice.
According to NBC News, authorities took two people into custody at 410 Norfolk Street in Watertown. The brothers are said to have shared the home with family. The two in custody (not under arrest) are not suspects.
Around 10:20 a.m. ET, Connecticut State Police recovered a gray Honda CRV believed to be linked to Dzhokhar in Boston. Police say he and his brother spent the night in the car and used it to carjack the Mercedes SUV. Police say after letting the carjacking victim go, one brother left in the SUV and the other left in the Honda. The driver of the Honda then ditched the car and reunited with his brother in the SUV. Both brothers were in the SUV when they encountered police and Tamerlan was killed in an exchange of gunfire.
Just fifteen minutes later, the University of Massachusetts Dartmouth closed and evacuated its campus after confirming Dzhokhar is registered at the school. The administration said the closure was done out of caution.
The FBI is at the New Jersey home of the Tsarnaev brothers. According to the West New York, New Jersey police director, the woman said she did not have frequent contact with the two men and is very upset. She did tell The Star-Ledger of Newark that the two are smart and great people and she doesn't know what got into them. She added that she was sorry for all those who were hurt.
