The manhunt for the 19-year-old suspect in the Boston Marathon bombings is not over. But we now know more about the saga that's unfolded in the past 24 hours, including the tragic death of MIT police officer Sean Collier.
Dzhokar Tsarnaev and his brother Tamerlan Tsarnaev were identified by police as the suspects in the photos released by the FBI on Thursday at an evening press conference. Hours later the men engaged in a gun battle with law enforcement and threw explosives. Dzhokar got away, driving over his brother who was shot by police. Tamerlan later died at a Boston hospital.
A source tells CNN that he was wearing explosives and a triggering device. Anderson will interview the doctor who treated the suspect and also cared for the victims of the attack this week.
After Dzhokar's escape in Watertown, parts of Boston were on lockdown, transit ceased, and residents were instructed to only open their doors for police. Heavily armed officers launched a door-to-door search. The stay indoors request had been lifted this evening, but that statement was retracted around 7 p.m. when gunshots were heard in the Watertown area and police swarmed the scene.
Anderson reports from Boston on the latest, and he'll speak with friends and others who knew the suspects and their family. Tune in at 8 and 10 p.m. ET.
