ViralRead will be updating throughout the week with just the facts of the Boston Marathon tragedy. We will update what we have learned about the victims, the progress of the investigation and any new developments that we learn throughout the day.

New Developments Today

• The second suspect, 19-year-old Dzhokar Tsarnaev, has been captured after being found by a homeowner hiding in a covered boat in the homeowner’s backyard. The homeowner went outside, only after police and the FBI announced that citizens were cleared to go outside with caution. The homeowner noticed blood on the boat and called 911.
• Police surrounded the boat. There was a shootout between police and Tsarnaev. Flashbangs were used. A state police helicopter hovered above the property shining a spotlight on the boat and using infrared cameras to locate and confirm the suspect was in the covered boat and moving around.
• Last night, around 10:30 p.m. ET, Tsarnaev and his brother Tamerlan, allegedly ambushed 26-year-old MIT police officer Sean Collier, and killed him in his police cruiser, as Collier was responding to a disturbance call.
• The brothers then allegedly carjacked a vehicle at a convenience store in Cambridge and were pursued by police to Watertown, MA about 4 miles away. There was a major firefight, with over 200 rounds of ammunition fired. The brothers tossed two homemade hand grenades at police and set off two additional improvised explosives, similar to those used in the marathon attack.

Bomb Device

• Two bombs detonated very near the finish line of the Boston Marathon. The first bomb, the closest to the finish line exploded in a spectators area at the 4:09:44 mark in the race. The second bomb detonated about 100 yards up the block, away from the finish line, 12 seconds after the first detonation.
• The bombs have been described as “crude” and “low explosives”
• The bombs were made partially out of pressure cookers and were filled with “anti-personnel” packing. They were filled with ball bearings, BBs, nails and other metal pieces.
• The bombs were concealed in either duffel bags or backpacks and left on the ground or possibly in trash cans.
• Law enforcement said that at least one of the bombs used a timing device and not a remote detonator.

Investigation

• The FBI released photos and video of the men they consider suspects in the bombings. The men were dressed in jackets and carried backpacks. One wore a white cap backward, one wore a black cap. The FBI says they have seen video footage of one of the men placing the bag on the ground and waling away.
• A 17-year-old high school student, Salah Barhoun, was shocked to see his picture on the cover of the NY Post. He and his track coach had attended the marathon and the two were misidentified by multiple media outlets as suspects.
• FBI has stated that they have not made an arrest and issued a stern rebuke to media outlets who had reported that a suspect was in custody.
• Law enforcement does not have any suspect in custody, according to Boston police commissioner Ed Davis.
• Officials from Saudi Arabia and the US have confirmed that more than one Saudi national has been questioned, but are not suspects at this time. CNN is reporting that one is a male, and his apartment was searched late Monday night, and the other is a female.
• One Saudi national was questioned in the hospital as a witness. He was injured by one of the bombs.
• That individual’s home was searched by the FBI and three bags were removed from the home. The man’s roommate, also a Saudi national in country on a student visa, said that police told him his roommate was injured by the bomb and was in the hospital. He also said he didn’t believe either of his two roommates would be involved in the bombings because they are “good people.”
• Investigators have said they are looking for a “person of interest” who has dark skin, speaks with a foreign accent, was wearing a dark sweatshirt and carried a black backpack. The person was allegedly trying to enter a restricted area minutes before the bombs exploded.
• Two explosive ordnance disposal sweeps were carried out Monday, the first early in the morning and the second an hour before the first runners crossed the finish line and did not turn up any evidence.
