Boston: Police captured the surviving suspect in the Boston Marathon bombings in Watertown, Massachusetts, on Friday night, police and government officials said. Following a tense 24 hours for the Boston area, the manhunt ended with the 19-year-old suspect, Dzhokhar Tsarnaev, cornered, captured and taken into custody.
Here is a timeline of events:
Thursday, April 18, about 5:10 pm
- The FBI releases photographs and video of two men suspected of planting the pressure cooker bombs that killed three people and injured 176 at the Boston Marathon on Monday. Video footage shows a man known as suspect No. 1 wearing a dark baseball cap. He was later identified as Tamerlan Tsarnaev, 26.
Suspect No. 2, later identified as Tsarnaev's brother, Dzhokhar, 19, was wearing a white cap backwards in the images. The 30-second videos are played repeatedly on national television, and photographs of the suspects are posted online.
Thursday night at 9:04 pm
- Russian-language social networking site VK shows someone last logged out of what appears to be Dzhokhar Tsarnaev's page. The site had been accessed via mobile device.
Thursday night around 10:20 pm
