-- The University of Massachusetts-Dartmouth, where Dzhokar Tsarnaev was enrolled, is evacuated. Law enforcement personnel swarm the campus, which is just west of New Bedford and about 60 miles south of Boston.
-- Numerous activities scheduled for Friday night are canceled around Boston -- including Boston Red Sox and Boston Bruins games, as well as a Big Apple Circus show -- because of the ongoing manhunt for the marathon bombing suspect.
-- Amtrak train and Greyhound and regional Bolt Bus services are shut down. Taxi service across the city also was suspended for a time during the manhunt.
-- Around 6 p.m., Gov. Deval Patrick says that the lockdown has been lifted and that mass transit service has resumed.
-- After officials announce the "shelter-in-place" order has been lifted and people can go back outside, a Watertown resident takes a walk.
-- A man sees blood on a boat in a backyard, then "saw a man covered with blood under a tarp," Boston Police Commissioner Ed Davis said.
-- The resident then calls police. Helicopters later confirm there was a man believed to be the suspect in the boat, as law enforcement officers converged on the scene.
-- Law enforcement officials make a number of appeals to the person apparently inside the boat: "Come out on your own terms"; "We know you're in there" and "Come out with your hands up."
-- At some point, gunfire is exchanged between law enforcement personnel and the suspect in the boat. Authorities also use flash bangs to try to stun Dzhokar Tsarnaev.
-- Police in Watertown break out in cheers, shouting "Yay!" A crowd of neighbors also cheers. Police begin heading away from the backyard of a Watertown home where they say the suspect, Dzhokar Tsarnaev, was holed up in a boat. Someone asks a law enforcement officer, who responds, "Yes."
-- Boston police tweet the "suspect is in custody." Twelve minutes later, they put out another post: "CAPTURED!!! The hunt is over. The search is done. The terror is over. And justice has won. Suspect in custody."
-- Government and law enforcement officials hold a news conference marking a milestone in what FBI Special Agent in Charge Richard DesLauriers called "truly an absolutely intense investigation."
-- "We're so grateful to bring justice and closure to this case," Massachusetts State Police spokesman Col. Timothy Alben said.
-- People spill into the streets to celebrate Dzhokar Tsarnaev's capture and thank law enforcement personnel who hunted him down. In Watertown, they line the streets as police head from the scene, yelling, "Thank you!" and "You guys are awesome." Similar spontaneous demonstrations of support break out in Boston, with college students and others chanting "BPD!" -- for the Boston Police Department -- and "USA."
Says 21-year-old Zara Pokrandt, "It's just a massive relief."
