2:49pm
Dzhokhar Tsarnaev lifts the phone to his head and speaks for about 18 seconds. He finishes the call, and the first explosion goes off within seconds. A few seconds later, his brother starts moving west--away from the finish line, and not carrying the knapsack he'd once had. About 10 seconds later, there's an explosion where Dzhokhar Tsarnaev had put the bag--about a block from the first blast.

11pm

Massachusetts Institute of Technology police officer Sean Collier, 26, is shot dead on the school's Cambridge, Massachusetts, campus -- a killing authorities later link to the Tsarnaevs.

April 19, 2013

Early morning
Police say the two suspects hijack a car at gunpoint in Cambridge, Massachusetts, taking the driver as a hostage. One suspect tells the driver they are the Boston Marathon bombers, and the suspects talk openly about heading to New York.Eventually, though, the driver is able to escape his captors by running from them into a gas station convenience store.Thanks in large part to information from the hostage, authorities track down the suspects. A chase ensues, during which the suspects toss explosives and exchange gunfire with police.
Tamerlan Tsarnaev dies after the gunfight, while his brother eludes authorities.

DaytimeBoston and surrounding communities are put on lock-down -- with schools closed, public transit halted and people ordered off the streets -- as authorities hunt for the surviving suspect.


7pm

After the lockdown is lifted, a resident goes outside to check on his boat parked in the backyard and notices blood inside. His tip leads to a large-scale law enforcement effort that culminates with the capture of Dzhokhar Tsarnaev.
