A Timeline Of Boston Marathon Bomber's Trial

Dzhokhar Tsarnaev's trial won't be postponed a second time. The jury was finalized just in time for the opening statements in the Boston Marathon bombing suspect's trial scheduled for Wednesday after it was originally delayed due to jury selection. On Tuesday, the day before opening statements were set to begin, a jury of eight men and 10 women was chosen for the high-profile trial on Tuesday. All 18 jurors are white, though one of the men is of Iranian descent. The panel will not know which 12 jurors will participate in deliberations and who will serve as alternates until the end of the trial, forcing all of them to pay attention to the proceedings that could last for months.

The bombing at the finish line of the Boston Marathon in April 2013 killed three people and injured more than 260. Tsarnaev, 21, pleaded not guilty to the 30 federal charges he faces, 17 of which carry the death penalty, in July 2013. A lot has happened since the initial bombing at the popular marathon that shocked the country almost two years ago. As the trial gears up to begin on Wednesday, here's a timeline of events that have occurred since the tragedy.
