Victims to relive horror of marathon bombing as trial begins
In the two years since twin bombs tore through crowds at the Boston Marathon finish line, the case against suspect Dzhokhar Tsarnaev has focused on arguments over where his trial should be held, who should sit on the jury and what evidence prosecutors should be allowed to use.
But starting Wednesday, a day after a jury was selected, the focus will shift dramatically from the legal process to the harsh reality of what happened that day: the explosions, the screams, the chaos and the blood.
Prosecutors are expected to present graphic images of the carnage caused by the bombs, including a surveillance video that authorities say shows Tsarnaev placing a backpack just feet from 8-year-old Martin Richard and his family. The boy died in the explosion.
The bombs set April 15, 2013, killed three people and injured more than 260. At least 16 people lost limbs.
