The acts of terrorism known as the Boston marathon bombings took place on April 15, 2013.
Much pain and anger is still felt by those who lost loved ones and possessions to the bombings, even two years later.
Dzhokhar Tsarnaev was found guilty of 30 charges, including murder, in the first phase of his trial. The second phase, which will determine if he receives the death penalty, started on April 21. During this trial, some of the victims and their families demanded his death.
