Tsarnaev, who had been largely emotionless throughout his trial, appeared to weep when his relatives testified on May 4, 2015, during the sentencing phase of the trial. The defense characterized life in prison as a harsh punishment, and did not try to convince the jury that Dzohkhar's actions deserved anything less. The prosecution argued that death by lethal injection was a more appropriate punishment. On May 15, 2015, the jury recommended that Tsarnaev be sentenced to death by lethal injection on six counts of the indictment. The death sentence counts were related to the setting of the second bomb, which killed Lu and Richard. The counts related to the deaths of Campbell and Collier did not result in death sentences; the jury believed that Tamerlan Tsarnaev had responsibility for the first bomb, which killed Campbell.
