Dylann Roof, was found guilty on Thursday on multiple federal charges after taking the lives of nine parishioners at a black church in Charleston, SC in 2015. Roof was found guilty on all 33 counts he faced.
Roof will find out his sentence for the crimes early in 2017.
Roof was found guilty on 12 counts of hate crimes, 12 counts of obstruction of religion and nine counts of use of firearm to kill.
Deliberations began Thursday afternoon in the Roof murder trial after attorneys made closing arguments.
Shortly after deliberations began, the jury asked to again watch the video in which Roof confessed to two FBI agents. Specifically, the jury wanted to see the portion where Roof was unsure of how many people he had killed.
Roof, 22, a self-declared white supremacist, has admitted to last year's killings at Emanuel African Methodist Episcopal Church. Now, after watching an on-camera confession by Roof, jurors could decide not just whether he's legally guilty, but also whether he should get the death penalty.
"He needs to be held accountable for every bullet," Assistant U.S. Attorney Nathan Williams told the jury, emphasizing what he said was the depth of Roof's hatred.
"The parishioners could not have seen the hatred in his heart," Williams said. "He sat and waited until they were at their most vulnerable."
Family members of the victims sobbed as Williams spoke.
Defense attorney David Bruck said Williams was correct about the events.
"Why, why did Dylann Roof do this?" Bruck said. "What was the explanation?"
Bruck asked the jury to "look beyond the surface" and to ask, "Is there something more to this story?"
The closing arguments come after a week of dramatic arguments and chilling testimony about the June 2015 massacre.
Prosecutors presented Roof as a "cold and calculating" killer. Jurors saw a witness whose son was killed sobbing on the stand. They heard an FBI agent read a series of Roof's racist writings. And they watched a video of Roof laughing after admitting he killed the victims.
The defense did not call any witnesses, and Roof did not testify.
