A jury has convicted Dylann Roof of the racially motivated killings of nine black church members in South Carolina.
The 12 jurors reached their verdict in less than two hours finding the 22-year-old guilty of all 33 charges against him.
The white supremacist now faces the death penalty of he was convicted of hate crimes, firearm violations and obstructing the exercise of religion for those he shot and killed during a Bible study group in Charleston last year.
The jury will reconvene next month to decide whether he should get the death penalty or be sentenced to life in prison.
Roof stared ahead as the verdict was read, much as he has throughout the trial.
The jury delivered its verdict after hearing six days of testimony in Charleston, a city on edge in recent weeks as two racially charged trials played out in courthouses across the street from each other in the heart of downtown.
A state murder trial against a former North Charleston police officer who shot and killed a black man fleeing a traffic stop last year ended on December 5 in a mistrial after jurors deadlocked.
Whether Roof carried out the mass shooting that intensified the debate about race relations in the United States was not in dispute.
But his defence lawyers, hoping to spare him from execution, asked jurors to consider what factors had driven Roof to commit the senseless act and suggested he might be delusional.
The defence did not call any witnesses after the trial judge blocked them from presenting evidence of Roof's mental state during the guilt phase of the trial.
During closing arguments on Thursday, prosecutors dismissed the defence's position and said Roof's guilt had been proved "beyond any doubt, much less reasonable doubt."
"He must be held accountable for each and every action he took inside that church," Assistant US Attorney Nathan Williams said. "For every life he took."
