"Slatten was found guilty today of the federal offense of first-degree murder in the killing of Ahmed Haithem Ahmed Al Rubia’y, one of 14 unarmed civilians who were killed in a shooting by Blackwater guards that took place at Nisur Square in Bagdhad on Sept. 16, 2007," the statement said on Wednesday.
Slatten is one of four former guards who were involved in the incident. They opened fire on unarmed Iraqi civilians, including women and children, killing 14 people and leaving 17 others wounded.
"Slatten initially was retried on the murder charge last summer but a mistrial was declared on September 5, 2018, after that jury was unable to reach a verdict," the Attorney's Office said. "The current trial began on November 5, 2018, and the jury reached the guilty verdict on its fifth day of deliberations."
The incident with Blackwater guards sparked an international debate about the role of private security companies hired by the US government to work in war zones.
The private military company Blackwater, founded in 1997, was later sold and rebranded as Academi.
