A Mexican man extradited to the U.S. this week has pleaded not guilty to charges in the slaying of a Border Patrol agent in Arizona eight years ago.

Court records show Heraclio Osorio-Arellanes entered his plea during a Wednesday afternoon arraignment in U.S. District Court in Tucson. Trial was set for Sept. 11.
Osorio-Arellanes had awaited extradition since his arrest by Mexican authorities on April 12, 2017. 
He was among seven people charged in the death of Border Patrol Agent Brian Terry, who was killed Dec. 14, 2010 when he and other agents encountered a gang preying on smugglers north of Nogales, Arizona.
Three of six other defendants charged in the case have pleaded guilty and two were convicted following a jury trial. Another defendant has not yet been tried.
