A 30-year-old man who was charged with the killing of D.C. intern Alonte Sutton, 18, was sentenced to 36 and 1/2 years in prison.
Omare Cotton was charged over the killing of Sutton, who was an intern for U.S. Attorney Ronald C. Machen Jr. He was convicted by a jury in December 2011 of charges of second-degree murder while armed, assault with a dangerous weapon, threats, destruction of property, and various weapons offenses.
Following his release from prison, Cotton will be placed on five years of supervised release.
Authorities said that Cotton got into an argument on May 7, 2010 with Sutton after he refused to give Cotton's girlfriend a ride to work.
When the argument escalated, Cotton slashed the tires on Sutton's car and chased him with a knife, authorities say. When Sutton flagged down a passing police car, Cotton, who was on parole at the time for an armed robbery in Maryland, fled from the police.
The next morning, Cotton shot Sutton when he was trying to change his tires, authorities say. Cotton fled the scene, changed his appearance, and took steps to hide the gun from police detection, evidence shows.
