A District man convicted in the slaying of a former D.C. Council intern was sentenced Friday to more than 36 years in prison, authorities said.

Omare Cotton, 30, was convicted in December of second-degree murder while armed, the U.S. attorney’s office said. According to authorities, Cotton got into an argument with Alonte Sutton on May 7, 2010, then tracked him down and shot him the next day.

Sutton, an 18-year-old Ballou High School senior, had worked as an intern for D.C. Council member Michael A Brown.

His body was found in a wooded ravine in the 200 block of Newcomb Street SE near the St. Elizabeths Hospital campus. He had been shot several times, authorities said.

Cotton was arrested days later.
