WASHINGTON — A 29-year-old man was convicted of second degree murder on Friday for the 2010 killing of a D.C. councilmember’s former intern.

Omare Cotton, of Washington D.C., was found guilty of killing 18-year-old Alonte Sutton after an argument that occurred when Sutton refused to give Cotton’s girlfriend a ride to work, according to a news release.

On May 7, 2010, police say Cotton — who was on parole — chased Sutton down Newcomb Street in southeast Washington with a knife. Sutton flagged a police officer at the time and the confrontation ended.

The next day, police say Sutton and his girlfriend returned to Newcomb Street where Sutton’s car was parked and attempted to change a tire on the car. Cotton then resumed the confrontation, chasing after Sutton’s girlfriend with a tire iron. As she fled in her car, Cotton got a gun and began chasing and shooting at Sutton, who ran into the woods, police say.

In the woods, Sutton stopped and cowered as Cotton shot him five times, police say.

Sutton’s body was found the next day. There were no eyewitnesses to the event and no DNA evidence at the crime.

Sutton had been an intern for D.C. councilmember Michael A. Brown.

Cotton was convicted of second degree murder, several firearm related charges and charges of assault with a dangerous weapon, threats and destruction of property. He faces up to 40 years in prison.
