Updated at 7:30 p.m. Aug. 4: Revised to include details from an arrest-warrant affidavit.
Authorities have arrested a suspect in a hit-and-run that left a 17-year-old boy dead last week.
Arlington police said Monday evening that Keshawn Sims, 22, had turned himself in to authorities in Hopkins County in connection with the death of Knoah Harlan.
Police said earlier in the day that they had obtained a murder warrant for Sims. He also faces a charge of aggravated assault.
Harlan was struck by a car the afternoon of July 27 in the 2100 block of Highbank Drive, near Bowie High School.
According to an arrest-warrant affidavit, Sims and another man had agreed to meet at the school for a fight because Sims had “engaged in a relationship” with that man’s girlfriend..
Witnesses said Sims arrived at the school and threatened to kill the group of people in another vehicle with the man. They got out of the vehicle and Sims drove down the street, made a U-turn and drove onto the sidewalk at the group, the affidavit says.
They got in the vehicle after Sims missed them, but he made another U-turn and appeared to be speeding directly at the vehicle, so they got out in an attempt to flee.
Sims struck Harlan and the man he had intended to fight, the affidavit says, then drove off without stopping. Harlan was pronounced dead at a hospital; the man suffered a broken foot.
It was unclear whether Sims had an attorney.
