The third suspect in Friday's Super 8 Motel homicide turned himself in late Tuesday, according to Police Lt. Debra Bohannon.
Trevon Brown turned himself into police at 9:35 p.m. He faces charges of murder, aggravated assault, possession of a firearm during the commission of a crime and criminal attempt armed robbery.
Police are still looking for Christopher Womack in connection with Troy Saunders' fatal shooting.
Brown is scheduled to be in Recorder's Court at 9 a.m. Thursday.
Neisha Jones and Mayson Gibson waived their initial hearing Monday morning. They face the same charges.
In the incident report, police said Jones, Gibson, Brown and Wommack intended to rob Saunders and the 21-year-old who was also in the car with the victim. Saunders was shot before he drove down Gentian Boulevard and wrecking his vehicle.
He was pronounced dead on the scene.
Saunders' homicide was the first in Columbus for 2014. On Saturday, 47-year-old Marvine Bailey was shot and killed during a drive-by shooting on Forsyth Street.
Correction: an earlier version of this story incorrectly identified Troy Saunders as Trey.
