A man who ran over a motorcyclist in Gwinnett County last year without stopping will spend the next five years in prison, the district attorney's office said Monday.

Jacob O’Reilly pleaded guilty to homicide by vehicle and failure to return to the scene of an accident in the July 26 death of 24-year-old Scott Moseley.

A Gwinnett judge sentenced O’Reilly to 15 years, but O’Reilly will only serve the first five years in confinement, according to the office of Gwinnett District Attorney Danny Porter.

Moseley was riding his motorcycle near Buford last summer when he attempted to make a left turn from Camp Branch Road onto Gravel Springs Road, Gwinnett police Cpl. Michele Pihera said at the time.

Moseley struck a raised median and was ejected from his motorcycle. An “unknown vehicle” hit Moseley as he was in the roadway “without stopping to render aid or contact police,” Pihera said.

Moseley, she said, “likely died as a result of being struck by the vehicle.”

Police found the suspect vehicle in the parking lot of the Mall of Georgia, and the car was impounded, police said.

Investigators interviewed O’Reilly, the car’s owner, and arrested him at his home in Auburn.
