The indictment charge was DUI death.
Harmon, 20, of Cleveland was killed on U.S. Highway 61 near the Bolivar-Washington County line when she was struck by multiple vehicles traveling in the northbound lane.
Bolivar County Assistant Coroner Murry Roark pronounced Harmon, who was a 2010 graduate of Cleveland High School, dead on the scene.
According to the Bolivar County Sheriff's Department's dispatch log, a call came into the department at approximately 6:10 Saturday morning by a woman traveling north on U.S. Highway 61 stating that she had hit an object in the road and thought that it was a body.
Deputies were dispatched to the scene and immediately contacted the Mississippi Highway Patrol. In the meantime, the department received numerous other calls about the incident.
"I got the call at around 6:20 a.m.," said Sgt. Mike Mullins of the Mississippi Highway Patrol in a previous interview.
Mullins went on to say that when he arrived on the scene it became apparent that several different vehicles struck Harmon, including that of her boyfriend Rodney Shelton Fulgham.
"At this time it is difficult to tell which impact killed her," Mullins added.
Fulgham , 23, with addresses in Cleveland and Shaw, also called the 911-dispatcher to report the incident although he had traveled a significant distance after impact.
Mullins said Fulgham was taken into custody for questioning and later released.
The MHP and Bolivar County Sheriff’s Department worked on the investigation and staged an accident re-enactment.
Fulgham was bound over to the grand jury in February after a preliminary hearing at the Bolivar County Justice Court in Cleveland.
Justice Court Judge Harold Ward found there was probable cause for a grand jury trial based on the testimony of Mississippi Bureau of Investigation Agent Mark Steed.
Fulgham has been detained at the Bolivar County Regional Correctional Facility and at the time of the indictments were released from Bolivar County Circuit Clerk Marilyn L. Kelly no bond had been set.
Since Shelby Harmon’s death her mother Angie has been working diligently to bring awareness to domestic violence.
On Oct. 19 at 1 p.m. at Bear Pen Park, a walk-a-thon will be held for Shelby’s Voice, a non-profit organization that brings awareness to domestic violence.
"All proceeds will go to the shelters. There is one in Greenville that we've been working with and there's a new one we've been talking with in Batesville. "Unfortunately, there are no other ones any closer to the Bolivar County area," said Angie.
The cost to participate is $15 for an individual and $30 for a family or organization. Shelby's Voice T-shirts will be available at the walk-a-thon and if an individual registers and wants a T-shirt as well, the cost is $20.
"October is Domestic Violence Awareness month and we wanted to do something this year to remember and honor her and to reach out and help people that are going through the same thing that she went through," said Harmon.
"We feel like we have to be proactive and do something so we just can't sit by on our hands and do nothing," said Harmon.
