That autopsy was completed Thursday at the Medical University of South Carolina.
Allen did confirm that Cherol died of a single gunshot wound, information announced by the police department on Wednesday, the day Cherol's body was found in his 39 Pinecrest Way home.

He also said releasing the angle from which Cherol was fatally wounded could impact that investigation.
The South Carolina Freedom of Information Act exempts autopsy reports from the list of information and documents the public has a right to see.
In a two-sentence news release Friday morning, Bluffton police said the homicide investigation is "still active and ongoing."
Bluffton Police Maj. Joseph Manning also cited the ongoing investigation as the reason why a description of Cherol's injuries has not been released.
Anyone with information on Cherol's death can call the department at 843-706-4560.
Cherol was an active member of the local restaurant scene and co-owner of the recently closed Pepper's Old Town in Bluffton.
The May River Road restaurant had opened in early 2015 as a revamp of the original Pepper's Porch, replacing another restaurant that was also co-owned by Cherol, called Jack's Old Town.
