Richmond County investigators and forensic technicians are in Gaffney, South Carolina, trying to find out how a man from that area ended up in Augusta in the Savannah River.
On Tuesday, a fisherman found Ian Mosley's body at the Lock and Dam in the Savannah River.
The Gaffney, South Carolina man suffered a gunshot wound to the head.
Richmond County investigators have traveled to Mosley's hometown to try and find out how the 25 year old ended up in the river.
"We are back tracking from that point to see what may have led him to this area," says Sgt. Richard Roundtree of the Richmond County Sheriff's Office.
Investigators are doing a background check, talking with friends and family and searching Mosley's apartment for more clues.
"That's why we indeed sent a team of investigators to that area, to follow leads in a more productive area," Sgt. Roundtree says.
Mosley was last seen in his white Lexus in Gaffney. The car was found on Thursday by investigators.
"That vehicle has been located in North Carolina," says Sgt. Roundtree. "That vehicle is in the process of being processed."
Following leads from the victim's background will tell officers if Mosley had ties to this area.
"Everything according to what we have now ties him back to the Spartanburg or the Gaffney, South Carolina area," says Sgt. Roundtree.
Another fisherman claims to have spotted an arm in the same area where Mosley's body was found on Wednesday.
An extensive search of the river by helicopter and jet skis turned up nothing.
Sgt. Roundtree says there are no missing person reports connected to this case.
In the meantime, investigators have not found a motive in Mosley's murder.
