Authorities are not sure why someone ransacked two county-owned boats early this week.

Forsyth County Sheriff’s Sgt. Chris Shelton said the incident occurred sometime between Sunday afternoon and Tuesday morning on a dock at Port Royale Marina in northeastern Forsyth.

He said someone removed a fuel can, crime scene tape, gloves and a body bag from the Forsyth County Fire Department’s pontoon boat and left them on the sheriff’s marine patrol boat.

“That’s the first time that’s ever happened to us or the fire department,” Shelton said.

“Somebody went through all the compartments and put everything in the center of the boats. They either got scared off or it looks like they were going to come back and take whatever they piled up.”

Shelton said none of the electronics on the boats were disturbed.

Authorities are keeping a close eye on the vessels, which have since been moved to a more secure location.

Forsyth County Fire Capt. Jason Shivers explained that the fire department uses its boat for rescues, dives and recoveries on Lake Lanier.

He said someone went through medical supplies and rescue equipment, but there were no signs of damage.

“Any kind of criminal investigation will be conducted by our internal affairs division in conjunction with the sheriff’s office,” Shivers said.

Shelton said when caught, the suspects could face criminal damage to property and theft charges.
