A search for a 3rd Infantry Division soldier, who went missing off the coast of St. Simons Island while swimming Sunday, was suspended Monday.

The Brunswick Coast Guard station reported the search for Army Staff Sgt. Calvin Leblanc, 30, had been unsuccessful.

Fort Stewart Public Affairs said the Minot, N.D., resident was a combat engineer assigned to Headquarters and Headquarters Company, 4th Infantry Brigade Combat Team. He arrived at Fort Stewart on March 20. He had deployed three times, returning from his last deployment in October 2009.

Coast Guard Station Brunswick reported Leblanc was swimming with his family near east St. Simons Beach. His wife reported the accident, saying the sergeant got caught in a rip current and had been swept out to sea. Watchstanders received notification at approximately 5:20 p.m.

The Coast Guard launched a boat rescue crew from Brunswick and Coast Guard Air Station Savannah launched an air rescue crew at approximately 5:28 p.m.

Fort Stewart also reported the Georgia Department of Natural Resources, with support from Glynn County law enforcement, helped with the search with divers, site scan sonar, helicopters and all-terrain vehicles.

The chain of command, along with the unit chaplain and the American Red Cross, were with the family on St. Simons during the search.
