A 33-year-old man in central Florida died while trying to save his wife who was struggling in the rough water of a lake, investigators said Tuesday.

Sara Diggs, 37, had trouble staying afloat as soon as she entered the water from a ladder off a boat on Lake George on Sunday, The Daytona Beach News-Journal reported.

Her husband, Norman Diggs III, went into the water after her and also began struggling, the Florida Fish and Wildlife Conservation Commission added.

The couple's friend Gary O'Brien was on a nearby boat. He reportedly jumped in while others started calling for help.

O'Brien was able to get Sara Diggs to safety, but wasn't able to help her husband. Officials found Diggs' body Sunday night, some five hours after he sank into the water.

Strong winds had hit the lake at the time of the incident. Norman Diggs wasn't wearing a personal flotation device, investigators added.
