"We have not ruled out anything at this point as the autopsy will hopefully provide us with more information as well as the interviews and other investigative leads we are following," Pat Morgan of GBI told WRDW-TV.

Clark Hills lake is located in Northeastern Georgia, near the border with South Carolina.

A little over a year ago, friends Eynn Wilson and Edward Kirk drowned in the same area during a boating excursion with friends and family members. Shontover Kirkland, 32, was charged with reckless conduct and involuntary manslaughter and pleaded guilty in the case last week.
