Her death is being treated as a suicide, according to Smith.
Whitten was last seen Friday. Officials said she was on a family camping trip at Shaefer Heard Park when she disappeared while kayaking on West Point Lake, which is about 82 miles southwest of downtown Atlanta.
“Around 12:30 p.m., some campers saw her kayaking out in the water and shortly after that, a storm came through and around 2:30 her kayak was seen floating into the water with the paddle and the life jacket," Smith said.
Investigators from the sheriff's office, several other agencies and some civilian volunteers searched Saturday and Sunday for Whitten.
