UPDATE (9:15 PM):
Officials with the Lee County Sheriff's Office say that they are ending the search for the night and will resume again in the morning.
Two people were swimming about twenty feet from the shore in the Kinchafoonee Creek when one person dove down and grabbed what they believed to be an arm.
The swimmers alerted the Lee County Sheriff's Office. The Lee County Sheriff's Office then called in the Lee County Fire Department Dive Team.
Spotlights have been set up and officials plan on searching through the night looking for this arm.
If an arm is found, further investigation will take place to find other possible body parts.
