Zachary Bernhardt was 8 years old when he vanished from an apartment complex in Clearwater on Sept. 11, 2000.
His mother reportedly went for a swim at their apartment complex in the middle of the night, leaving the door unlocked.
When she went to check on her son after returning, she noticed he was gone.
After 22 years, little is known about Zachary's disappearance and his case remains unsolved.
Bernhardt would be 30 years old today.
