CLEARWATER, Fla. — It's Florida Missing Children's Day, and Clearwater Police are using the remembrance to shed light on a cold case that dates back 20 years.

Eight-year-old Zachary Bernhardt was reported missing on September 11, 2000, from his bedroom at his Drew Street Apartment Complex.

Detectives say Zachary's Mom went for a walk before 5 a.m., and when she returned home she reported her son was not in his bed.

Since then police say there have been no leads or evidence that have led to answers.

"Time is always on our side," said Lt. Michael Walek with Clearwater Police. "It could take one hour.  It could take two hours.  It could take ten years.  It could take 20 years.  It could take 21 years.  Somebody out there knows something and somebody is going to come forward."

On Friday, Police met Zachary's family at the Drew Street apartment complex to raise awareness of the cold case with hopes that the attention will lead to new evidence or someone that may come forward with information.

"Just to keep his face out there.  Their photograph is what brings them home," said Zachary's Aunt Billie-Jo Jimenez.  "I want people to realize that, you know, in Walmart and when you go into the post office and these fliers are there, look at these kids, you know what I'm saying?  His picture is what's going to bring him home."

460,000 kids are reported missing every year in the United States.
