On September 10, 2000, Leah Hackett put 8-year-old Zachary Bernhardt to bed at 11pm.

She would struggle to sleep herself, so she went out for a walk and the swim.

When she returned, Zach was gone.

Over the years, fingers would point at Leah as being the person responsible for Zach's disappearance.

This would be until a local pedophile would take credit for taking the boy.

Then a year after Zach was last seen, a photo was discovered showing a young blonde boy

bound with his wrists and ankles bound with duct tape.

The boy looked eerily similar to Zachary Birdhart, but it's been never confirmed to be

the case.

Zach's case being the longest running Amber alert for the state of California.

This is Zach's story.

The eight-year-old Zachary Bernhard disappeared from his bedroom in this apartment complex

behind me 20 years ago.

Loved ones say the lack of closure makes the years even harder.

It's like an emotional roller coaster. You go up and down, up and down a lot.

Family members have never stopped looking for Zachary Bernhardt and time hasn't made the pain any easier.

Here we are at the 20 year mark and still no closer to knowing anything more about his disappearance than we do it from the first day that he disappeared.

Clearwater police say Zachary's mother called to report him missing just before 5 a.m. on September 11th, 2000.

Investigators say the disappearance is suspicious.

He didn't even have a working bicycle. So to say that somebody at eight years old gets up and just leaves at 447, I think could be outside the norm.

Over the last two decades, police have worked hard, pouring over evidence and following up on hundreds of leads.

But there has been no trace of Zachary.
