Wednesday, May 11, 2011 was your typical day for Jim Pitzen.

He dropped his son, Timmothy, off at school and his wife, Amy off at work and continued to work himself.

When he returned to Timmothy's school to pick him up, Timmothy wasn't there.

Confused, he asked who signed him out, only to find...it was Amy.

Hours turned into days until police finally found Amy - in a motel, dead from an apparent suicide...with Timmothy nowhere to be found...and a cryptic note left behind.

Over 20 years later, the Pitzen family still holds out hope they will find him.

Listen now for all the creepy details of this case.
