CLEVELAND, Ohio - It was Friday, July 11, 1969 at the Society National Bank in Downtown Cleveland. 20 year old vault teller Theodore Conrad left for the day, taking with him $215,000 in a brown paper bag.

That's worth nearly $1.4 million in today's money. 
Conrad left, and literally fell off the face of the earth. 

"We were able to track him from Cleveland to Washington Reagan National Airport to Los Angeles, and the last stop we know of was in your great state of Hawaii and we believe there is somebody on that island that either knows him, knows of him or had a brief stint relationship with him," David Siler, Deputy U.S. Marshal with the Northern Ohio Violent Fugitive Task Force said in a phone interview.

Three months after the robbery, an Ohio couple stuck up a conversation with a young man in a bar at the Princess Kaiulani Hotel in Waikiki. Law enforcement believe that man was Conrad.

"As soon as they mentioned Cleveland, Ohio, he got up, said oh excuse me,I have to use the restroom, he departed," Siler said. 

He never returned.

When the couple got home,  they recognized him from stories on the crime.

Ohio law enforcement have never given up.  But they are hoping new technology might help them finally solve this case and the U.S. Marshals have turned to Hawaii for help.

They believe he lived in Hawaii at one time or perhaps still does.

Because in 1969, that young man told the couple he was living in an apartment close to the zoo
"He had an apartment. Apparently, he was renting that apartment so if he was renting that apartment, that means he made contact with someone, a landlord, somebody and he was paying cash obviously for his apartment," Siler said. 

"Everything is one clue away. Everything is about one tip away. There's somebody out there that Conrad has made contact with over the years. Hopefully that one person is going to give us that one last piece of the puzzle so we can finish this and get us to the front door and have a conversation with Mr. Conrad and take him into custody without any incidence," Siler added.
