Last time when Lester U-Banks escaped from an Ohio prison, the one time death row inmate seemed to just disappear.

We checked the computer to make sure that he was entered as a wanted fugitive and he wasn't even entered in the computer.

It's an escape, fell in any type of crime.

And when the manhunt resumed, some of Lester's relatives suggested the US marshals were wasting their time.

We're looking for this dude and he's been gone for what? 40 years? And it's like, you haven't found him yet.

What the hell makes you think you're going to find him?

I'm Sunny Austin from ABC News. This is Have You Seen This Man?

The End

By the looks of it, Lester U-Banks was thriving in Los Angeles. But police were hitting dead ends and growing increasingly frustrated.

They just weren't sure where their members of Lester's family who were in the dark about his whereabouts, or were there some who knew more and were engaged in a conspiracy of silence.

All to protect him?

Police weren't the only ones who wanted to know. Here's ABC News Senior Investigative Reporter Matthew Moss.

Those most distraught by Lester's disappearance, understandably, were the relatives of his young victim, middle school student Mary Ellen Deener.

Her family carried on in Mansfield, Ohio, bumping into members of the U-Banks family in church and around town, always wondering if they knew where he was.

One day in the early 90s, Mary Ellen's sister, Mertle Carter, had had enough. She wrote a letter that appeared in the local paper under the headline, Killer Still Free.

We asked her to read it for us.

You don't know me, but you know of my sister, Mary Ellen Deener.

She is a very bright and beautiful young girl who loved life as we all do at the tender age of 14.

But someone who had total disregard for another life decided to end hers.

She is no longer with us in the physical sense, but as long as her convicted murderer is free.

Her soul cannot be at rest.

Please, if you have any consideration for another person, consider this.
