Special Report: Where is Cleashindra Hall?

In 1994, former Arkansas Governor Bill Clinton is president.

In hoops, the Razorbacks win their first national championship.

And in Pine Bluff, Cleashindra Hall prepares for her high school graduation.

"[She was] funny, sort of nerdy because she liked to read,” Hall’s mother Laurell Hall said. “She liked to talk on the telephone as any teenage girl"

Clea sets her sights on going to Tennessee State University and becoming a pediatrician.

"She was not only studious but the kids at school liked her," Laurell said.

Monday, May 9, 1994. Clea gets a call from her part-time job.

For about a year, Clea worked for a grant writer who ran an office out of this home. Laurell said she always dropped her daughter and made sure she made it in before driving off. But on May 9, 1994, it was the last place she saw her daughter.

"I didn't think anything was wrong when I dropped her off," Laurell said.

Clea never returned home from work.

"I'm thinking like a parent,” Laurell said. “I'm waiting for her to come in because you're in trouble. You didn't tell anybody and it's late so I stayed up all night looking for her."

Search efforts began immediately.

After 17 and a half years - still no Clea.

"Do you think Clea is alive? I'm praying that she's alive,” Laurell said. “In my heart she's alive and so until something is proven different it's going to be that way."

"It's quite obvious to me that something terrible happened to Clea," Criminal Profiler Glenn Owen said.

This even baffles Owen. Like Walther Sherman in "The Finder," Owen looks for missing persons.

In this real life disappearance, Owen believes a man took Clea against her will, killed her, and then dumped her body in a remote area.

"Whoever abducted Clea, took Clea that night knew her,” Owen said. “This isn't a stranger abduction. He knew her, she trusted him and that's how he was able to get into her safe zone."

Owen profiles the offender to be an educated man, with some years of college.

A sociopath, an anti-social person, who keeps up with the investigation and appears to have an interest in the case to keep suspicion away.

"These offenders are very brutal in the way of killing," Owen said.

He admits his profile is just a hypothesis.

"These cases can be worked through circumstantial evidence if people will help with tips and the information they desperately need in this case," Owen said.

And that's what the halls hope these ribbons and flyers on the front of their house will do, nudge someone to talk. To put an end to a unforgotten, unsolved mystery.

"You'd only have to be a parent or a relative of a person that's missing to understand what we've gone through and I just can't believe you'd still sit there after all this time and not tell us anything," Laurell said.
