LITTLE ROCK, Ark. (KTHV) -- Twenty-nine years ago this month, 55-year-old Patsy Clark was last seen getting in to a cab and was never seen again.

Five years later, Little Rock police closed the investigation, but David Clark, Patsy's son, never stopped looking for his mother.

"I hope, maybe one day, what I do have in my possession, will help me or someone else solve this”, said David Clark six years ago, when we profiled Patsy's story as part of our Cold Case series.

Monday, Clark got some help from a search team, who used cadaver dogs to help find his mother's remains.

"For 29 years now, we've been looking, and we have absolutely no leads, we have no clues, we have no crime scene”, he says.

Clark got the idea after he says the scientific evidence wasn't bringing him any closer. So he decided to think outside the box, and called Arkansas psychic, Carol Pate.

"I got that she was murdered. That she was abducted and murdered.” Pate says she's assisted in over 200 murder investigations and has never had a client as persistent and determined as David Clark. She says she hopes her visions will help law enforcement bring closure for both Clark and the entire community.

"I got some visions in that I saw a large oak tree, I got the road, I got approximately how far from the road, and which side of the road it was located."

Clark says Pate's vision brought him to a cow pasture, in what used to be a wooded area, near the intersection of Sardis and Alexander roads; 15 minutes from his mother's home. "This location is a possible place my mother could have been dumped or buried. We have searched the property and unfortunately we haven't come up with anything. But it's a process.”

He adds his life's mission is to find out what happened to his mother. And he has no intentions of giving up now.
