WARNER ROBINS -- A recent tip did not pan out for the GBI related to the 1999 disappearance of an 11-year-old Twiggs County girl.

Rodney Wall, special agent in charge of the GBI office in Perry, said GBI agents spent about two hours Wednesday in Peach County using penetrative radar to look for “a pit” that was not found. Agents searched off Sherwood Drive in Byron, he said.

Wall said the GBI routinely checks out tips in relation to cold cases. He said this tip was about “evidence related to her disappearance” but did not include any reference to skeletal remains.

Teresa Melissa Dean vanished Aug. 15, 1999, after spending a Sunday playing outside her family’s mobile home along the Bibb County line in northwestern Twiggs County. The fairly rural area was surrounded by woods and clay pits.

The GBI’s website that features missing persons lists her as last seen on Lawrence Drive in Macon.

Dean is listed on the National Center for Missing and Exploited Children website at http://goo.gl/GTQEm. Anyone with information may contact the center at (800) THE-LOST.
