ATLANTA -- Authorities are looking into the 1996 disappearance and death of a Tucker woman to see if there is a connection to Barton Corbin, a Dacula dentist accused of killing his wife and a former girlfriend.

Harriet Gray, 56, disappeared from her home in September 1996 in what appeared to be an abduction. Her body was found in her car at the bottom of Lake Tuscaloosa in Alabama in December 1997.

Her case has been treated as a homicide, said Lt. J.R. Simpson of the Tuscaloosa, Ala., Police Department. No arrest had ever been made in the case.

"We are looking into the case we had over here," Simpson said Friday. "And we're looking at other cases in other jurisdictions."

Gray worked for a dentist who is a former partner of Corbin's, and relatives said she and Corbin were acquainted.

Corbin, 41, has been indicted on charges related to two apparent homicides -- the 1990 death of Dorothy "Dolly" Hearn in Augusta and the Dec. 4 death of his wife, Jennifer Corbin, in Buford. He has denied he was involved in both deaths.

Sgt. Scott Peebles, lead investigator with the Richmond County Sheriff's Department in the Hearn case, said Alabama authorities have contacted the district attorney's office in Augusta about the Gray case.

Peebles said he understood Gray may have worked for Corbin.

"At some point we're going to have to investigate if (Corbin) was responsible for her, too. We're going to look at any similarities," Peebles said. "This is something we're going to look at and discuss with Alabama authorities."
