LOUISVILLE, Ky. (WDRB) -- Bones were found at a vacant lot in Elizabethtown, according to police.

Ground-penetrating radar and cadaver dogs were brought in last week to search the lot along E. Railroad Avenue. Officers were called to the area after a tip that human remains may be buried there -- but the search was called off.

Now, they say small pieces of bone were found. They are analyzing them to determine if they are human or animal.

Pamela Rhinehart is the woman who tipped off police. She says on February 1,  her uncle, 60-year-old Larry Sherrard, confessed to her hours before he died.

"And he looked at me and said, 'I don't want to go to hell," said Pamela Rhinehart, the woman who allegedly heard the confession. "I said, 'What are you talking about?' He said, 'I killed two men.'"

"It surprised me that he told us, but it didn't really shock us," said Kathy Sherrard, Larry Sherrard's sister-in-law.

Rhinehart gave WDRB more details about what she says her uncle told her about the alleged murder: "[The victim] had screwed him in a drug deal and he had shot him and him and two other gentleman had dug up the concrete, buried the body and re-concreted over top of it. They had put some lime or lye down over tops of it to keep the smell from coming out."

Kathy Sherrard says that wasn't the only murder he confessed.

She says a year before, when he was released from prison on drug charges, he had also confessed to shooting someone in 1989.

"The guy that was with him cut the carpet up around him and they rolled him up in carpet and put him in the trunk of the car and took him to Hal Valley and dumped him in a cave," said Kathy Sherrard.

A detective with the Hardin County Sheriff's Department tells WDRB that they reopened a case last week, involving a man's body that was found in a cave in 1989. They are investigating to see if it's connected.

While family members wait for answers, they're just hoping the information will be helpful to police.

"No matter whether those people that he killed over a bad drug deal were drug dealers or not, they were somebody's somebody and somebody needed to know about them," Rhinehart said.

And authorities say the results of the analysis on the small pieces of bone will determine the direction of this investigation.
