The former tag team champ, 60, said in a now-deleted Facebook post that he made a man “disappear” in his youth, according to TMZ.
“I was 13, working at Victory Lanes bowling alley buying weed from a f*g that worked there .. and he put his hands on me,” Jannetty wrote in the post.
“He dragged me around to the back of the building .. you already know what he was gonna try to do.”
Mr Jannetty, who according to his Facebook profile lives is from Columbus, said the man who allegedly attempted to assault him was “never found”.
He appeared to suggest that authorities should have checked a local river for the body. “They shoulda looked in the Chattahoocie River...[sic]” he said.
According to TMZ, Columbus detectives have launched a probe to look into Jannetty’s alleged murder confession.
“We are going to look into this,” a spokesperson told the publication.
“The first step will be seeing if we have any missing persons or unidentified remains cases that match the limited information in the post.”
The Independent has contacted Mr Jannetty and Columbus Police Department for comment.
