The man whose body was found Friday in a Scott County creek has been identified as Jorge "George" Zamudio Flores, 29, said Scott Coroner John Goble on Monday.
The name was released after relatives in Mexico were notified, Goble said.
Kentucky State Police and the Scott County Sheriff's office are investigating his death as a homicide, Goble said.
Scott County Sheriff Tony Hampton said Monday afternoon that Flores was last seen alive on Sept. 4 around 10 p.m. in the Frankfort area. Authorities still are not releasing details such as the cause of death, the sheriff said.
"We are working on some leads ... and trying to develop some suspects," Hampton said. "We'd like to get somewhere with that before we release any more information."
Hampton said investigators continue to believe that the theft of Flores' truck might be a factor in his death. The blue 2002 Chevy Avalanche is missing and is considered stolen, the sheriff said.
"We are hoping that law enforcement may find it, or hopefully stop it with someone in it, because we do believe it could be connected to this crime," Hampton said.
The truck has a Kentucky license plane, 214NAY. Anyone who sees it should contact local police immediately, Hampton said.
The truck has been missing since Flores was last seen, according to the sheriff.
Flores lived on Owenton Road,in neighboring Franklin County, where he had a cousin, authorities said. He did not have children, according to Hampton.
Flores' body will eventually be returned to Mexico, Goble said.
