There are some new clues coming to light in a 20-year-old cold case.
Kentucky State Police say investigators found more clues in connection to the murder of Gregory Back.
He went missing in 1989 and his body was found last month.
Police drained the pond where Back's body was found in the trunk of a car. They say that several clues relating to the murder turned up in the pond.
Police are asking for help from the public for any more clues in the case.
