The Kentucky sheriff looking into the theft of barrels filled with Wild Turkey bourbon says the case involves significantly more stolen bourbon than previously thought and will eventually result in multiple indictments.

Franklin County Sheriff Pat Melton says investigators uncovered a new "major development" Monday that will delay presenting the case to the grand jury in Frankfort. Melton canceled a press conference set for Tuesday after the new development and wouldn't talk about it.

So far, one person has been arrested in the case of at least five stolen Wild Turkey barrels.

Melton says the case could go before the grand jury as soon as next week.

The state attorney general's office has assisted in the investigation.
