A quiet Friday night at Cedar Creek Marina on Old Hickory Lake in Mount Juliet turned deadly on January 30, 2026. Calls to the Mt. Juliet Police Department reported a man threatening people on the docks; when officers arrived and searched the area, gunfire was heard. Responding officers found 45-year-old Robert Brogden with a gunshot wound; he was taken to a hospital and later died.

The gunman was identified as 45-year-old Gary Haley Jr., who was believed to be contained on a boat at the end of a dock. A prolonged standoff drew the department’s Special Response Team. Haley reportedly opened fire on officers and was shot and killed in the exchange. As the scene was secured, 52-year-old Matthew Jones was found deceased; a witness said Jones was also known as Nate and had helped fellow boat owners at the marina. The Tennessee Bureau of Investigation is handling the inquiry into motive and the full sequence of events.

If anyone knew Matthew Jones or has information about that night at the marina, please come forward to assist the investigation.
