FORT WAYNE, Ind. (AP): Authorities say an autopsy determined that a worker found dead inside a Fort Wayne antiques store was fatally beaten.

The Allen County Coroner’s Office says 58-year-old Robert Shimer of Fort Wayne died from blunt-force trauma to his head. Police say a customer found Shimer’s body about 5 p.m. Monday after noticing no employees around inside the Antiques on Broadway store near the city’s downtown.

Police Sgt. Mark Brooks tells The Journal Gazette and WANE-TV that investigators weren’t sure whether Shimer was attacked during a robbery and nothing was immediately found out of place in the store.

Police say investigators don’t believe Shimer was dead for long before being found, but they were searching for any witnesses.
