On the morning of August 24, 1992, a passing motorist on Route 404 in Queen Anne, Maryland, stopped after seeing a man lying in a residence doorway. Deputies arrived about 7:15 a.m. and found 75-year-old Herman Dolly Callahan dead just inside his home from a single, close-range shotgun wound. Investigators said the shooting suggested the killer likely knew Callahan.

Callahan was a well-known local businessman who owned two cattle farms, rented to more than a dozen tenants, and was described as someone who started work early and could turn a dollar. Robbery did not appear to be the motive: $1,750 in cash and business notes were on his person. His 1985 GMC livestock truck was missing from the residence and later found abandoned at the National Guard Armory; why it was moved is unexplained and the murder weapon has never been recovered.

The case remains the only cold case homicide in Queen Anne’s County. No arrests or publicly named suspects have been announced, and investigators continue to seek information. If anyone knew Callahan, his routines, tenants, or observed the truck around August 24, 1992, please come forward with what was seen.
