Seventy-five-year-old Herman "Dolly" Callahan was gunned down in his own home on Aug. 24, 1992.
Herman Callahan's motionless body lay here on his front stoop when a passing motorist saw him.
Queen Anne County detectives discovered Herman's truck was missing from his home and found it parked at a nearby National Guard Armory. Cops say whoever drove the truck there must know something about the murder.
Herman's truck was located near the Armory, which can be seen in the lower right corner. His house is in the upper left corner of the photo.

Police discovered a large wad of cash and business notes on Herman's person, leading them to believe this was not a robbery.
Although Herman's home appears disheveled, police discovered nothing missing -- including the large number of prescription bottles on this table.
