Eighteen-year-old Mary DeLaughter was shot and killed on the night of June 27, 1976, near the White Spot Diner in the 600 block of East Colfax in Denver. She was with a friend when a car carrying several men pulled up, demanded that the two get into the vehicle, and opened fire when they refused. Officers in a nearby parking lot heard the shot and found Mary’s body.

Investigators learned Mary had been a runaway from another state and had been living in various places around the Capitol Hill area. She was also known as Mary Panzan and Mary DeLauther. Despite a witness to the encounter, the men in the car were never identified and no arrests have been made; the case remains cold.

Does anyone who knew Mary, or who lived around East Colfax in June 1976, have information that could help bring new leads?
