On the night of September 5, 1980, 33-year-old Eugene Gene Magnan was shot and killed outside the White Horse Bar in Denver during a large fight that spilled into the parking lot. Magnan, an electrician and a member of the Assiniboine Sioux Tribe, was walking outside as people were leaving when an unknown male fired a single fatal shot.

The Denver Police Department investigated, but no suspects have been publicly named and no arrests have been announced. The case remains unsolved and is now treated as a cold case. Little else is publicly recorded about who was involved or what led to the shooting.

If anyone remembers the White Horse Bar that night or has information about the altercation or the shooter, please come forward to the Denver Police Department.
