Andrew Duncan, 31, was shot and killed in Boulder, Colorado, on February 1, 2016. He was found with multiple gunshot wounds in the morning in the 4400 block of North Broadway and was taken to a nearby hospital, where he died shortly after. An obituary lists his name as Andrew Tyler Duncan and gives a date of death as February 5, 2016.

Investigators arrested two people in connection with the shooting. Cody Nelson, then 51, was charged with first-degree murder and prohibited use of a weapon; Miriam Nayeh, 31, was charged with accessory to first-degree murder. Court testimony described Duncan visiting Nelson’s home because he was concerned for the mother of his unborn child, whom he believed was using heroin at that residence, and the shooting occurred as Duncan was leaving the house. Video shown at trial reportedly captured Nelson firing at Duncan and continuing to shoot after Duncan had fallen. Prosecutors said there was no evidence Duncan posed a threat; the suspects claimed he had been abusive.
