In the early morning hours of September 28, 2009, a call reporting a shooting brought Denver police to the 2500 block of East 40th Avenue. Officers found 53-year-old Barbara Irish in a parking lot; paramedics pronounced her dead at the scene from an apparent gunshot wound. An autopsy confirmed the cause of death as complications from a penetrating gunshot wound to the head and the manner of death was ruled a homicide. Barbara was white.

Investigators from the Denver Police Department and the Denver Office of the Medical Examiner worked the case, but no arrests were ever made and the investigation grew cold. Her death left grieving family and friends, including a cousin who remembered her as a first best friend and more like a sister. The case remains open and unsolved and is listed on the Colorado Bureau of Investigation’s Cold Case Files and the Denver Police Department’s cold case list.

Does anyone who was in the 2500 block of East 40th Avenue on the night of September 27–28, 2009, or who knew Barbara, have information that could help bring answers?
