Marc Koenig was 35 when his body was found in an alley in Denver on the afternoon of April 13, 2016. Officers responding to a report of an unresponsive person located Koenig inside a dumpster between the 3200 blocks of High and Race Streets. The scene provided few immediate leads.

An autopsy by the Denver Medical Examiner determined Koenig died of blunt-force injuries and ruled the death a homicide. Investigators described the alley as secluded and noted a lack of nearby surveillance footage, which limited evidence and witness development.

No suspects have been publicly identified and no arrests announced; the Denver Police Department continues to classify the file as open. If anyone has information about Marc Koenig, the location where he was found, or the afternoon of April 13, 2016, please come forward.
