David J. Duncan, 45, was fatally shot outside his Independence, Missouri, home on the morning of September 18, 2015. He had arrived at his residence in the 16900 block of East 41st Terrace South around 9:45 a.m. when a gunman exited a vehicle and fired multiple rounds from a rifle in Duncan’s front yard. He was taken to a local hospital and later died of his injuries.

Investigators initially searched for a silver Cadillac seen leaving the area, but later found the assailants had used a different vehicle. Evidence including surveillance footage and other material showed DeMarko L. Collins had staked out Duncan’s home for two days and was the driver of an orange Dodge Journey that waited for Duncan to return; the attack was then launched. Collins, a convicted felon on parole for a prior robbery conviction, had a search warrant executed at his apartment after the murder and a stolen firearm was recovered.

Collins was not charged with murder in state court, but federal prosecutors brought firearms charges. At his 2017 federal sentencing a judge found sufficient evidence linking Collins to Duncan’s murder and applied a sentencing enhancement; Collins received 18 years in federal prison without parole.

Did anyone in the area see the orange Dodge Journey or the silver Cadillac around 9:30–10:00 a.m. on September 18, 2015?
