Dustin Michael Lee Marcum was 25 when he was found fatally shot inside a home on East Gray Street in the Phoenix Hill neighborhood of Louisville, Kentucky, on October 31, 2017. Police responded about 7:30 a.m. and pronounced him dead. He was known to family and friends as Duddy Michael and worked as a security guard.

Authorities identified and took into custody a male person of interest in his early 50s; police described Marcum and that man as acquainted and said they believed the two were friends and that an altercation preceded the shooting. Despite the arrest, prosecutors did not file charges against the person taken into custody, and the reasons for that decision were not publicly explained.

Marcum’s family and friends remembered him as golden-hearted. Does anyone have information about the events that led to the fatal shooting or the investigation that followed?
