Date Posted: Saturday, June 14th, 2025

The Delaware State Police Homicide Unit has arrested 25-year-old Marcus Harris in connection with a fatal shooting that occurred early this morning in Millsboro.

On June 14, 2025, at approximately 2:00 a.m., troopers responded to a residence in the 24000 block of Rivers Edge Drive for a reported shooting. When troopers arrived, they located a 19-year-old man outside the residence suffering from gunshot wounds. Troopers rendered medical aid, but the victim was pronounced dead at the scene. Two other men were also found outside the residence with gunshot injuries. They were transported to an area hospital with non-life-threatening injuries.

Harris, identified as the shooter, was located inside the residence and taken into custody without incident.

A preliminary investigation revealed that the 19-year-old and two other men were at the residence with a female occupant who was acquainted with both the 19-year-old and Marcus Harris. While there, the 19-year-old got into an argument with the woman, who no longer wanted him or the other two men at the home. A physical altercation then occurred between Harris and the 19-year-old, during which Harris shot him. Harris then fired at the other two men. The woman was not injured during the incident.

Harris was transported to Troop 7, where he was charged with the crimes listed below, arraigned by Justice of the Peace Court 3, and committed to the Department of Corrections on a $480,000 cash bond.

Murder First Degree (Felony)
Attempt to Commit Murder First Degree – 2 counts (Felony)
