MILLSBORO, DELAWARE — The community of Millsboro is mourning the tragic and untimely death of 19-year-old Andree’ Mosley Jr. of Ellendale, Delaware, who was fatally shot during a violent incident in the early morning hours of Saturday, June 14, 2025. The Delaware State Police Homicide Unit has arrested 25-year-old Marcus Harris in connection with the shooting and charged him with multiple felonies, including Murder in the First Degree.

The quiet streets of Millsboro were shattered in the early hours of that Saturday when gunfire erupted at a residential address located along the 24000 block of Rivers Edge Drive. According to Delaware State Police, troopers were dispatched around 2:00 a.m. following multiple emergency calls reporting a disturbance and gunshots. What law enforcement discovered upon arrival was a scene of devastation: three men lay outside the home, all suffering from gunshot wounds.

Tragically, the 19-year-old victim was pronounced deceased at the scene. Despite efforts by first responders and medics to revive him, his injuries proved fatal. The two other men were quickly transported to a nearby hospital for treatment of injuries described as serious but non-life-threatening. Their conditions have since stabilized, according to police updates.

The suspect, a 25-year-old man from Millsboro, was located at the residence and taken into custody without incident. Authorities confirmed that he was the alleged shooter and later charged him with one count of Murder in the First Degree, two counts of Attempted Murder in the First Degree, and three counts of Possession of a Firearm During the Commission of a Felony.

Gathering Turns Deadly

Investigators believe the fatal incident stemmed from a confrontation during a social gathering at the Rivers Edge Drive home. According to the Delaware State Police, the residence belonged to a female acquaintance of both the suspect and the victims. During the gathering, a disagreement began to brew—an argument that, for reasons still under investigation, turned violent.

The young victim, along with the other two men, were reportedly invited to the home by the woman. At some point, tensions escalated between the group and the suspect. According to police statements, the woman asked the three men to leave the residence, hoping to de-escalate the situation. However, before they could fully exit the premises, a physical altercation reportedly broke out between the suspect and at least one of the men.

What followed was an eruption of violence. Police allege the suspect retrieved a firearm and began shooting, first striking the 19-year-old victim and then firing on the other two. After the shots were fired, the suspect remained at the scene and was taken into custody without resistance by responding troopers.

The woman involved in the initial gathering was uninjured and cooperated fully with investigators.

Shock and Grief Ripple Through the Community

The sudden and violent death of a teenager with his whole future ahead of him has sent shockwaves through the communities of Ellendale and Millsboro. Vigils have begun forming at the site of the incident, where friends, neighbors, and relatives have laid flowers, candles, and handwritten notes in remembrance.

For those who knew the victim, the loss is not only personal but deeply emotional. Friends describe him as kind, easy-going, and full of potential. He had aspirations—goals that extended beyond his small hometown. Whether it was a career in business, sports, or music, he was someone who made those around him believe he would achieve something meaningful.

“He was the kind of person who brought people together,” one friend shared. “He had a calm about him, a real warmth. You could be having a terrible day, and he’d say something to make you laugh or feel better. That’s who he was.”

Family members have been equally devastated by the news. In a statement released to local media, they described the 19-year-old as a loving son, a protective brother, and a loyal friend. “He had so much promise,” a family member said. “He never deserved this. No one does.”

Investigative Developments and Legal Proceedings

The Delaware State Police Homicide Unit has taken the lead on the investigation, collecting evidence from the scene, including shell casings, surveillance footage, and witness statements. Authorities have confirmed that the weapon used in the shooting was recovered and is being tested as part of the forensic analysis.

The suspect has since been arraigned at Justice of the Peace Court #3 and is currently being held at Sussex Correctional Institution on a $480,000 cash-only bond. Legal experts anticipate a lengthy judicial process, which may include mental health evaluations, a potential grand jury indictment, and, depending on outcomes, a trial that could take many months to unfold.

Prosecutors have not yet indicated whether they will pursue the maximum penalty under Delaware law, but given the severity of the charges and the community impact, the case is expected to receive considerable attention.

Violence in Smaller Communities

Though Delaware is not known for high rates of violent crime, this tragic shooting underscores a growing concern: that even in close-knit, rural or suburban communities, disputes can quickly spiral into deadly altercations when firearms are involved. Law enforcement officials and civic leaders have expressed concern about the increasing frequency of gun-related violence across the state.

“Millsboro is a peaceful town, and we are devastated by what happened,” said a city official. “But this tragedy reminds us that violence does not discriminate by location. We have to be vigilant in providing resources for conflict resolution and mental health support, especially for our young people.”

Community advocates are using this tragedy to call for stronger preventative measures, including:

• Conflict mediation and de-escalation programs aimed at youth and young adults
• Expanded access to mental health services and crisis intervention hotlines
• Gun safety education and safe storage outreach programs
• Increased police and community engagement in underserved neighborhoods

Local nonprofits have also stepped in, offering counseling services to friends and classmates of the deceased. Several churches in Millsboro and Ellendale are hosting community healing sessions and open discussions to help people process the grief and trauma left in the wake of the shooting.

Remembering a Life Cut Short

Even as legal proceedings move forward, the community’s focus remains on honoring the life that was lost. Friends and family are organizing a candlelight vigil at the town’s central park, scheduled for the upcoming weekend. Plans are underway for a memorial scholarship to be established in the young man’s name, aimed at helping other local youth pursue higher education or vocational training.

“He believed in hard work and believed in his friends and family,” one cousin remarked. “He never gave up on the people he loved, and we’re not going to give up on his memory.”

Local schools have also responded. The young man’s former high school has announced plans to dedicate a section of the school’s annual yearbook in his honor. Faculty members have spoken out, recalling his kindness and curiosity in the classroom.

A Call for Justice and Healing

As the case proceeds through the courts, the community is navigating the difficult balance between grief and resilience. There is a shared desire for justice—an acknowledgment that the person responsible for this senseless violence should be held accountable. Yet, there is also a call for healing and unity, for communities to come together and ensure such tragedy is not repeated.

“We have to be better,” said one community member. “We owe it to his memory to make sure this doesn’t happen again—to any other family, to any other mother, to any other town.”

In Closing

The loss of a 19-year-old under such violent and tragic circumstances has cast a long shadow over Millsboro and beyond. It is a loss felt not only by those who knew him but by anyone who believes in the right to grow up, to dream, and to live without fear. His death is a stark reminder of the fragility of life and the urgent need to address the root causes of violence—before they escalate into irreversible heartbreak.

In the end, the community’s tribute to this young man will not only be in flowers or words but in action—in building safer streets, stronger bonds, and a future where no family must endure such a loss again.
