A murder investigation is under way following the tragic death of 27-year-old Sarah Montgomery, a pregnant mother of two, in Donaghadee, County Down. The Police Service of Northern Ireland (PSNI) received a report at approximately 2.15pm on Saturday about an unconscious woman with a serious injury at a house in the Elmfield Walk area. Upon arrival, officers discovered Ms Montgomery inside the home. Despite the efforts of emergency services, she was pronounced dead at the scene.

The case has rocked the quiet seaside town and sent shockwaves across Northern Ireland, as communities mourn yet another young life lost to violence.

Victim Identified as Sarah Montgomery

The woman has been formally identified as Sarah Montgomery, a young mother with two children and another on the way. PSNI confirmed she was pregnant at the time of her death. Friends and family have paid tribute to Sarah online, describing her as a loving mother and a kind soul who was “full of life and laughter.”

Her death has sparked a massive outpouring of grief and concern, with many expressing disbelief that such a horrifying incident could occur in a residential area in broad daylight.

Arrest Made: Man in Custody

A 28-year-old man has been arrested on suspicion of murder and is currently in police custody. The PSNI has not released his name, but investigators confirmed he is known to the victim. The investigation is being led by Detective Chief Inspector Tom Phillips, who described the circumstances as “deeply distressing.”

DCI Phillips said, “Our thoughts are with Sarah’s family, especially her young children, during what is undoubtedly a time of unimaginable grief. We are working tirelessly to establish the full facts of what happened.”

He called on anyone with relevant information—especially in the local area around Elmfield Walk—to come forward.

A Town in Mourning

The local community in Donaghadee has expressed horror and sorrow in the wake of the tragedy. Floral tributes have been laid outside the house, and neighbours have described Sarah as a “gentle, doting mother.” Community leaders and elected officials have echoed condolences and called for support services for Sarah’s surviving children.

Speaking to local media, one neighbour said, “You just never expect this on your doorstep. We’re all in shock. She was always smiling, always with her wee ones.”

Violence Against Women Still Rising

Sarah’s death has renewed urgent discussions around violence against women and girls in Northern Ireland. In recent years, high-profile cases have put pressure on authorities to introduce stronger safeguards for victims of domestic violence. While PSNI have not confirmed the nature of the relationship between the suspect and Sarah, the tragic context has sparked wider calls for systemic change.

Advocacy groups are again highlighting the need for faster legal protections, education campaigns, and greater funding for women’s shelters and intervention programmes.

What Happens Next

As the PSNI continues its investigation, forensic teams have been combing the scene for evidence. An autopsy is expected to provide further clarity on the precise cause of death. In the meantime, support services are being coordinated for Sarah’s family and children, who are now left without their mother.

Police have reiterated their appeal for information, asking anyone who may have seen or heard anything in the Elmfield Walk area on Saturday to come forward, even anonymously.

A Community Calls for Justice

This heartbreaking case is another painful reminder of the fragility of life and the devastating consequences of violent crime. As Donaghadee and the wider Northern Irish public wait for justice, many are asking how we can prevent this from happening again.

Sarah Montgomery should be remembered not just for how she died, but for who she was—a young woman, a mother, and a life that mattered.
