Affluent enclave rocked by brutal slaying — suspect’s Facebook posts appeared to target victim: report

Published on March 25, 2026

A tranquil suburb in Lafayette, California, was shaken last week by a brutal slaying that has left residents in shock. David Prince, a local man, has been charged with murder following the fatal attack, during which he allegedly used a hatchet to kill a resident whose identity has been confirmed as 28-year-old Barbara Miller.

Details surrounding the incident have emerged, including troubling posts made Facebook prior to the murder. Reports indicate that these cryptic messages may have specifically referenced Miller, raising concerns about the potential motivations behind the attack. Friends and family members of Miller expressed devastation over the loss, describing her as a beloved member of the community who was actively involved in various local initiatives.

The attack occurred late Saturday night in a seemingly peaceful neighborhood, where incidents of violence are exceedingly rare. Witnesses reported hearing loud noises and screams before authorities arrived on the scene, finding Miller with life-threatening injuries. Paramedics attempted to revive her, but she was pronounced dead shortly after.

Prince was taken into custody without incident at the scene and has since been held at the Contra Costa County Jail. Legal experts suggest that the evidence against him may include both physical proof from the crime scene and the troubling online posts. The posts, which have since garnered attention, hinted at a deep-seated anger and could potentially be used to establish a motive in the prosecution’s case.

Community members have expressed their outrage and confusion over the incident, with many gathering to honor Miller’s memory. A candlelight vigil is planned for this weekend to pay tribute to her life and raise awareness about violence within communities that are often perceived as safe.

As the investigation continues, authorities are urging anyone with information about the case to come forward. The court proceedings for David Prince are set to begin next week, and the community remains in mourning, grappling with the chilling reality that such a violent act could occur in their midst.
