Amanda Bragg, 30, a white female, was killed on the night of November 4, 2015, inside a first-floor apartment at 35 Belgrade Road in Oakland, Maine. Responding to multiple 911 calls around 8 p.m., police found three victims inside—Bragg; her boyfriend, 29-year-old Michael Muzerolle; and Bragg's sister, 28-year-old Amy Derosby. Outside in the driveway, officers discovered the body of the shooter, identified as 42-year-old Herman Derico, who died of a self-inflicted gunshot wound.
A 3-year-old girl who had been in the apartment during the attack was found unharmed and was placed with family.
Investigators said Derico used a 9mm handgun to kill Bragg, Muzerolle, and Derosby before turning the weapon on himself. In the minutes before she succumbed to her injuries, Derosby managed to call 911 and provide critical information that helped first responders secure the scene. Authorities from multiple agencies—including the Maine State Police and a tactical team—converged on the residence, but officials emphasized early on that they were still working to determine a motive.
In the aftermath, the town mourned the three victims. Community members held a candlelight vigil five days later, and their names were later added to a statewide memorial for Maine homicide victims. Local remembrances and obituaries described Bragg's life and roots in central Maine, underscoring the shock that rippled through the area after the crime.
No arrests were made; the suspected gunman was dead at the scene, and investigators treated the case as a triple homicide followed by the shooter's suicide. Officials said they had no immediate explanation for the violence, and public updates in the days that followed did not identify a clear motive.
