On May 8, 2021, 37-year-old Sara Quintanilla Alacote was shot and killed in her Gwynn Oak, Maryland home during a violent home invasion. The attack formed part of a wider rampage in which Brown also shot and killed another neighbor, Sagar Ghimire, then set his own home on fire. Police responded and shot and killed Brown at the scene.

Reports say investigators found Brown had a history of paranoia and believed he was being surveilled by the government. The killing left the Quintanilla son without his parents, and friends and family set up a GoFundMe to help with funeral costs and support for the surviving child. If anyone knew Sara, her husband Ismael, or the family and can share memories or information, please speak up.
