A horrifying domestic violence incident unfolded in Farmingville, New York, on the night of Thursday, February 12, 2026, leaving one woman dead and two others injured. Suffolk County Police responded to a 911 call reporting a disturbance at 144 Granny Road at approximately 8:15 p.m. Upon arrival, officers discovered a chaotic and bloody scene inside the residence, where multiple victims had sustained stab wounds.
The victim, 46-year-old Adriana Barbosa, was found critically injured alongside her estranged husband, 57-year-old Marcos Marques-Leal. A teenage relative, who was also present in the home at the time of the attack, had suffered stab wounds as well. Emergency responders transported all three individuals to Stony Brook University Hospital. Tragically, Barbosa was pronounced dead shortly after arrival due to the severity of her injuries.
According to investigators, the incident is being treated as a domestic violence case. Marques-Leal allegedly stabbed Barbosa during a confrontation and then turned the knife on himself in an apparent suicide attempt. The teenage relative, whose identity has not been released, sustained non-life-threatening injuries and is expected to recover. The teen’s presence during the attack has added a deeply traumatic layer to an already devastating event.
Authorities have since charged Marcos Marques-Leal with second-degree murder, criminal contempt, and endangering the welfare of a child. He remains hospitalized under police custody due to the serious nature of his self-inflicted wounds. Investigators have not disclosed the motive behind the attack, but court records indicate a history of domestic issues between the couple, including a prior order of protection that Marques-Leal allegedly violated.
The residence on Granny Road, a quiet suburban street in Farmingville, has become the focus of a community in mourning. Neighbors expressed shock and sorrow, describing Barbosa as a devoted mother and kind neighbor. The incident has reignited conversations about the dangers of domestic violence and the importance of early intervention and protective measures for at-risk individuals.
As the investigation continues, Suffolk County officials are urging anyone experiencing domestic abuse to seek help and utilize available resources. The tragic death of Adriana Barbosa underscores the urgent need for community awareness, support systems, and legal protections to prevent similar tragedies in the future.
