A Florida man faces a first-degree murder charge after deputies say he killed his mother, a nurse who tried to get him mental health help.
Florida man Gibson Nash is facing a first-degree murder charge after deputies say he killed his mother, Margaret Chu Dufour, in Polk County following a violent chain of events that began with a crash spree in her blue BMW SUV. The case has drawn attention because Dufour, a 56-year-old nurse, had moved to Florida in an effort to get her son mental health help after repeated arrests and threats against her.
Polk County Sheriff Grady Judd said deputies found Dufour’s body on the floor of her home after Nash was involved in multiple traffic crashes on the morning of July 21. Judd said the crashes began shortly before seven a.m., when Nash allegedly fled the first wreck and then hit several other vehicles. Three people were injured and treated at a hospital. Deputies later found Nash unconscious behind the wheel, covered in blood. He was taken to a hospital, sedated and intubated, after being identified only as an unknown patient at first.
Deputies went to Dufour’s home because the vehicle was registered there. When she did not answer the door, investigators noticed a broken glass plate near the patio door and a shovel near the side of the house. They entered with a key found on the front porch and found Dufour dead inside. The medical examiner determined that she died from blunt force injuries from a beating and strangulation. Judd called it one of the most violent murders he had seen in decades of law enforcement.
The killing followed a troubling history in Tennessee, where Nash and Dufour lived before her move south. In April, Nash was arrested twice for allegedly threatening to kill his mother. In one incident, Dufour called 911 after saying her son had attacked and assaulted her. She told the dispatcher that the only way to calm him was to agree to take him to a smoke shop. Nash was later accused of threatening her with a knife. Later that month, he allegedly threatened her again with a knife after an argument over Xbox use.

Judd said Dufour had recently bonded Nash out of jail and returned to Tennessee before moving to Florida in an attempt to get him more mental health treatment. Family members told investigators that he was bipolar, schizophrenic and possibly autistic. After the Florida crash investigation began, testing found blood on Nash’s clothing matched his mother’s, according to Judd. Investigators also noted bruising on his knuckles and feet, which they said was consistent with kicking, stomping and beating her.
Dufour had recently started work as a nurse on the surgery floor at Bartow Regional Medical Center. Deputies were also familiar with her from a prior call about a disturbance involving movers who she said tried to raise the price of her move. Judd said deputies helped her finish moving items into the home without any fuss. That earlier encounter only sharpened the shock when the same agency later found her dead.
Nash’s lawyer, hired by his father, would not allow law enforcement to interview him, Judd said. Nash is also charged with two third-degree felonies for leaving the scene of a crash involving injury. He is being held without bond in the Polk County jail. The case underscores the danger of untreated violent behavior and the burden it can place on families who try to help loved ones while protecting themselves and their communities.
For American readers, the case is a grim reminder that repeated warning signs can turn deadly when a violent person remains in crisis. The next steps will come through the criminal case in Polk County, where Nash faces murder and crash-related charges and remains behind bars.
