On February 6, 2026, Youngsville Police Department officers responded to a report of a stolen white SUV from a residence in the 200 block of Fourth Street in Youngsville, Louisiana. The call came in around 9:30 a.m., prompting a swift search for the vehicle in the quiet residential neighborhood known for its family-oriented atmosphere in the growing Lafayette Parish suburb.
Patrol units quickly located the missing SUV and initiated a pursuit when the driver refused to stop. The chase was brief but intense, ending with the apprehension of the suspect without further incident. Officers took 20-year-old Dylan Green into custody, initially facing charges related to the vehicle theft and evasion.
Shortly after the arrest, authorities received a separate welfare check call from the same address on Fourth Street regarding an unresponsive woman inside the home. Responding officers entered the residence and discovered 70-year-old Thelma Thibeaux deceased. The scene immediately shifted to a homicide investigation as evidence pointed to foul play.
Investigators soon connected Dylan Green to the victim, identifying him as Thibeaux’s grandson. The sequence of events suggested he had allegedly killed her before fleeing in her SUV. Forensic teams processed the home for evidence while detectives interviewed potential witnesses in the surrounding area.
Green was booked into the Lafayette Parish Correctional Center on charges including first-degree murder, aggravated flight from an officer, and unauthorized use of a motor vehicle. Prosecutors view the case as deliberate, with the homicide classification underscoring the severity of the allegations against the young suspect.
The Youngsville community has expressed profound shock and grief over the loss of Thelma Thibeaux, remembered as a beloved grandmother. Residents struggle to reconcile the familial tragedy in their peaceful town as the investigation continues.
