VAN ALSTYNE, TX – A standoff in Van Alstyne involving a suspected Carrollton murderer ended with the suspect dead from a self-inflicted gunshot wound on October 21, 2025.
On October 20, Carrollton Police were dispatched to a medical emergency in the 4600 block of North Josey Lane, where 24-year-old Briana Casto was found deceased from an apparent gunshot wound. Detectives quickly identified her boyfriend, 24-year-old Jomaar Lee Davis, as the primary suspect and obtained a warrant for his arrest.
The following day, information obtained by the Celina Police Department indicated that Davis was in the Van Alstyne area. At approximately 3:30 am, officers from the Van Alstyne and Anna Police Departments responded and located Casto’s vehicle, which Davis was occupying. A standoff ensued.
