On the night of March 29, 2025, 33-year-old Priscilla Danielle Hallihan, a mother of four, was shot and killed in her Port LaBelle, Florida, home. While sitting on the living room couch watching television with her children at about 11:00 p.m., she was struck in the back of the head by a bullet fired from outside the residence. She was taken to Hendry Regional Medical Center and pronounced dead.

The Hendry County Sheriff’s Office arrested 17-year-old Antonio Arenivar the next day. Investigators say Arenivar stood about 15 feet from the home’s window and fired multiple rounds into the living room; he faces homicide and multiple related charges and was transported to a Department of Juvenile Justice facility. A second 17-year-old male has also been arrested; his name has not been released because he is a juvenile. A gun box with a serial number was found at that teenager’s residence, and a handgun with a matching serial number was recovered nearby during a K-9 search. Ballistic testing is pending to determine if that firearm was used in the shooting.

Family and friends described Hallihan as kind and hardworking and devoted to her children.

Did anyone in the Port LaBelle area see or hear anything on the night of March 29 that could help the investigation?
