Kassi Henderson, 33, of Marianna, Florida, was killed on February 11, 2017, in a double homicide at a mobile home in the Rocky Creek community. The other victim was 61-year-old Mary Reed. Jackson County deputies say the killings followed a domestic argument that escalated into violence.

Seventy-five-year-old William Hawk of Fountain was identified as the suspect. He had a relationship with Reed and was listed as her emergency contact. Deputies received a frantic call that someone at the residence had a gun; after initially finding nothing, they later discovered Henderson and Reed dead in the living room following a phone conversation with Hawk. Hawk left the scene, returned about 2 a.m., admitted to the shootings to investigators, and was shot by a deputy after failing to drop a weapon. He was treated at an Alabama hospital and taken into custody; he faces murder and aggravated assault on an officer charges. The deputy was placed on administrative leave while the Florida Department of Law Enforcement investigated.

Henderson, a Phoenix native visiting Reed for the winter, had been planning to return to Arizona in March and was remembered by her father as strong and loving. The motive was reported as related to a domestic dispute; the investigation was ongoing. Anyone with information about Kassi Henderson or the events that night is asked to come forward.
