Authorities said Holliman was living with Dexter and Kirby in their home, and that the son attended church with Holliman.
Holliman reportedly got into an argument with the Taylor's and drenched them with a flammable liquid and set them on fire with a barbecue-style lighter.
Dexter died, but his father, who was severely burned, survived the fire.
It's not known why Holliman attacked the 67-year-old father and his son.
