This article from Brandon's website goes into a bit more detail about how he witnessed his dad kill somebody:
"Hilton grew up in Pacolet, a rural small town in Spartanburg County, South Carolina, about 60 miles southwest of Charlotte. He said he was 2 years old when his dad began beating and molesting him, and when he was 7, his dad shot and killed his mom’s boyfriend in front of him at a McDonald’s. He’s been in prison ever since."
He also owns 6 pet pigs that he keeps in the home, lmao. (Also, I want Breezy broken)
