The fire happened at the home of Griffis' father on Ridgecrest Drive, according to deputies. The York County Fire Marshal's Office investigated and found the fire to have been "intentionally set," police said.
Detectives with the sheriff's office determined that Griffis went to the home without permission and set the fire, police said. Griffis was taken into custody Saturday by Rock Hill Police Department officers then charged by York County deputies, police reports show.
