The blood-drawn pentagram found near the bodies is likely the work of the ghost, possibly as part of a ritual or to create a sinister atmosphere befitting his evil nature. Some interpretations suggest the boy may have been involved in occult activities, or the pentagram simply represents the dark supernatural power that binds his spirit to the house.
