Sean was a kid like most, went to a Catholic school, spent his teens observing and taking interest in the occult, and developed an all-consuming porn addiction. In part one of this two-part series we dive into Sean's upbringing, and what would drive him to commit the first three gruesome murders of eight. 

TW: This episode contains mature themes, rape, bodily mutilation, and graphic material that might be disturbing for listeners under 13.
