The Killer Who Prevented Earthquakes: Herbert Mullin

Man Feeds Two Women Into Industrial Shredder in Basement: The double homicide of Adriana Joiosa and Lidia HernándezFreshly painted walls, the smell of bleach, and in the center of the room, an industrial shredder with remnants of flesh and bone. When investigators opened the basement door in Majadahonda, Madrid, they discovered evidence of two women who had vanished without a trace-one five years prior, the other just days before. The forensic contradiction that would haunt this case for years was just beginning.In this investigation, we explore the impossible collision between a severely mentally ill man and the calculated precision of his crimes: forged documents prepared years in advance, a phone moved across multiple Spanish cities to construct a false alibi, internet searches for cremation methods, and the methodical construction of an industrial disposal system. How could a patient with paranoid schizophrenia-a man known to neighbors for screaming about demons and rituals with dead animals-orchestrate two murders with the cold calculation of a psychopath?Victim: Adriana Joiosa and Lidia HernándezDate: April 2015 (Adriana); circa 2010 (Lidia)Location: Majadahonda, Madrid province, SpainStatus: Unsolved (bodies never recovered)- Industrial shredder found in basement contained DNA from both victims mixed together- Bruno's internet history included searches for "cremation," "meat grinder," and "funeral documentation" before the crimes occurred- Adriana's phone continued sending messages and traveling across Spanish cities after she disappeared, with Bruno controlling her digital identity- Bruno submitted forged property transfer documents three years after his aunt vanished, claiming ownership of the building where both victims disappearedAdriana Joiosa, Lidia Hernández, Majadahonda basement murders, 2015, paranoid schizophrenia, industrial shredder, serial killers, investigation, forensic science, unsolved mysteries, homicide, true crime EnglishTo listen to this podcast ad-free and access premium episodes, try our subscription with a 14-day free trial at obomedia.com.© 2026 OBOMEDIA.
