In the basement of Preston Castle, the most discussed event is the 1950 murder of housekeeper Anna Corbin, whose killing and its aftermath turned that part of the building into the focus of many ghost stories and true-crime interest.

Key incident in the basement

  • In February 1950, longtime housekeeper Anna Corbin was found dead in a basement storeroom at Preston Castle (the former Preston School of Industry) in Ione, California.
  • She had been beaten and strangled, and her body was partially concealed with rugs in a corner of the room, which reinforced the sense of a deliberate, brutal crime.

What is known about the case

  • A young inmate from the school was charged with her murder and faced three separate trials, but each trial ended without a conviction, so the case remains officially unsolved.
  • Historical sources and later write-ups emphasize that the lack of a clear resolution has fueled speculation and conflicting theories about who was responsible and what exactly happened in the moments before her death.

Why the basement is talked about so much

  • Because Corbin’s body was discovered in the basement area, many later accounts, paranormal tours, and TV shows single out that part of the building as especially significant or “haunted.”
  • Stories commonly claim that her spirit lingers near the basement, and her murder is often treated as the central tragedy in Preston Castle’s haunted reputation in modern coverage and ghost-tour narratives.

Other basement-related history

  • Separate from Corbin’s case, at least one earlier death at the school involved boys being locked in the basement after a fight; one boy, Leland Price, suffered a skull fracture on the concrete floor and later died, which also contributes to the basement’s dark history.
  • Over time, these incidents have been woven together in online forums, documentaries, and horror media, blending documented history with rumors and dramatized retellings tied to “what happened in the basement of Preston Castle.”

TL;DR: The basement of Preston Castle is infamous mainly because housekeeper Anna Corbin was found there in 1950, beaten and strangled, with no one ever successfully convicted, turning that space into a focal point for both true-crime curiosity and haunted-castle legends.
