Sigurd Beiermann, a 62-year-old vagrant farm worker, was killed on May 24, 1971, in Yuba City, California. His body was found at Sullivan Ranch; investigators say he had been viciously attacked and killed as part of a series of murders targeting vulnerable farm workers in the area.

Authorities linked Beiermann’s death to Juan Corona, a labor contractor accused of luring workers to isolated locations with offers of work. Multiple bodies, including Beiermann’s, were found buried in shallow graves on ranch properties, and a ledger recovered from Corona’s home reportedly listed victims’ names, dates, and amounts of money. Corona was charged with 25 murders, convicted in 1973, and later retried and convicted again in 1982.
