[Part 1 of 4] *** Content warning: child victims *** The quiet suburban life of Wichita, Kansas, was shattered in 1974 when four members of the Otero family, Joe, Julie and their two youngest children, Josie and Joey, were found brutally murdered in their home. Nine months later, a letter was discovered inside a public library book that contained detailed, accurate, insider-knowledge about the crime. Worse still, the writer claimed responsibility for the murders and threatened to kill again.
