Serial murder investigations whose offender was never officially identified, including the 1888 Whitechapel murders in London and the 1968 to 1969 murders in Northern California attributed to the Zodiac. A case belongs here when its cited source states that the identity of the offender remains officially unresolved. Entries are recorded as genuinely open questions, and no candidate suspect is named as the offender, so the group describes the state of the investigation rather than any theory of who was responsible.
