[Value of cyanosis and petechiae in strangulation and concurrent severe anemia (author's transl)]

Cyanosis, petechiae, and hemorrhages into the soft tissues and muscles of the neck may be absent after strangulation (throttling) during life, if severe bleeding has happened before. If in severe anemia signs directly or indirectly caused by strangulation have developed, it may be suggested that strangulation occurred during life and persisted for some time.
