Summary

Ireland’s Vanishing Triangle is an area around Dublin from where multiple women have mysteriously vanished in the 1990s. Most of the cases have the same characteristics and remain unsolved. Were they taken by a serial killer? Irish Police created Operation Trace in 1998 to actively solve the disappearances but have not been able to do so. A €10,000 reward has been offered for information resulting in the recovery of a body, as it is presumed that the victims are no longer alive.
