Melissa takes a first look at the West Mesa Murders in Albuquerque - murders that happened over a long stretch of time but were not discovered until a mass grave was discovered on the mesa outside of town in 2009.  An incredibly frustrating case - especially for the families of the "Lost Girls" who went missing in the years before the discovery of the bones on the mesa - the majority of whom are still missing and who (for all the authorities know) may be buried in other mass graves.  To add to the crushing pain of the families of the victims - one of the key suspects is now deceased - and the other isn't talking.  This one is truly in need of Tip-Sters who can help solve a mystery that deserves resolution.
