Michelle Gina Valdez was 22 and pregnant when she disappeared in Albuquerque on September 22, 2004. She later became one of the victims recovered from a West Mesa burial site after a walker found a bone in February 2009; excavators uncovered the skeletal remains of 11 women and an unborn child, and an autopsy confirmed Valdez was a homicide victim though a specific cause of death could not be determined.

Investigators linked the West Mesa discoveries to a suspected serial killer; many of the victims, including Valdez, had histories involving drugs and sex work. No arrest has been announced in Michelle’s murder. Two men, Lorenzo Montoya and Joseph Blea, have been identified as persons of interest in the broader investigation, but authorities say there is not enough evidence to tie either man conclusively to the slayings.

Did anyone who knew Michelle or saw her in Albuquerque in 2004 notice anything that might help finally close this case?
