Hi, everyone, long time lurker, seldom post, but saw that there are a few of these victims that don't have any posts yet, so I hope you don't mind if I jump in to help you guys.
Here is some information on Monica Candelaria (her last name is spelled wrong in the thread title).

Monica Candelaria’s remains were among those discovered on the mesa. Her mother, Isabel Candelaria, said that shortly after her daughter disappeared in May 2003, she reported to a Bernalillo County sheriff’s detective that a man in her neighborhood named Isaac was overheard saying that Monica Candelaria had been killed and taken to the mesa.
Unconvinced that the police would follow up, Ms. Candelaria said her family spent nearly a month scouring the same land where her daughter’s body would be discovered years later.
A 2003 missing persons report from the Sheriff’s Department confirms Ms. Candelaria’s account. The report said that after Ms. Candelaria informed the department about Isaac, a detective had searched an area near the mesa; the report said that a human jawbone was found there but that it did not match Monica Candelaria’s. The report also shows the matter was turned over to the cold case unit, which followed leads.
“I knew my daughter was buried out there, I just didn’t know if they would ever find her remains,” Ms. Candelaria said. “Maybe some of the girls’ lives would have been saved if they had found my daughter’s body then.”
