Doreen Marquez was 24 when she vanished from Albuquerque on October 10, 2003. Her exact date of death is unknown; investigators believe she was killed sometime between 2003 and 2005 and buried on a remote stretch of the West Mesa near 118th Street SW, where development had not yet reached.

A woman walking her dog found bone fragments on February 2, 2009, triggering recovery of a sprawling grave site. Over the following weeks authorities recovered remains of eleven females and one unborn child; Doreen Marquez was identified in April 2009. The burial location and condition of the remains left little forensic trace, so identification and the investigation have depended on timelines, missing‑person lists and patterns among women who had vanished from Albuquerque’s streets.

Police have said an unknown person killed and buried Doreen; no arrests have been made in the West Mesa murders. Investigators examined several persons of interest over the years, including Lorenzo Montoya and Joseph Blea, and other names surfaced in media coverage, but no prosecutable link to the mesa killings was established.

If anyone knew Doreen, saw her in 2003–2004, or has information about activity on the West Mesa, please share what is known with investigators.
