Maria Amaya Corado was a 38-year-old Hispanic/Latina woman when she was last seen on May 20, 2008, in the Douglas, Arizona, area near the United States–Mexico border. The circumstances publicly associated with her disappearance indicate that Maria had crossed into the Douglas area while traveling with a group. At some point during the journey, she became physically unable to continue walking.
The others reportedly left her behind somewhere near an area described as Streets 70 and 80, in the vicinity of ranches outside Douglas. It was a vulnerable situation: Maria was separated from the people with whom she had been traveling and was apparently unable to keep moving under her own strength. According to the account preserved in public missing-person records, someone later returned to the location to look for her, but Maria was no longer there. That unsuccessful return is the last clearly described development in the known sequence of events surrounding her disappearance.
What happened to Maria after she was left near the ranches has remained unclear in the publicly available account. The information does not explain why she had become unable to walk, how much time passed before someone went back for her, whether she had attempted to move to another location, or whether she encountered another person after the group departed. There is likewise no publicly described eyewitness account establishing where she went once she was alone. Those missing details leave an especially painful gap in the story: the known circumstances place Maria in a specific general area and describe an attempt to return for her, yet by then she had disappeared from the place where she had last been left. Public case information identifies the location simply as Douglas, Arizona, while the more detailed circumstances place the last-known area near ranch properties around Streets 70 and 80. Her disappearance is recorded under NamUs missing-person number MP17186.
Descriptions circulated in public missing-person listings identify Maria as female and Hispanic/Latina, with brown hair and brown eyes. She was approximately 5 feet 1 inch to 5 feet 3 inches tall and was reported in the range of approximately 150 to 170 pounds. One public case summary gives the more specific baseline of 61 inches in height and 150 pounds, while broader missing-person listings present the expanded height and weight ranges. These characteristics remain important because there is so little publicly documented information about the moments after Maria vanished. Unlike cases in which a vehicle, destination, confirmed sighting, or later communication provides investigators with another point on a timeline, the public narrative of Maria's case ends at the place where she was left and the discovery that she was gone when someone returned. Her identifying information therefore remains one of the principal means by which her case can be distinguished from the many other missing-person cases associated with southern Arizona.
Years after May 20, 2008, public missing-person databases have continued to preserve Maria's name, identifying details, disappearance location, and NamUs case number. The available record is notably sparse, and it does not publicly reconstruct Maria's movements beyond the moment she could no longer continue with the group. There is no documented later sighting in the sources describing her case, no publicly identified destination she was known to have reached, and no subsequent event described that explains why she was absent when the person searching for her returned. What remains is a troubling and deeply human sequence of events: a 38-year-old woman became exhausted or otherwise unable to continue walking after reaching the Douglas area, was left near ranches while the rest of the group moved on, and was missing when someone went back for her. Maria Amaya Corado's case, recorded as NamUs MP17186, is therefore defined by a narrow but significant window of uncertainty—the time between her being left behind and the return of the person who tried to find her—and by the enduring unanswered question of where she went from that isolated last-known location. In overview, Maria was last seen in Douglas, Arizona, on May 20, 2008, at age 38; she had been traveling with a group, became unable to continue, was left near ranches around Streets 70 and 80, and could not be located when someone subsequently returned to search for her, leaving the circumstances of what happened afterward unresolved in the publicly available record.Last Seen: May 20, 2008
