Summary based on the NamUs case record (MP16657) and 1 other source
In the vast and often unforgiving landscape of the Arizona desert, the story of Maria Mejia Lastor's disappearance began on October 1, 2010. At 31 years old, Maria, a Hispanic female with dark brown eyes and short black hair that did not reach her shoulders, was last seen in the area of Altar, Arizona. She stood between 57 and 58 inches tall and weighed between 140 and 160 pounds. A small but distinct birthmark, the size of a nickel, on her right leg served as a unique identifying feature. On the day she vanished, she was reportedly wearing a brown blouse, stone-washed jeans, and black tennis shoes. It is a journey that many undertake with hope, but for Maria, it marked the last time she was in contact with those who knew her.

The circumstances surrounding Maria's disappearance are sparse, pieced together from the little information available. It is understood that she was in the process of crossing the border and had been walking for a day, approximately 10 hours, before she went missing. She was carrying a black backpack containing personal items such as Pedialyte, Gatorade, lemon garlic, Maria's cookies, and face cream, essentials for a difficult journey. The official report of her disappearance was not filed until October 20, 2010, with the Pima County Office of the Medical Examiner in Tucson, Arizona, taking charge of the investigation. Despite the passage of time, details beyond these initial accounts remain limited to the public.

The case of Maria Mejia Lastor is a poignant reminder of the perils faced by many who traverse the borderlands. With no updates on her whereabouts for many years, her case has grown cold, leaving her family and loved ones in a state of prolonged uncertainty. The investigation, managed by the Pima County Office of the Medical Examiner under case number FSC MPR 1219, remains open. The narrative of her last known moments paints a picture of a woman undertaking an arduous trek, equipped with simple provisions, who ultimately vanished into the harsh terrain. Her story is one of many that highlight the human element of migration and the profound sense of loss that accompanies an unresolved disappearance. The lack of available information for public view has left many questions unanswered, and the search for Maria continues to be a quiet but persistent effort.
