Summary based on the NamUs case record (MP3906) and 3 other sources
In the fall of 1990, in Phoenix, Arizona, a young woman named Maria De Los Angeles Martinez was seeking a babysitting job to earn some extra money. On October 12, the 18-year-old advertised her services on a local radio station. A man responded to her advertisement, and the following morning, on October 13, 1990, at approximately 10:00 a.m., he arrived at her family's home to pick her up. Maria, described as a Hispanic female with black hair, brown eyes, and a noticeable four-inch scar on her right forearm, left with the unidentified man, dressed in a green and black jumpsuit. Her family would never see her again.

A short time after leaving her residence, Maria made a frantic phone call to her parents. In the brief and harrowing conversation, she asked them to come and pick her up. Tragically, before she could provide her location or any details about the man she was with, the telephone line was disconnected. The identity of the man who responded to the babysitting ad and picked her up remains unknown. The abrupt and mysterious end to the phone call was the last contact anyone had with Maria De Los Angeles Martinez.

The investigation into Maria's disappearance has spanned decades, yet tangible answers remain elusive. She is also known by several aliases, including Maria Pereyra De Los Angeles, Maria Pereyra, and Maria Martinez-Pereyra. Physical characteristics noted at the time of her disappearance, besides the scar on her arm, included a mole on her nose and pierced ears. The Phoenix Police Department has been the primary investigating agency for her case. Despite the passage of time, Maria's case remains an active and deeply concerning mystery, a poignant example of the vulnerability of a young person simply trying to find work. The circumstances of her last known moments, a distressing phone call cut short, paint a chilling picture of her final, fearful experience.
