Summary based on the NamUs case record (MP89690)
Alan Santos Mejia, a 25-year-old man, went missing on August 27, 2021, near Falfurrias, Texas. He had embarked on a journey through the treacherous terrain of South Texas while crossing the U.S.-Mexico border, a common route for migrants attempting to bypass checkpoints. His family last heard from him around that date, and since then, there has been no further communication. Santos Mejia was traveling with a group of migrants, and it is believed that he may have become separated from the group or succumbed to the harsh environmental conditions often faced in that region, such as extreme heat and dehydration.

At the time of his disappearance, Mejia was wearing black Nike tennis shoes with red logos, a black shirt, and blue jeans with red patches. He also carried a gray Samsung cellphone and wore a black necklace bearing an image of the Virgin of Guadalupe. Despite efforts by family members and organizations involved in searching for missing migrants, including outreach by local consulates and law enforcement agencies, his whereabouts remain unknown.

The Falfurrias area, known for its dangerous conditions, has seen many disappearances as migrants attempt to avoid detection. Water stations have been set up in an effort to aid those in peril, but the challenges remain vast, with many cases like Mejia's unresolved. His family and local authorities continue to search for information, hoping to bring closure to this painful situation.
