Summary based on the NamUs case record (MP51049) and 1 other source
Jonnathan Jose Sanchez Andrade, a 20-year-old from Ecuador, went missing on December 4, 2017, near McAllen, Texas. He was reportedly crossing the U.S. border illegally as part of a group of migrants. According to other group members, after traveling for four hours outside of Houston, Texas, Jonnathan complained that he could no longer continue walking. The group, believing that Border Patrol would eventually find him, left him by the roadside. However, Jonnathan was never heard from again.

Jonnathan has several distinguishing features, including a scar on his left eyebrow, a mole below his left eye, and a tattoo of Chinese characters on his wrist. At the time of his disappearance, he also had a black earring expander in his left ear. Despite efforts from his family and authorities, no further information has surfaced, and the case remains unsolved.
