Summary based on the NamUs case record (MP16289) and 3 other sources
In the summer of 2009, a young man named Lucas Zavala, aged 19, vanished under distressing circumstances near the United States-Mexico border. He was last seen between July 16 and July 19 in the area of Lukeville, Arizona, and Sonoyta, Mexico. Lucas was in the process of crossing into the U.S. when he reportedly became dehydrated and exhausted after walking for eight hours. It was at this point, near a highway, that he was left behind, and tragically, he has not been heard from since.

Lucas, a Hispanic male with black hair and black eyes, stood between 5'3' and 5'7' and weighed between 140 and 160 pounds. He had pierced ears and a distinctive scar on his left knee from a machete cut, described as a line with three dots near it. At the time of his disappearance, he was wearing a black sweatshirt with a white neck, faded blue jeans, and either white sneakers with black stripes or yellow boots. He also wore a black leather belt with a silver buckle that had an image on it and a blue scapular with a depiction of the Virgin Mary. He carried his belongings in a school backpack and had a watch in his pocket.

The specifics of what transpired after Lucas was left by the highway remain unclear, and few details about his case have been made public. His disappearance is classified as a migrant case, highlighting the perilous journey many undertake. The Pima County Office of the Medical Examiner is the investigating agency for his case. The overview of this case is one of a hopeful journey turned into a silent mystery at the border, leaving a family without answers and a young man's fate unknown. The circumstances of his disappearance, succumbing to the harsh elements after a long trek, paint a sorrowful picture of vulnerability.
