Summary based on the NamUs case record (MP53383) and 1 other source
Sergio Ortiz Perez, a 20-year-old Guatemalan national, was last seen on December 1, 2017, near McAllen, Texas. He was attempting to enter the United States illegally, possibly crossing the Rio Grande from Mexico into the U.S. through Hidalgo County. Ortiz Perez was part of a group of migrants and has not been heard from since that day. Few details are available about what happened to him during the crossing, and it is feared that he may have encountered trouble during his attempt to enter the U.S.

At the time of his disappearance, Ortiz Perez was described as standing 5'2" to 5'3" and weighing around 130 to 140 pounds, with black hair and brown eyes. He also had a noticeable scar near his ear. The Hidalgo County Sheriff's Office is investigating his case, though updates have been sparse since his initial disappearance.

Authorities continue to urge anyone with information regarding his whereabouts or what may have occurred to come forward to assist in resolving his case.
