Melisa Sarai Romero Piedrasanta, a 23-year-old Guatemalan national, went missing on June 11, 2018, after crossing the U.S.-Mexico border with a group of migrants. She crossed near Nuevo Laredo, Tamaulipas, Mexico, and was reportedly last seen in Kingsville, Texas, after being abandoned by her group.

At the time she disappeared Melisa was wearing blue canvas pants, a black long-sleeve shirt, and black tennis shoes, and had a distinguishing mole on the left side of her mouth. Little is known about the exact circumstances of her disappearance; her case is one of many involving missing migrants in the Falfurrias area and Brooks County, places noted for difficult terrain and high migrant mortality from heat and dehydration.

Search efforts have not located Melisa and the case remains unsolved. If anyone knew Melisa, saw a group coming through the Kingsville or Falfurrias area on or after June 11, 2018, or has information about her whereabouts, please share what can help investigators or organizations working on missing migrant cases.
