A decomposed body found in Texas near the border with Mexico earlier this month has been identified as an 11-year-old undocumented immigrant from Guatemala , the Hidalgo County Sheriff 's Office said Monday . Gilberto Francisco Ramos Juarez was found dead in the brush near La Joya on June 15 , authorities said . An autopsy showed no signs of trauma , said J.P. Rodriguez , a spokesman for the sheriff 's office . The boy was found wearing pants , a belt and boots . `` The pathologist believes because of the way that we found the body , it had no shirt ... that 's a sign of heatstroke , '' Sheriff Eddie Guerra said , adding that a toxicology report is pending . Rodriguez said it appears the boy strayed from a group that included some relatives , possibly after crossing the Rio Grande . Guerra theorized the boy was `` wandering aimlessly '' through the area . Authorities were able to identify the boy after they discovered a phone number on his belt buckle . A series of calls led them to the boy 's father , who described the clothes the boy was wearing . The boy 's brother told authorities that Ramos was last seen with an uncle , who had been detained by Border Patrol agents , according to a news release from the sheriff 's office . CNN affiliate KRGV reported that the sheriff is still investigating how the boy ended up dead in the bushes and who brought him into the United States . The U.S. government has struggled to process and accommodate an influx of illegal human traffic but specifically a spike in immigrant children . The government does n't have enough beds , food or sanitary facilities . U.S. authorities estimate between 60,000 to 80,000 children without parents will cross the border this year in what the White House is calling an `` immediate humanitarian crisis . '' Earlier in June , the White House announced a plan to spend millions in a government-wide response by sending aid to governments in Guatemala , Honduras and El Salvador to help with crime and violence prevention .
Sheriff believes boy became lost , probably died of heat stroke . The sheriff says the boy's mother called 911 and reported her son missing at about 11 a.m. on Monday. Police tracked down family through phone number on belt buckle . U.S. has been dealing with increasing numbers of children crossing border .
