Tragic discovery of trapped migrants in Texas train car.

A 911 call from a boxcar parked at a Union Pacific rail yard led authorities to discover 12 migrants trapped inside, one of whom was pronounced dead at the scene and three others hospitalized. The incident occurred near Eagle Pass, Texas, on the U.S.-Mexico border and is being investigated as a case of human smuggling. The discovery came a day after 17 migrants were found locked in a "suffocating" train freight container in Uvalde County, including two who perished.
