Federal investigators said they have three smuggling suspects in custody Tuesday and at least 50 migrants are dead of heat exposure after being trapped in the back of a truck in the hot Texas sun.
The truck was found on a country road in San Antonio. The fatalities mark one of the worst tragedies in border history and ignited a search for answers to the growing migrant death toll under President Biden.
The president blamed smugglers, though his critics — including Texas Gov. Greg Abbott — said it was Mr. Biden who lured the migrants to make the journey through his relaxed border policies.
