Meanwhile, the FBI is investigating the deaths of four unidentified people, including one toddler and two infants, who were found by Border Patrol agents along the Rio Grande in Texas’s Rio Grande Valley near the U.S.-Mexico border. The bodies were discovered Sunday, but their condition indicated they could have died days before that. Investigators say the three young children and a woman in her early twenties appear to be migrants who died from dehydration and heat exposure, though official autopsy results have yet to be released.
Separately, the bodies of a Salvadoran migrant and his 2-year-old daughter were found, also on Sunday, on the Mexican side of the southern border near Brownsville, Texas, according to Mexican and Salvadoran news reports.
