Rising train fatalities among migrants in Texas border area.

A second incident of train deaths occurred in Texas, this time in Eagle Pass, where one person was found dead and three others were injured. The discovery follows Friday's separate report of 15 suspected migrants on board a freight train about 70 miles northeast of Saturday's incident. The exact cause of the medical emergencies on both trains, which use the same line that runs from the U.S.-Mexico border to San Antonio and beyond, was unavailable. It wasn't immediately clear whether the freight train discoveries are coincidental or representative of a new wave of migration among those desperate to reach the U.S. from points south.
