Desperate families of migrants from Mexico and Central America frantically sought word of their loved ones as authorities began the grim task Tuesday of identifying 51 people who died after being abandoned in a tractor-trailer without air conditioning in the sweltering Texas heat.
Victims have been found with no identification documents at all and in one case a stolen ID. Remote villages lack phone service to reach family members and determine the whereabouts of missing migrants. Fingerprint data has to be shared and matched by different governments.
