Driver of Texas migrant death truck ‘did not know air conditioning was broken’

Homero Zamorano Jr is in custody with three other suspects in case of deaths of at least 53 migrants near San Antonio

The driver of the trailer truck in which at least 53 migrants died before being abandoned in San Antonio this week did not realize the vehicle's air conditioning system was broken, federal court documents said.

The detail was contained in records explaining why investigators arrested a man with whom the driver exchanged text messages, in what is believed to be the deadliest migrant smuggling episode on the US-Mexico border.
