SAN ANTONIO - We're getting our first look at the man accused of driving the 18-wheeler that carried the 53 migrants who died during Monday's human smuggling tragedy.

Homero Zamorano, 45, is shown in a surveillance photo, which was taken just before 3 p.m. Monday passing through a customs checkpoint in the city of Encinal.

Mexican authorities showed the photo during a news conference on Wednesday, along with another photo of him in a hospital bed after they say he tried passing himself off as one of the survivors.

Authorities believe Zamorano started his route near Laredo on Monday before making his way through Encinal, Cotulla before abandoning the truck on the Southwest Side of San Antonio. They say a total of 67 migrants were in the back of that sweltering hot trailer.

No charges have been levied against Zamorano at this time, but those could come in the coming days as the investigation continues.
