Authorities initially served a search warrant at the house after someone called police Thursday night to report a loved one was being held there.

Adan Lalravega said he was told the $5,500 he was being charged to be smuggled into the United States would include an air-conditioned truck ride.

A passenger of the broiling hot tractor-trailer found packed with immigrants told authorities that they took turns breathing through a hole and pounding on the walls to try to get the driver's attention.
