Sawt Falasteen - Toll in migrant trailer tragedy rises to 53

Eleven others remained under treatment in local hospitals, Immigration and Customs Enforcement said, without specifying their conditions.

That was up from Tuesday, when local officials put the number of dead at 51, including 39 men and 12 women.

According to Francisco Garduno, head of Mexico's National Migration Institute, the dead included 27 Mexicans, 14 Hondurans, seven Guatemalans, and two Salvadorans.

The nationalities of the other three were not yet revealed.

San Antonio police were first alerted to the trailer by an emergency call at about 5:50 pm local time (2250 GMT) on Monday.

A worker near an isolated road in San Antonio heard a cry for help, went to investigate the trailer and found a number or corpses inside.

Federal law enforcement agents on Tuesday arrested two men at the address linked to the tractor-trailer's registration, court documents showed.

Juan Francisco D’Luna-Bilbao and Juan Claudio D’Luna-Mendez, both Mexican nationals whose US tourist visas had expired, were illegally in possession of multiple firearms, the documents alleged.

A third person, suspected of being the driver of the tractor-trailer, was arrested nearby while "very high on meth," reported the local daily San Antonio Express-News, citing a law enforcement officer.
