Police: 16 immigrants locked inside rig at Texas truck stop

EDINBURG, Texas -- Police in Texas acting on a tip found 16 immigrants locked inside a tractor-trailer parked at a gas station about 20 miles from the border with Mexico, less than a month after 10 people died in the back of a hot truck in San Antonio.

Edinburg assistant police chief Oscar Trevino said the immigrants may have been locked inside the 18-wheeler in Edinburg for at least eight hours before being freed by officers late Sunday morning.

He earlier had said there were 17 immigrants locked in the tractor-trailer before correcting the number Monday to 16.

Trevino said none of the people inside the tractor-trailer required medical attention.

He said they were hungry and thirsty and were given food and water at the scene.

Those found locked in the tractor-trailer included eight people from El Salvador, six from Mexico and two from Romania, said Manuel Padilla, U.S. Customs and Border Protection's Border Patrol sector chief for the Rio Grande Valley at Texas' southernmost point.

A man and woman who Trevino said are Cuban nationals were in charge of the rig and have been detained.

U.S. Immigration and Customs Enforcement spokeswoman Nina Pruneda said no one has been charged in connection with the case, but the agency is working with state and local officials and talking to witnesses.

The discovery comes three weeks after 10 people died in a sweltering rig parked at a Walmart in San Antonio.

Immigration officials said survivors estimated 100 people had been packed into the back of the 18-wheeler at one point.

Officials said 39 people were inside when rescuers arrived, and the rest either escaped or hitched rides to their next destination.

Nearly 20 of those rescued from the rig were hospitalized in dire condition, many suffering from extreme dehydration and heatstroke.

The driver of that rig remains in federal custody, charged with illegally transporting immigrants for financial gain, resulting in death.
