HIDALGO, TX - MARCH 14: A U.S. Border Patrol agent stops traffic as immigrants are deported across an international bridge into Mexico on March 14, 2017 from Hidalgo, Texas. The Trump administration has ordered an increase in deportations, part of the larger strategy to get tough on illegal immigration and strengthen border security.

(FILES) In this file photo taken on November 1, 2017 US Border Patrol officer Tekae Michael stands near prototypes of US President Donald Trump's proposed border wall in San Diego, California. A border patrol agent whose mysterious death prompted President Donald Trump to renew his call for a wall along the US-Mexico border appears to have died as the result of an accident, according to an FBI probe. An FBI investigation into the November 2017 death of agent Rogelio Martinez has not found any evidence of foul play."To date none of the more than 650 interviews completed, locations searched, or evidence collected and analyzed have produced evidence that would support the existence of a scuffle, altercation, or attack," the FBI said in a statement on February 7, 2018. / AFP PHOTO / FREDERIC J.

Here, Ortega drops off the medicine at an AIDS outreach center in San Diego, which will then be transported across the border to Bi?National AIDS Advocacy Project and Casa Hogar Las Memorias in Tijuana.

Earlier exactly the opposite conditions prevailed, with scores of Mexicans struggling to break thru a tight cordon of Mexican police and soldiers to reach the American side of the boundary.

DALLAS (AP) — Federal prosecutors charged five people Tuesday in a scheme to smuggle immigrants illegally after an SUV driven by one of them crashed in Texas while fleeing Border Patrol agents, killing five passengers.

The crash happened Sunday after Border Patrol became suspicious of three vehicles traveling in a convoy between El Indio and Carrizo Springs, Texas, according to a statement from the U.S. Attorney's Office for the western district of Texas. When agents tried to make "immigration inspections," two of the three vehicles — a 2007 Suburban and a 2008 Tahoe — led authorities on a high speed chase.

The Suburban, carrying 14 people and traveling more than 100 mph (161 kph), lost control and overturned on Texas Highway 85 as it was entering Big Wells, a town about 100 miles southwest of San Antonio. Most of the occupants were ejected. Four passengers died at the scene and another died enroute to the hospital. The names of the victims have not been released.

The man driving that SUV, 20-year-old Jorge Luis Monsivais Jr., was among those charged, along with the driver of the vehicle that did not take off when agents approached, 55-year-old Marcial Gomez Santana. Two of the others charged are Santana's children. The fifth person charged was a passenger in the convoy.

They are charged with transporting and conspiracy to transport and harbor "illegal aliens resulting in serious bodily injury and death."

ALSO

The driver of the other vehicle that tried to elude agents, a 17-year-old unidentified U.S. citizen, was detained and is in the custody of Dimmit County authorities. The teenager has not been charged by federal authorities.

Prosecutors said Tuesday that nearly two dozen people believed to be in the country illegally were involved in the smuggling scheme.

The incident comes amid heightened tensions over the treatment of immigrants at the southern U.S. border. The Trump administration has announced a "zero tolerance" policy toward illegal immigration that includes separation of children from their families in some cases. The policy has sparked outrage from Democrats and some Republicans.

Daryl Fields, a spokesman for the U.S. Attorney's Office, said in an email that four of those charged made their initial court appearances on Tuesday in Del Rio, Texas, and Monsivais is expected to have an initial appearance Wednesday morning. It was not immediately clear if they have defense attorneys.
