An Arizona woman is facing smuggling charges after three illegal immigrants were found crammed into the trunk of her car.

Border Patrol Agents from the Sonoita Station in Tuscon stopped a 1998 Toyota Camry to check the immigration status of the driver, who appeared to be traveling alone.

However, the men, believed to be from Mexico, were found squashed together in the back of the vehicle on Thursday, reported Tucson News Now.

A 56-year-old woman from South Tucson was arrested for smuggling and agents seized the vehicle. The three men will be charged with immigration violations.

The U.S. Customs and Border Protection said in a statement that smuggling the illegal aliens in the such a fashion was extremely dangerous for their health.

The statement read: 'Further inspection of the Camry revealed there was no emergency trunk release.

'Even during monsoon season, Arizona's summer temperatures can climb dramatically when the sun comes out. Adding the possibilities of being crushed in a rear-end collision, or being poisoned by carbon monoxide, riding in the trunk of a vehicle could be equivalent to a death sentence.'

In June, the Tucson Sector Border Patrol implemented a new policy to prosecute human smugglers on both sides of the border, after a review of its program with the Mexican government.

'The program enables the prosecution of Mexican human smugglers, through Mexican courts, using information obtained via interviews conducted by Border Patrol agents while in U.S. custody,' said CBP in a news release.

In fiscal year 2016, Tucson Sector Border Patrol submitted 143 human smugglers to the government of Mexico to see if they could be up for prosecution in their court system.

Meanwhile in Texas, a man will be charged in federal court Monday following his arrest in the deaths of nine people whose 'very hot' bodies were found in a sweltering tractor-trailer in a San Antonio Walmart parking lot alongside nearly 20 others who were still alive but in dire condition.
