California crash kills 13 of 25 people crammed into SUV

An SUV packed with 25 people pulled in front of an oncoming tractor-trailer on a two-lane highway cutting through farmland near the US-Mexico border on early Tuesday, killing 13 and leaving bodies strewn across the roadway. Most of the dead were Mexicans, a Mexican official said.

When police arrived, some of the passengers were trying to crawl out of the crumpled 1997 Ford Expedition while others were wandering around the fields. The rig's front end was pushed into the SUV's left side and two empty trailers were jackknifed behind it.

Twelve people were found dead when first responders reached the highway, which winds through fields in the agricultural southeastern corner of California about 125 miles east of San Diego. Another person died at a hospital, California Highway Patrol Chief Omar Watson said.

It was a pretty chaotic scene, said Watson, who also described it as a very sad situation. Roberto Velasco, director of North American affairs for Mexico's Foreign Relations Department, confirmed Tuesday on his Twitter account that at least 10 of those killed have been identified as Mexicans. No identities have been released.

The cause of the collision was unclear, authorities said, and it also was not immediately known why so many people were crammed into a vehicle built to hold eight people safely.

Watson said the SUV only had front seats the middle and back seats had been removed. That would allow more people to fit into the vehicle but makes it even more unsafe.

As the investigation unfolds, authorities will seek to answer whether the SUV was carrying migrants after they crossed the border as part of a smuggling operation, ferrying farmworkers to fields, or being used for some other purpose.

Macario Mora, a spokesman for Customs and Border Protection, said agents were not pursing the SUV at the time of the crash, which was initially rumored He said the immigration status of the passengers was unknown and being investigated.

It was an unusual number of people in an SUV, but we don't know who they were, Mora said.

The people in the vehicle ranged in age from 15 to 53 and were a mix of males and females, officials said. The driver was from Mexicali, Mexico, just across the border, and was among those killed. The 69-year-old driver of the big rig, who is from nearby El Centro, was hospitalized with moderate injuries.

The passengers' injuries ranged from minor to severe and included fractures and head trauma. They were being cared for at several hospitals. One person was treated and released from a hospital.

The crash occurred around 6:15 am at an intersection just outside Holtville, which dubs itself the world's carrot capital and is about 11 miles (18 kilometers) north of the US-Mexico border. It was a sunny, clear morning and authorities said the tractor-trailer and its two empty containers were northbound on State Highway 115 when the SUV pulled in front of it from Norrish Road.

It's not clear if the SUV ran a stop sign or had stopped before entering the highway. It's also not yet known how fast the tractor-trailer was travelling.

The speed limit for tractor-trailers on the highway is 55 mph, according to CHP Officer Jake Sanchez. The other road is also 55 mph for vehicles.

A 1997 Ford Expedition can carry a maximum payload of 2,000 pounds. If it had 25 people inside, that would easily exceed the payload limit, which taxes the brakes and makes it tougher to steer, said Frank Borris, former head of the National Highway Traffic Safety Administration's Office of Defects Investigation.

You're going to have extended stopping distances, delayed reactions to steering inputs and potential over-reaction to any type of high-speed lane change, said Borris, who now runs a safety consulting business.

SUVs of that age tended to be top-heavy even without carrying a lot of weight, Borris said.

With all of that payload above the vehicle's center of gravity, it's going to make it even more unstable, he said.

The crash occurred amid verdant farms that grow a wide variety of vegetables and alfalfa used for cattle feed.

Thousands of people cross into the US each day to work in the fields. The harvest of lettuce and other winter vegetable crops runs from November until March, and buses and SUVs carrying farmworkers are often rumbling down the rural roads s in the early morning hours.

The area has also seen smugglers carrying migrants in trucks and vehicles. Hundreds of migrants who died after crossing the border are buried in unmarked graves in Holtville's cemetery on the edge of town.
