SALT LAKE CITY (AP) — A driver has been charged with illegally smuggling immigrants through Utah for work in Chicago after four men died in a highway van crash near the Colorado line.
Investigators say the 36-year-old Elvis J. Quintanilla-Vasquez picked up the seven men in California.
Utah Highway Patrol officers on Friday identified three victims as 19-year-old Freddie Sanchez-Garcia, 32-year-old Rueben Alberto Perez- Manriquez and 30-year-old Efrain Morales Carteno.
They are withholding the fourth person's name until his family is notified.
Two of three injured men are in federal immigration officials' custody; the status of the other is unknown.
The Salt Lake Tribune reports (http://bit.ly/1gXUVUX) officials found no valid U.S. identification on the survivors or the deceased.
A survivor told investigators a female passenger ran from the crash.
Quintanilla-Vasquez is in Mesa County jail.
