A 17-year-old boy injured when a car packed with illegal immigrants rolled while fleeing the U.S. Border Patrol has died, bringing to 10 the number killed in the wreck, a Mexican Consulate official said.

The boy died Friday at a hospital in Phoenix, where four other injured migrants remain hospitalized, said Jorge Solchaga, head of the protection department of the Mexican Consulate in Phoenix. A premature baby girl born to an injured woman also remains hospitalized.

The rollover happened Monday morning about 30 miles north of Yuma while the sports utility vehicle was being pursued by U.S. Border Patrol agents. The driver lost control and the SUV rolled while trying to avoid a spike strip agents had placed in its path.

The consulate has identified five of the six illegal immigrants originally sent to the Phoenix hospital, but has not released their names or the names of the dead. Solchaga said a woman remains unidentified, and one person was released Thursday.

The Suburban was packed with 20 migrants and an alleged smuggler, who is being held on a federal charge of felony transportation of illegal aliens. Federal officials said additional charges are possible against 20-year-old Adan Pineda Doval.

Pineda was jailed after a similar chase last year but was allowed to plead guilty to a misdemeanor.

Solchaga said those who remain hospitalized, two males and two females, are in stable condition, including the baby's mother. The baby girl was born by Caesarean section prematurely. He said she was nicknamed "Miracles," or "Milagros," and is in stable condition.
