Ten illegal immigrants "stacked like wood" in the back of a sports utility vehicle crammed with at least 27 people were killed when the driver lost control and rolled over on a remote southern Arizona highway, authorities said Sunday.

The heads were found with messages addressed to rivals of the killers, who were assumed to be involved in Mexico's bitter and violent drug war.
Armed to the hilt, they came from land and air, determined to restore order to Mexico's most violent city.
