Gunmen kill 3 immigrants and injure 2

From Times Wire Reports

Gunmen stopped a pickup full of illegal immigrants near Tucson, shot some and took the rest captive in an attack that left three people dead and two wounded, authorities said.

Officials had not determined who the gunmen were but believed at least two of the immigrants were Guatemalan. They believe that the driver, who they said was probably a smuggler, escaped along with a guide.
