A Texas man has been indicted by a federal grand jury in Tucson for his role in a car crash in July that killed an undocumented immigrant and seriously injured two others. The U.S. Attorney’s Office says 39-year-old Moises Gabriel Castillo was driving a commercial semi-truck on a stretch of the I-10 near Tucson and carrying four undocumented people when he collided with another semi-truck and skid across the freeway.
