TUCSON -- Three people in a sedan were killed early Tuesday when it struck a school bus head-on on a highway west of Tucson.
A spokeswoman for the Arizona Department of Public Safety says two of four students on the bus were taken to a hospital for treatment of minor injuries. Two adults who also were on the Altar Valley School District bus heading to Flowing Wells High School in Tucson were not hurt.
Two men and a woman in the westbound sedan died at the scene when the driver apparently crossed the center line on State Route 86 just after 6 a.m. and hit the bus.
The highway was closed for more than three hours.
