Nine people were killed and many more injured Thursday when a truck crossed over the median on a highway and struck a bus carrying high school students from Los Angeles on a college trip to visit Humboldt State University, The Los Angeles Times reported. A statement from Humboldt State said that the students were en route to the university, the northernmost in the California State University System, as part of the Preview Plus Program, which brings low-income and first generation students from San Francisco and Los Angeles high schools to the campus.
