Hays County sheriff's Lt. Dennis Gutierrez tells the San Antonio Express-News that three people were taken to a San Antonio hospital with life-threatening injuries after the crash early Friday morning. He said the other injured passengers were taken to area hospitals.
Gutierrez said the accident happened about 4 a.m. on Interstate 35 between San Antonio and Austin. He said the 72-passenger bus was nearly full.
Gutierrez said investigators were still gathering information about the crash as rush hour began.
Ruth Alanis of Dallas-based bus owner Mares Tours told The Associated Press that the company did not yet know anything about the crash.
