4 dead identified as cause of California bus crash probed
ATWATER, Calif. — A husband and wife travelling from Mexico to see their daughter in Washington were among the four identified Wednesday as those killed when a bus slammed into a highway sign that tore through the vehicle in California’s Central Valley.
The identities were released as investigators started piecing together what led to the crash early Tuesday. Among the possible factors being examined are driver fatigue and mechanical problems.
“At this point we don’t know what occurred immediately before the crash,” said Don Karol, a senior highway accident investigator for the National Transportation Safety Board.
Driver fatigue is a natural place to look considering the collision happened around 3:30 a.m., said Henry Jasny, senior vice-president of Advocates for Highway and Auto Safety.
