A lawsuit has been filed against Greyhound in Sacramento, Calif., by six passengers injured in a fatal bus accident last week. The lawsuit claims that the driver “did not not fulfill his duty to transport the passengers safely.” Another passenger, who is not part of the lawsuit, has made statements that he believes the bus driver was speeding just before the accident occurred, which killed six people. The accident is still under investigation, and the speed of the bus has yet to be determined. The lawsuit seeks unspecified damages.
