Friends and family members gather Sunday at a makeshift memorial on the site of a deadly charter bus accident Friday that killed 17 people and left at least eight others in critical condition in Sherman, Texas. Also on Sunday, a bus run by the same companies linked to the deadly Texas crash and being used by pilgrims heading to the same festival as the 17 Texas victims failed an inspection and was pulled out of service in Carthage, Mo., authorities said. The Federal Motor Carrier Safety Administration ordered Iguala BusMex and Angel Tours Inc. to cease commercial operations Sunday, finding that the companies posed an "imminent hazard."
