It may be about a week before Arkansas State Police complete their report on the tour-bus crash that killed 14 people from Chicago. The motor coach crashed Saturday morning in Crittenden County on Interstate 55. The bus was on its way to Tunica, Mississippi. The National Transportation and Safety Board is still investigating the crash. That probe will be complete some time after the state police report. Fifteen passengers injured in the crash remain hospitalized at Little Rock and Memphis, Tennessee. Many victims are in critical condition. Among the injuries they are suffering from are collapsed lungs, broken hips and head wounds. Police have not yet revealed a cause for the accident.
