KNOXVILLE, TN - As investigators continue to sort through the details of a horrific church bus crash in Knoxville, Tenn., question remain about the bus itself.
Sources said investigators have not confirmed whether the bus was registered with the U.S. Department of Transportation by Front Street Baptist Church.
Pictures of the bus from the crash scene showed no USDOT registration number on the bus and a search for safety records turned up no results on the website of the Federal Motor Carrier Safety Administration (FMCSA). Federal regulations, however, suggest the bus should have a USDOT registration number.
