Investigators were checking videos, track conditions and maintenance records Wednesday, Aug. 22, 2012, to find the cause of a deadly train derailment in Maryland and figure out if Nass and Rose Louese Mayr, sitting on a railroad bridge over the town's main street, contributed to the crash or if their presence was just a tragic coincidence.
