At about 3:26 Chief Shaw begins to talk about the van. The person who saw the van that was parked by the gas station around the time JH went missing, gave the description they did (in response to LE's questioning) because it looked like (CS said 'their') parents' van. That's why the witness said T&C but, like somebody pointed out, it could be another make and model. It's unclear to me if only one or two people together witnessed the van. CS interchanges the person with their, etc. He never says he or she but uses they.
He doesn't say where the witness was located, how near or how far. Just that they described the van as looking like their parents'.
Regarding the hair, Chief Shaw said it was described as being wavy.
