A couple of interesting things with that video that I noticed.
1) The pastor repeats the question the reporter asks, "Did you have anything to do with Sandra's disappearance?", and then looks away when he answers. Not saying he's lying, but those can be verbal and non-verbal signs of lying.
2) The pastor would not look at the reporter when she was talking to his wife. Could be another sign of lying.
3) The handyman from the mhp says that the pastor is not friendly with other residents.
4) The handyman says that Sandra was so friendly that he bets you could find her fingerprints in 75% of the mobile homes in the park.

He's probably exaggerating, but still.
JMO.
