Young couple encounter a rancid smell

The witness and his wife drove a short distance from a relative's home to their trailer to pick up diapers for their baby. At the house they found their penned hounds barking unusually and noticed a strong rancid odor at the back of the house. They collected the diapers and left without further investigation that night. The following evening they heard a television news account of a nearby sighting that also mentioned a rotting-meat smell.
