The county animal control people patrolled the area and volunteers searched every day. Someone brought a bloodhound that was able to pick up some of Stewie's scent one time, but couldn't pick it up again on subsequent days. There is a live trap in that area in case Stewie would come around.

Finally, in today's newspaper it was announced that the search for Stewie is being called off because he hasn't turned up. Everyone's pretty sure that he's been eaten by coyotes. They say the scent that they picked up might have been when he was very frightened, and then he got eaten, and that explains why there was no sign of him after that.
But we are all hoping that he found a good new home with people who don't realize someone is looking for him.
someone swooped him up and took him home. I hope so.
