Here is a picture of the area...

#1 marks the Smart Home (the home is to the left of the #1)
#2 marks the street where the Doctor lives that heard the scream late that night.
#3 marks the area where I believe the Doctor heard the scream coming from.

If anyone thinks my rattlesnake bite thought is not possible... just look at the terrain here and the deseret conditions. Remember we know they left on foot from the home. Did he have a car parked somewhere in the #3 area. Was the scream possibly coming from Liz being after she step too close to a snake laying on warm ground surface to gain warmth and then was bit by a snake and that is why no ransom demand was made? It just a thought... not that any of you have to believe it.

Or possibly the scream came from open area just south of my #1 in the picture. Maybe the doctor lives in the home to the bottom left corner of the #2 in the picture.

I will leave the picture up on my server for a couple of days. Then I will remove it. If you want it right click on it and save it to your own hard drive.
