Here's the names of all the dead and defiled characters that I found: Jervar, Ardwen, Atabah, Khayla, Ma'randr-jo, Skulvar and a dog. They were all murdered, stripped and face down on the ground. For starters, I thought that people couldn't get killed unless the player was in the same cell but there was no action when i neared Whiterun. I assumed it must've been a vamp attack but they usually attack at night and only 2-3 vamps at a time, doubtful that they could kill all those NPCs without getting killed themselves but there wasn't a single vamp corpse anywhere. Lastly there's the issue of them all being stripped and placed face down which is what really made me go "huh, WTF?"
Does anyone have any thoughts of how/why this happened? This was my first time walking back to Whiterun post 1.9 patch, did they sneak a weird encounter into the patch or something?
Also I'd like to note that the carriage driver was alive and well which made him seem very suspicious...I haven't rode a carriage since

EDIT: I just noticed Ardwen wasn't stripped but the rest were
