Alvor has quite the high tendency to die during attacks on the village, be it by dragon, vampire, or feral chicken. You can ressurect him if you're on PC.

A tip from someone who had seen him die all too often, be sure, when you want to get to the village, to fast travel not to Riverwood, but to a nearby location like the Guardian Stones, and to get there by foot.
