I don't have all the details yet and some of these might not be 100% accurate (heard it from a friend who is a friend of the principals)...
On Sunday(?) two climbers (a husband and wife) from Littleton were attacked, shot with a shotgun, and robbed of all their gear and other possessions at their high camp on Orizaba.
The good news is that by playing dead, they survived and are recovering while still in Mexico. Reportedly the husband got hit in the chest with 18 pellets. They were camped a little ways above and well off to one side from the Piedra Grande hut. They reportedly watched this guy walk up through the boulderfield toward them for some time before they realized that he was armed. Apparently he walked into camp and without a word, shot them both. Reportedly, the guilty party has not yet been identified or apprehended.
I don't know what to think of this or what message to take away, but forewarned is forearmed (perhaps litterally).
