Here's a snippet from a message that came from Stew Crane (SSA Gov, NV),
concerning the accident:

===
In the Mt Rose wave he found himself climbing very rapidly
again, over 1,000fpm and between lenticulars. What he did
not notice due to canopy icing at the back edges of his
canopy was that he was being blown back into cloud due to
the change in wind direction. He did turn on his artificial
horizon when he realized his predicament but, due to
instrument spin up time, it was not enough. He went full IFR
in an instant without a working horizon at altitude and
probably at or above true airspeed redline. Vertigo ensued
and in an instant he felt the wings snap off, no strong stick
forces, just a snap.
