DID HE MUCK?!

[onoble]

Ok. 1/2 Live game.

On the flop I am all-in with an open ended str8 draw vs. a villian.

The villian calls my all-in and flips up his cards revealing a set.

I do not show my cards UNTIL the TURN when my str8 hits.

When I flip up my cards the villian (who is pissed as hell) throws both his cards at the dealer. One lands face up infront of Villain the other lands on the railing also face up. Both cards hit the dealer.

The river pairs the board. Dealer pushes the pot toward villian.

1) Did he muck?
2) Should I say he mucked and the pot is mine?
3) What if one or both cards landed face down?

Thanks!
