The sausage mystery

Back at my cousin's we made sausages and buns for dinner. Wolfram, as the man, was in charge of the BBQ. Janet switched on the gas BBQ for us and Wolfram cooked.

Somewhere, somehow, one of the sausages disappeared.

Wolfram claimed it fell down but we never found it.
Not that night, nor the day after.

It might have rolled down the few steps behind the BBQ (assuming that sausage was in jumping mode) and been eaten by a coyote overnight (well that's the best explanation Janet could come up with).

PS: those chicken sausages turned out pretty good, even with one missing :)
