Sandy Balestra.
She's from Ticino, south Switzerland (italian speaking part), i live not far from there.
She did only few movies with Rocco as far as i know, no other porn movies, going very extreme, then she left porn.
Rocco said that they could only send her to fuck on the moon to make something new, because she performed almost every
nasty 
act he could think of.
Last info i got is that she went into politics for a local formation and then disappeared into oblivion.
Here you can see a picture of the train wreck she is now:
