After weeks of troubles, first splitting from the CES alliance as Catania, then moving to their new headquarters and some inside problems erupting, now concluded in being shot down by Hatrickelli and Provenzano.
Hatrrickelli already owned 2 headquarters, but both could only have 50 members, and Distruzione was the lowest ranked 100 HQ in the game, and probably the easiest target for them. It's rumored that other families were behind the picking of Distruzione as target, but nothing of the sort has been really confirmed.

When Distruzione went down after a really quick and pretty clean wave, Ht is started on the empty (100) HQ in Palermo. Later Hattrickeros gets taken down, an inactive LC is sacrificed to keep some capomoney intact as both HT families move members to the new headquarters.
Provenzano takes the former Hattrickeros spot and creates Genovese on it.
