Any idea who was behind Testa's murder? According to Gravano, the whole thing was a master manipulation by Gigante to sway Philly under his control.

It makes sense seeing how when Phil Leonetti was to become underboss, he said Scarfo had to bring him to NY and get the ok from Bobby Manna (Gigante's consigliere at the time). Under Angelo Bruno, Philly was closely associated with the Gambinos, but after the dust settled it seemed they answered to the Genovese.

Any thoughts?
