Which Iannece kid was the one who supposedly went in and hugged and kissed Scarfo Jr, signaling the shooter (supposedly Merlino) to his seat in Dante & Luigi's?

I never really believed that theory myself as I know one of the Iannece kids were also really close to Scarfo Jr, during his coming up, when his father still had a hand on things. Theres pictures of them together and he's seen in some of the Scarfo Jr. court footage where he's wearing that trenchcoat. Coulda just been a big coincidence.
