I agree on everything you said, although I think I have some different opinions regarding specific individuals.

First, here are some alleged associates or members of D'Amico's crew from 1989 until 1995/96:

- Marco D'Amico (crew leader)

- Tony Dote (lieutenant)

- Carl Dote (EP/Grand)

- Robert Abbinanti (related to D'Amico)

- Roland Borelli (i think he later turned informant against D'Amico)

- William Tenuta (EP)

- Rick Rissoulo (dont know shit about this guy)

- Frank Catapano (Schiller Park)

- Robert Scutkowski (EP)

At first, D'Amico probably reported to Andriacchi, but when the latter one allegedly became underboss for Monteleone, it is quite possible that Pete DiFronzo became the new capo for the EP crew, followed by his alleged successor Rudy Fratto. Im not sure if Messino was active during the 90s,although he was allegedly D'Amico's mentor. I also think that Messinos kids (or nephews) continued the "tradition" while he remained as literally broke "former" member.

I have similar opinion regarding Gary Gagliano, meaning he either reported to his capo or had direct contact with DiFronzo and Andriacchi, same as Pete and Joe DiFronzo. As for Castaldo, I dont know much regarding his activities during the early 90s, except that he was over 60 years old and allegedly controlled a loan sharking operation together with another possible and old EP member Joe Lombardi.

Spina was allegedly "hardcore" member who had two brothers and they came from the Near West Side and also knew Lombardo since "day one". The difference was that Spina was mainly involved in white collar crimes or corruption such as garbage collection, trucking operations, traffic signs etc. Who knows, maybe thats why both Lombardo and Centracchio saw the future in him.

As for the Chinatown crew, LaMantia was definitely under Monteleone who in turn reported to Jimmy LaPietra. Also, im not sure if LaMantia ever became official made guy, similar to D'Amico's situation.

Again, hope this helps.
