Frankie Diamonds was a former member of the Nomad charter who transfers to SAMCRO.
Biography
Season 5
He gets patched into SAMCRO from the Nomads and is part of the crew who attacked Unser. (Sovereign)
In Authority Vested it is shown that Frankie along with his fellow Nomads are seen getting rid of Clays safe, heavily implying they are behind the home-invasions.
He hires two black men to try and kill Jax and to get the heat off him. They get a call from Nero Padilla that he needs Jax to come down. When Jax and Chibs go to the brothel, Frankie is holding Nero hostage. Nero gives Frankie $130,000 and a "couple of good watches", and then Frankie made Chibs drive the get away car Frankie got from Nero then when he was done he hit Chibs in the back head with his gun and gets in a car and leaves.
Now knowing the full truth of Frankie's involvement with the home invasions as well as the attempt on Jax's life, SAMCRO takes a vote at "church". The decision is unanimous to both strip Frankie of his patch as well as introduce him to "Mr. Mayhem" (murder him). When the rest of the Club leaves the table, Jax confides in Bobby alone that Frankie cannot be killed right away. Lt. Roosevelt has informed Jax that there is an informant at the table, and he will only reveal who that is once Jax delivers Frankie to him so that he can exact revenge for his role in the murder of Roosevelt's wife (who was murdered during a home invasion on her house). (Authority Vested)
SAMCRO finally tracks down Frankie Diamonds in Tahoe, where he is being sheltered by the Italians. Upon being told that SAMCRO is enroute by an Italian enforcer, Frankie shoots and kills the Italian just as the Club arrives. Regardless of Jax telling everyone not to kill him, Frankie is gunned down by another Italian who walks in and sees his associate dead.
