After this both brothers relocated their base of operations to San Diego where they became closely associated with the Matranga and LiMandri family's. In San Diego, Joe was a soldier in the crew of "Papa Tony" Anthony Mirabile and upon Mirabile's murder in 1958 became the capo of the Los Angeles family's San Diego faction.

The murder was carried out at Adamo's home in San Diego. Adamo owned the Panama and Arizona clubs in San Diego along with an interest in various bars and clubs.
