In addition, it is quite possible that the Guido gang allegedly received their heroin shipments from both the Buccieri and Elmwood Park crews (I dont have any straight answer except of "guilty by association") since one of the Guido brothers Louis was allegedly connected to Outfit dope peddlers such as Angelo LaPietra, Rocky Infelice, Joseph and Fred Coduto, Chris Cardi, Albert Sarno, Mike and Frank Carioscia, Frank Micelli, Alex Micelli or Micelle, John Pellegrini, Anthony D'Agostino and Frank Milazzo. For example Chris Cardi was an ex-policeman and together with his constant companion Al Sarno mainly worked as musclemen and loan sharks for Outfit capo Joe Gagliano who belonged to the Elmwood Park faction under Tony Accardo and Jack Cerone.

By 1965 most of the main players such as Louis Guido, D'Agostino, Pellegrini and Milazzo were all thrown in jail on narcotics charges and received sentences between 10 and 12 years in prison.

In 1970 Frank Carioscia, Fred Coduto and Louis Guido somehow won their appeals and they were released from prison and in no time all of them were back in business, but now the main overseers were Outfit guys such as Rocky Infelice, Carl Fiorito and Fred Coduto. On February 22 and 23, 1971, some of the crew members such as Coduto, Carioscia and Louis Guido were arrested by federal agents and charged with violations of the federal narcotics laws and one week later one of their "leaders" Carl Fiorito was also arrested by the feds.

The court held mandatory release revocation hearings for Coduto, Guido, and Carioscia and so the board of parole revoked the releases of all three individuals and so Fiorito received 12 years in prison, while Louis Guido, Coduto and the rest of the gang all received 10 years sentences.

In 1972, the imprisoned Louis Gudio still oversaw his dope business from prison mainly with the help of his new wife Mary Guido, since his ex-wife previously testified for the government against him and his crew. Another individual that helped in continuing Guido’s operation was his brother-in-law John Skeva, who in turn was connected to another street dealer and old associate of the Guido gang, known as Joe Russo who in turn allegedly had many political and business connections. Reports say that by 1972 the crew still distributed around 30 or 40 kilos of heroin per month.

in no time the feds realized that the “head” of this whole operation was in fact the imprisoned Guido and so they quickly devised a plan by infiltrating one of their own undercover agents as a prison inmate, so he can get closer to their target. While in prison, Louis Guido unknowingly approached the DEA agent and proposed the purchase of white heroin from his wife Mary and his brother-in-law John Skeva. In a matter of days, the whole crew was arrested and later convicted for conspiracy, transportation and selling of narcotics and Gudo received additional years in prison.
