well it's been reported that new guy in chicago is from whatever's in lake county, illinois
so that would mean chicago has five crews
the detroit family marries within the family so their recruitment pool is blood related
the feds in detroit are pinching dope dealers because heroin affects affluent suburbs
Reported by who? One or two blogs? And I don't think even they positively stated anything about a "5th crew." Go read the Chicago FBI's website's recent cases. They have the resources to make cases against the LCN, to say nothing of state law enforcement.
