Yes he officially took over not too long ago, good thing too. Tocco died yesterday, I will see if I can find a chart for you.

Here is a tidbit on the Inauguration

Underworld sources confirm that an inauguration ceremony for newly-appointed Detroit mafia boss Jack (Jackie the Kid) Giacalone, 63, has taken place since the beginning of the year in a Motor City restaurant, similar to the one that was held for his predecessor Giacomo (Black Jack) Tocco, 87, at a posh hunting lodge near Ann Arbor exactly 35 years ago last month.

More than one highly-placed street source, tells The Mob Insider that the ceremony, attended by all the crime family’s capos and high-ranking members, took place at an eatery in Eastern Market, which seems appropriate considering the region’s gangland-rich history and the Giacalones’ roots there specifically, both dating back more than 100 years.

Reports of Tocco, the longest-tenured LCN don in the United States, stepping aside and tabbing Jackie the Kid his official replacement – following a two-year stint as acting boss –, surfaced in the spring.

Locations mentioned as possible venues for the inauguration were Vivio’s Bar & Grill and The Roma Café or both.
