George Borgesi, 50, is said to have taken the big seat, a source told Cosa Nostra News.

The family's former consiglieri, "Georgie is not liked on the street," said the source. He added that Joseph "Uncle Joe" Ligambi, boss of the family who has been claiming he is retired, and Borgesi, who is Uncle Joe's nephew, don't get along.

"Since Georgie's been back he's had the Salvo brothers who are loyal to him grabbing everything back that was his before he went to jail.

"Uncle Joe's guys who collected [money for him], you could work with. Georgie is a stone-cold killer and it's only a matter of time before bodies start adding up. [Borgesi's] still on parole, I guess so he's limited as to what he can do [for now]."

Borgesi "pretty much put himself in that position when his uncle said he was retiring and going to Florida. Everybody is just waiting for the shoe to drop and see what's left."

"Nobody knows who to trust or who will step up when the dust clears. Scarfo Senior's guys are out but staying under the radar. It's gonna be interesting who steps to the plate."

In January 26, 2014, after 13 years in prison, Borgesi, the Philadelphia mob's former consigliere, walked away from the James A. Byrne federal courthouse holding hands with a woman he married while behind bars.

A jury had acquitted "Georgie Boy" on one count of racketeering conspiracy and said it was hopelessly deadlocked on three of four counts facing his uncle and codefendant, Ligambi. The jury cleared Ligambi of one witness-intimidation count and he was later let go as well when prosecutors decided not to put the boss of the Philly mob on trial for a third time.

Ligambi wasted no time in announcing his plans to retire from the mob, as we noted, in order to "summer in Longport and winter in Florida."

This has caused speculation about who would take over the mob. According to the source who contacted us, It seems Georgie Boy is making his move, which likely wouldn't happen unless Uncle Joe did indeed "retire."

But if George is taking the spot, a lot depends on who is backing him. If he's not well liked and still moving to reclaim territory lost during his dozen years of imprisonment, then the volatility for which the Philadelphia crime family was once well-known can return as swiftly as the time it takes to pull a trigger.

As we noted, among whatever other rivalries within the Philly mob family, the basic stage includes two generations historically at odds with each other, the old Scarfo gang and the Merlino young turks.

The ability to hold the two groups together was said to be largely due to the finesse of "Uncle Joe," who is credited for keeping the peace.

But with or without him, shifts in power are inevitable as the family's composition changes (with some members returning to the street, and others heading off to prison).
