Sarno is in custody from a 2010 federal conviction and was sentenced to 25 yrs in prison which leaves Cataudella as the last man standing. OUTFIT leadership has always been hard to establish as this report is refuted by some Mob watchers."


That was probably the Mutt and Jeff article in the Sun Times.
here's a link:
Mutt and Jeff

A lone disgruntled guy seems to be the source of that info
The article says:
"A confidential FBI informant, who felt abandoned by the Outfit and was motivated to talk, told the feds in 2007 that Mutt and Jeff “were the current Outfit bosses in the Chicago area,” according to the previously sealed federal document."

And

"While one informant put Sarno and Cataudella at the top of the Chicago Outfit, another informant advised the FBI that Sarno was still turning over money to reputed Outfit underboss John “No Nose” DiFronzo, also known as “Johnny Bananas.” Another source of information noted that Sarno was higher in the leadership structure and collecting money from reputed 26th Street crew boss Frank “Tootsie Babe” Caruso.

Marcello himself called the two men “Mutt and Jeff” in one jailhouse conversation, secretly recorded for the Family Secrets investigation."
