Where Have You Gone, Don Carlo?

Remnants of the Gambino crime family have been reduced to shaking down hot dog vendors:

Three men — two of them Gambino crime-family associates — have been charged with shaking down a Bronx hot-dog vendor and beating him, cops said yesterday.

The men — also suspected of torching his truck — allegedly demanded $200 a week in “protection” money from the vendor and attacked him when he refused to pay.

Reputed Gambino associates Robert “Bobby Fingers” Francella, 49, and Patrick Lombardo, 47, along with Gregory Monzeglio, 44, met with the victim several times in a restaurant.

When they couldn’t collect, they beat him with a hammer on Aug. 14, and assaulted him again on Sept. 8, cops said. The vendor suffered cuts and lacerations.

The truck, parked in a vacant lot near the restaurant, was burned on Sept. 28.
