Artie 'The Moose' Manzanero was a tough Cuneo family caporegime others being Mario DeBellis and Mikey Perroni later Mario DeBellis and Ronnie Tosca, and a vital part of the distribution racket of weapons and narcotics.
Artie Manzanero was a valued member of the Cuneo family who was given a lucrative racket at West Port Warehouse in Hell's Kitchen, which was a vital part of the Cuneo distribution network. By the late 1940s he had ammassed a sizable amount of bodyguards who guarded his position. However, to avoid detection, the warehouse usually remained sealed, and the Corleone family were even allowed to station several crew members there to ward off suspicion.
In 1948, Sonny Corleone and Soldier Aldo Trapani took down Manzanero's network, defeating the capo in Caruso! club and interrogating a racket boss before assaulting Manzanero directly, bringing down his warehouse and forcing him to do business with the Corleone family.
Manzanero's fall was one of the factors that decided the fate of Sonny Corleone, losing their main racket persuaded the Cuneos to join the Barzinis in Sonny's assassination. His fate at the end of the Five Families War is unknown but presumably with the Cuneos making peace with the Corleones he carried on running the West Port Warehouse giving a percentage of his profits to both Families.
