Sal Barsconi was a pre-War mob boss who is mentioned in Fallout 4.
Barsconi and Eddie Winter attempted to improve North and South Side relations, but their efforts resulted in failure. The first major problem was Montrano betraying Winter's crew during a job, which resulted in Montrano's death on Winter's orders. The second problem was when Barsconi's crew shot up the Danvers theater, resulting in the deaths of many innocent civilians. Winter was astonished by the violence, and suggested that he and Barsconi have a sit-down to discuss the issues.
Sal Barsconi is mentioned only in Fallout 4.
