There is not much info on his early days, I´m afraid. He pretty much flew under the radar until the Kefauver hearings in the early 1950s. He was born May 26, 1904 in New York (Harlem). His father Salvatore and mother Giulia had immigrated from the Calabrese region of Italy. In 1923, he was sentenced to 5 to 12 years in Bronx, NY on a charge of 2nd degree robbery. By 1935 he was reported ro be one of the heads of a policy gang in Westchester County, NY. He was also reported to be the head of a numbers racket in the Bronx and Yonkers, NY. In 1952, Alo plead guilty to the operation of gambling casinos in Broward County in Florida and fined 1,000.00 dollars. Alo freely admitted that he made his money as a gambler.

According to the Mafia Monograph, Alo was during a meeting at a hotel in NY in May of 1956, selected by 35 identified top mobsters (probably all members of the Genovese Family, none of them were named) to run the Family in Costello´s absence. By that time, Alo was a captain in the Family and head of a huge crew.

It is said that Alo was somewhat of a lackey of Lansky, his right hand man (as you put it). But I don´t buy into that. Although a business partner of Lansky, I think Alo was assigned to Lansky by the Genovese bosses actually to keep a close eye on him. I could be wrong though...
