Anastasia was called on the carpet and questioned about Vince Mangano´s disappearence by the Commission. When he spoke, his cleverly chosen words (probably instructed by his good friend Frank Costello) told of niether denial nor guilt. He hinted that Mangano had been plotting to kill him. Frank Costello also spoke before the Commission and vouched for him. So Anastasia survived by claiming selfdefence (a tactic that Genovese wanted to use later to justify the planned rub out of Costello) but never admtted to the rumors that he was behind the Mangano disappearence.
