In Casso's book, he discusses how Testa/Senter were recruited to whack Roy DeMeo, in exchange for getting straightened out. And Gas describes how the hit went down....summarized in one of my previous posts above.

In the D'Arco book, he mentions Senter and Joey Testa getting made in the same ceremony as Joe D'Arco- Al's son. Later, when Al is the acting boss, he presided over a ceremony, where Patty Testa was made. When Vic and Gas were fugitives, Patty Testa was involved with relaying messages from the bosses to the capos, and even supplied homes for meetings to take place. Nothing earth shattering, though. It seems that Senter/Testas were mentioned mostly for the sake of name dropping.
