im not sure if Massino has but Lino definitely gave a first hand account of how it went down at Massino's trial. he choked up on the stand when describing how Trinchera got shot. he ran of the place and went to someone's house to use the phone and have his son pick him up.

id love to be able to read those testimonies in full from Massino's trial. lino, frank coppa, joe d'amico, and richard cantarella all testified at one point or another and each gave their history; when they were made, who they came up under, etc

you can read quotes from Lino's testimony in sam destafno's book about massino "the last godfather"
