Giacinto was a first cousin of Domenico Arcuri Sr.(died 2013).
He had been close to Leonardo Cammalleri and by extension the Cammalleri family of Toronto.
He was also related to a Giuseppe Arcuri of NY who has been listed as a Bonanno soldier who died June 2001.

Is this the same person?
if so,
What is his connection to Gerlando Sciascia?

Chapter 2. VENDETTA

Gurreri, Cammalleri, Salvo and Arcuri stood trial in the Assizes Court of Agrigento, the capital of the province of the same name. When called to testify, Antonino Manno made no secret of his contempt for the institution and refused to answer the prosecution’s questions. Leonardo Cammalleri and Leonardo Salvo were sentenced, in absentia, to life in prison. But during the trial, a letter from a priest in Montreal had reached the court. The clergyman wrote that Giacinto Arcuri had just been killed in a traffic accident in Canada. What the letter didn’t make clear was that the dead Giacinto Arcuri was not the same man as the Giacinto Arcuri on trial for murder. The Sicilian authorities asked no questions, however, and closed the case, thus confirming the wisdom of the Sicilian proverb “a friend with influence is more precious than a hundred pieces of gold.”

The accused Giacinto Arcuri had not been killed in any road accident. He was alive and well in Montreal and would eventually move to Toronto. (Thirty years later, after his conviction for the murder of Giuseppe Spagnolo had been rendered moot because of his presumed death, he would be among those posting $2.5 million bail for mobster Gerlando Sciascia as he awaited trial on heroin trafficking charges.)
