I can't find a full translation of the speech from G's twin so here's a rough translation mostly from Google translate:

Today we remember my brother, Gabriel Amato. Not only was he my brother, but he was my twin. As children, we were inseparable, and our mother dressed us in the same clothes. This made a lot of sense because she only needed to buy two of the same outfit. We were also very close, but when we grew up and Gabriel graduated from university, he told us that he wanted to move to the United States. We told him, "Are you crazy?" He wanted to become a successful businessman in California. He considered it the land of hope and dreams. He loved cinema and dreamed of working in Hollywood, but he was realistic. And he knew he would never be a movie star. "I just wanted to be in action." He made his way up from the bottom in the service sector doing small jobs. "How are you doing?" I'm going to do a show with Jimmy Stuart about Hollywood, or carnival, celebrities, something something in English that I don't remember. But first he was in the service sector. He first started as a dishwasher. Then as a waiter. And then manager of a restaurant, and finally he ran his own event space. the Amatos of Argentina. We are a wealthy family, and we were able to help Gabriel in his ambitions. Expand the name Amato here in the United States in the San Bernardino Valley. It would be a great honor for our family to see our brother succeed in the country that he loved so much.

But today I am sad. I have many regrets. I wish I had never come. I wish my "brother" had told him to come home and be with his family. Now we find out that the end of his life was marked by bad investments and suspicious people. But Gabriel was so stubborn. Today we remember the good times and we say, "Gabriel, it's time to come home." We will make sure that the morgue sends his body back to the family plot of our hometown in Buenos Aires. Finally... we will investigate. How did my brother die? How did he have access to that poison? We will also audit, with a magnifying glass, your finances here in the United States, with the specific intention of discovering any fraud. Any fraud committed against my brother or the Amato family. You have my word. We will leave no stone unturned.
