Answer:
In F. Scott Fitzgerald's novel "The Great Gatsby," Gatsby's father learned of the tragedy through a Chicago newspaper that he had read. He had seen a mention of Gatsby's death and decided to attend his son's funeral.
It appears that Gatsby's father did not know his son well at all. He talks about Gatsby as if he is still a boy and is unaware of his son's adult life, including his wealth and connections to high society. Gatsby's father seems to be a simple man who is proud of his son's accomplishments but also sees him as a child who is still full of potential.
