Is it possible to use present and past in one sentence?

Question

> In *On The Road* Jack admits to Justin W. Brierly that he loves Neal Cassady because he reminds him of his brother, Gerard, who dies when Jack was five years old. Is this grammatical? The first part of the sentence is in the present whereas the other in the past!!

Answer 1

No, it is not a grammatically correct sentence. I would presume it's a typographical error.as there are many these days with mass production of books. It should be "...who died..."
