"In death, he is like an apparition. He shows up inconspicuously, tactfully, in a way he never did in life. No matter how deep you look into his past, you won’t find much because most of what he did was impromptu, without a script. He lived in the present, unencumbered, and he left behind a trail of anger and destruction." (From: "Mario Santiago: Infrarrealist and Terrorist", by Ilan Stavans)
