If a person gets shot 3 times, and one of those is on the face how long does it take for them to die?

You didn't say whether or not your brother died, but I'm uming he did. I'm sorry for your loss. Truth is, you may never know how long it took him to p away. The best thing to do is not to focus on his death and suffering. Honor his memory by thinking about the good times you had with him. Make a scrapbook with pics of good times, something like that. It will help you heal. Good Luck!
