Hi y’all, I’m looking for advice how to or what to say to my nephew, he is 22, his best friend was shot and killed while he was just sitting in his car a few nights ago. He’s pretty decimated with grief, I don’t know what to say to him.

I think some of us here, lost friends, best friends, at a young age, and I wonder if you can help me know what I can say to him, please?
:/
It’s so sad and I don’t know if they have any suspects yet, but the cops are working on it, I think.
