I see. But the thing that bothers me most is that I feel nothing towards this event.

Unsurprising. You didn't know the person, you weren't present for the news, you missed all of the shock. For you the feelings may come much, much later -- or never at all, I mean, it's not something you experienced in any way, you essentially just heard about it, like a radio show. Yes, it's a sad thing, but you're not weird for not feeling sad about it. The worst thing you could do is pretend.
