If you feel like people need to be comforted, comfort them. I'm sorry to hear about it. My graduating class was cursed. We lost 6 people within four years. Half of those being murders and the other half being freak accidents. I understand how hard it is and how awkward it can be. If you feel like anyone needs a hug, hug them. It's going to be very hard for them for a little while. It's a dose of mortality that no young person wants.
