Sweetie, there is no sense in a senseless death. There is just no sense to be made. Which makes peace harder to find. I'm not sure we ever really get over it. Just comes in waves, like the oceans tides, the waves get smaller in time, but they still come.

Just make time to feel whatever you feel and let it come and pass over you.

Whatever happened to them likely will not bring closure for you. But your curiosity to know is very understandable.

Be gentle with yourself. Try not to judge the feelings as they arise.
