A murder in the family..

It has been about 2 weeks since my first post, and here I am in a whole new world. I come from a very dysfunctional family first of all, but even this is far from what I thought they were capable of. My mother had 4 children and struggled with drug addiction her entire life. Leaving my siblings to grow up in different homes.My sister and I went to our grandfathers, my brothers to their grandmothers. Fast forward to our teens, now there are a lot of families out there who have "that" uncle.. well we were no exception. Over the years my sister and I came to accept and forgive all the wrongs, never to forget. Which makes me feel like there is no excuse for what happened. On the 11th of this month , while my brother and uncle were at my moms using drugs and hanging out, my brother (for reasons unknown to me) killed my uncle... hit him in the head with a hammer and killed him. My emotions since are very hard to describe, very surreal... Unsure of what to expect, and while it seems some family members only have their minds on my grandpas money, I cant help but think of his heart, at how it must be breaking at the loss of his only biological son. I look at how he is close to 90 years old, WW2 Army, Malaria, skin and bladder cancer, 2 strokes and a pacemaker and has yet somehow come back stronger than ever. This though... it's different. I don't think his heart is strong enough for this loss... Please pray for my entire family, for not only the good but the bad as well. For we are all in need of strength and salvation.
