A New Sad Story Of Suicide

I am very emotional and still in shock and despair so please bear with the randomness of this post.
Monday was Nat'l Suicide Prevention Day. Of course, I thought of my mom a lot that day with the usual regrets and missing her dearly. 
I got a call early Tuesday morning that my foster nephew, David, 40 yrs of age and killed himself violently just outside the door to my old Murray, Utah home around 8:30 pm Monday night.Just a couple of hours earlier he was planning his day for Tuesday. His attitude was good. Somewhere between noon and 8:30 something happened to drastically change his goal of life to his final goal of death.  He took his military pistol from his Marine service in the first Iraqi War and blew his brains out from ear to ear. A clean shot. One he learned was the kill shot.
He leaves behind a wife and 2 step children. His death came in the middle of family turmoil in his  family.. bitterness, inner fighting, attorneys, mediation, family counseling, etc. All seemed to be going on track, some family still refused to speak or look at him and he sat alone at Christmas. But things were changing.
Then that awful, God awful thing, whatever it was, happened Monday between noon and 8:30 pm put him at the point of no forward movement in his life. As sudden as no one can grasp, he went from organized, committed to deal with his troubles and make a new life for himself and his family, to the firm decision to place 2 identical texts to 2 brothers: (paraphrasing) " Call the Murray Police. Within 20 min. I will be found dead outside my fathers house." Sadly, neither brother got the message for several minutes but they could not have saved him. He was determined to die.
Now, what was a family crisis in the process of hopeful resolution is now an all out war amongst themselves. 1 sister is totally banned from services with threats of physical violence to occur if one of his sister's attends either the viewing or services. Other people threaten to destroy and disrupt.

So many lives will never be the same. The anger is turning to hate even before they lay their disturbed brother to rest... some threatening to create a scene. How dare these small, selfish minds have the lack of moral duty to set aside for a day their differences and unite to remember and respectfully lay their brother to rest!.I am at wit's end and full of despair.
