Friend found dead today.

A friend of mine was found dead today, setting in his Ranger side by side ATV.  He was a Vietnam vet, a farner and he and his wife are going through a bitter divorce.  The coroner said from appearances, he died of a heart attack.  He was a couple of years younger than I am.
He has been under a lot of stress with farm boundry line disputes with his neighbor,  he had got mad and fired a gun in the air, primarily for shock value, charges were filed against him for attempted murder. He was afraid that he was going to have to spend jail time for the dispute and attempted murder charges, against him.  I knew him for years and if he would have wanted to kill someone, he could have done it easily, because he went through hell and back in Vietnam. 
He and his wife were in a bitter divorce, fighting over assets, etc. and he was also trying to farm as well. I guess it was just too much for him.
Arrangements are incomplete at this time.  This is so sad. I am sorry for his family.
