I am so sorry that this ended the way it did. My heart does break for you and your family. At least they have the perp, and there will be justice for your Father. I know that this will not take the pain away or bring your Dad back, but I do hope that it will give you some solace.
You and your family are in my prayers.
You have my deepest sympathies.
I am so sorry to learn this about your dad. Your family is in my prayers.
