I did not know Dustin personally, but he is ours and the loss is felt by all of us. For the wife and the children, you will be in our prayers and when I can help, I will. God is good and had nothing to do with this. Reach out to Him and he will give you peace and strength to move forward.
We lost our daughter in 2007, we would not have survived the ordeal if not for the faith we had in a Holy God to help us, in a day to day struggle that has not ended all these years. Grief is a process that takes years, please reach out to your church for resources to help you through this process.
With all out condolences.
