I am so sorry for your loss. It is always hard when losing a loved one, especially as a result of a tragic event. The Bible shows that many tragedies are the result of "time and unforeseen occurrence". Ecclesiastes 9:11. The Bible holds promise that we have the hope of seeing our loved ones again. John 5:28, Acts 24:15. I hope that you find comfort in reading these scriptures. My prayers are with your family.
