It’s like a nightmare, that we will never be able to wake from…It is with the heaviest of hearts that I say goodbye to my beautiful cousin, John Boy. This past Saturday October the 26th at 3am, his life was taken by a hit and run in Fort Lauderdale, FL. Though I must take comfort in knowing that he is at peace with our Lord, I also know the agony our family is going through, knowing someone hit him head on and just left him there to die. My sweet cousin, I love you so much. This world was a better place with you and your kind, creative heart in it. We will never forget you and will carry you with us forever. My family and I are pleading for any information which could help support the investigation into the tragic death of this incredible man. I ask that whoever did this, has the dignity and strength to come forward. Our God is a loving and forgiving God, but I pray for justice for John Boy and closure for my family. #JusticeForJohnBoy
