I am so sorry for the loss of your son. Although, I did not know Derek personally I do know many of his friends. I cannot fathom the depth of your loss. I have 3 teenagers myself and worry about them going out everyday. My heart is humbled by your grief and I share it with you and pray to God this doesn't happen to anybody else's child. Take comfort in your memory's of Derek and know that he will never be forgotten by any of us!
