“It is with the greatest sorrow and sadness that I let you all know that John passed away this afternoon. So many people have posted messages of love and condolences on his phone. I am trying to figure out how to post on any of his fb pages. I appreciate all of your thoughts and prayers. One of his favorite quotes is, ‘All that you can take with you is that which you’ve given away.’ From reading your messages, I know he gave much away and so much love was sent to him. He passed away suddenly, but that was his wish. I had heard him over the past few weeks having lengthy conversations with many of you brought such joy to him. Thank you all for your heartfelt messages,”  his wife, Cathy shared.
