Kelly's love and life will always be remembered. I will be taking some time to be there for my children who have lost their mother, so forgive me in advance if you don't hear from us for a while.  But please know that I will feel your outpouring of love in the weeks and months ahead as we heal."

Actor Daniel Dae Kim, who appeared alongside Preston in For Love of the Game, wrote, "I was lucky enough to work with her on one of my very first films, For Love of The Game. We were shooting on cold days in Colorado, but she couldn't have been warmer or kinder to a young, nervous actor trying to make good. I'll never forget that. Thank you Kelly."
