JK was a year behind me in school, but I remember him well as the loveable "egghead" with the insatiable curiosity. He suffered a devastating loss in young manhood, & I am so happy to know that he went on to have a successful & fulfilling life. I found him on the internet in a Volpe article & recognized him instantly. He always held his mouth that way! Rest well,  JK! Blessings to family.
