"We are beyond heartbroken at the loss of this sweet, gentle, good-hearted, intelligent man. He was truly a member of our family. Lee will be cherished and remembered by all who knew and loved him, both on- and offscreen, for his positive energy, infectious smile and soulful grace. We send our deepest condolences and thoughts to his family, to his friends and, most especially, to his beloved mother."
