Chase says that himself and Williams both suffered from depression, but that he could not have expected the death of his friend in an apparent suicide:
Robin and I were great friends, suffering from the same little-known disease – depression. I never could have expected this ending to his life and to ours with him. God bless him and God bless us all for his LIFE! I cannot believe this. I am overwhelmed with grief. What a wonderful man/boy and what a tremendous talent in the most important art of any time – comedy! I loved him.
