Carers for the world's most intelligent gorilla claim she was 'close to tears' following news of Robin Williams' death - 13 years after video captured the two becoming fast friends
News of Robin Williams' untimely death hit particularly close to home for famed sign language gorilla Koko, who handlers say was moved nearly to tears by the somber mood shared by all at her Northern California home.
Staff at the Gorilla Foundation were, like much of America, in mourning after hearing the news Monday. Williams visited their center in 2001 and quickly befriended Koko, making her laugh for the first time in six months.
So when they explained to Koko, who is fluent in American Sign Language, that a dear friend of the center had died, she soon became sad and is pictured sitting hunched over with a quivering lip.
