On June 25, 2009, Jackson died at the age of 50, after suffering a cardiac arrest. Animal trainer Dunn, speaking to the "News of the World", said: "Bubbles definitely missed [Jackson] when they parted and will miss him now. Chimpanzees are intelligent. They remember people and stuff. Bubbles and Michael were close friends and playmates. The last time Michael visited, Bubbles definitely recognized and remembered him." He said that Jackson thought of Bubbles as his first child, and added that he hoped Jackson's children would keep in touch with their "stepbrother" following their father's death. In 2010, Jackson's sister La Toya visited Bubbles at the Center for Great Apes in Florida. According to the Center for Great Apes website, Jackson's estate "has continued to support the annual care costs for Bubbles at the sanctuary".
