evidence: Tafari Campbell, 45, "was employed by former President Obama and was visiting Martha’s Vineyard at the time of his passing," according to a Monday news release from Massachusetts State Police. [...] "Tafari was a beloved part of our family," said the Obamas in their statement. "When we first met him, he was a talented sous chef at the White House – creative and passionate about food, and its ability to bring people together. In the years that followed, we got to know him as a warm, fun, extraordinarily kind person who made all of our lives a little brighter." "That’s why, when we were getting ready to leave the White House, we asked Tafari to stay with us, and he generously agreed. He’s been part of our lives ever since, and our hearts are broken that he’s gone," the statement continued. "Today we join everyone who knew and loved Tafari – especially his wife Sherise and their twin boys, Xavier and Savin – in grieving the loss of a truly wonderful man."
