Dave Goldberg, 47, was exercising at a gym in a private resort in Mexico, according to a source close to the family. "He fell off the treadmill and cracked his head open," says a Mexican government official. USA Today spoke with the prosecutors' office in Nayarit State, which says he suffered an inch-long head wound. Goldberg's brother, Robert, found him on the gym floor surrounded by blood around 7pm; USA Today frames that as hours after Goldberg fell backward. Goldberg was transported to the hospital, where he died of blood loss and head trauma. Goldberg, the chief executive of SurveyMonkey and husband of Facebook COO Sheryl Sandberg, was on vacation close to Punta Mita, near Puerto Vallarta, with friends and family. Meanwhile, the outpouring over his death continues on Facebook, and the Walt Disney Company (where Sandberg is a board member) plans to change the time of its quarterly-results release today to work around Goldberg's funeral in California.
