AP source: Goldberg died after collapsing in gym
David Goldberg, the SurveyMonkey CEO who also was Facebook executive Sheryl Sandberg's husband, was exercising at a gym in a Mexican resort when he collapsed before he died Friday, a person close to the family says.
The person asked not to identified because they weren't authorized to speak publicly.
Efforts to revive Goldberg, who was vacationing with family, were unsuccessful.
The source says family is planning a service in California but no other details are available.
