Details surrounding the sudden death of Dave Goldberg, CEO of SurveyMonkey and husband of Facebook COO Sheryl Sandberg, have surfaced two days following the announcement of his passing on May 2.

A spokesman for the prosecutor's office in Jalisco State revealed that Goldberg had been vacationing at a private resort in Mexico with family and friends when he collapsed while exercising at the gym and died of head truama and blood loss, The New York Times reports. Goldberg's brother, Robert, found him lying on the floor of the gym covered in blood at 4 p.m. on Friday. The spokesman believes the incident to be an accident and notes that Goldberg presumably "cracked his head open" when he fell off of the treadmill. Goldberg was rushed to the Hospital San Javier in Nuevo Vallarta, where he was pronounced dead.

Robert Goldberg announced Goldberg had "passed away suddenly" on his Facebook page, though details of the cause of his death were undisclosed at the time.

He wrote, "It’s with incredible shock and sadness that I’m letting our friends and family know that my amazing brother, Dave Goldberg, beloved husband of Sheryl Sandberg, father of two wonderful children, and son of Paula Goldberg, passed away suddenly last night. In this time of sorrow, we mourn his passing and remember what an amazing husband, father, brother, son and friend he was."

SurveyMonkey followed up with a statement released on May 3, the morning after Goldberg's death: "We are deeply saddened to announce that Dave Goldberg passed away suddenly last night. Dave’s genius, courage and leadership were overshadowed only by his compassion, friendship and heart. His greatest love was for his family.

Sandberg has not released a public statement regarding her husband's passing. Fortune reports that the family of the late executive is planning to hold a private memorial service in California on Tuesday.
