The fiancée of a billionaire banker’s son who died while trying to save her when she went overboard during a Florida fishing tournament doesn’t remember moments of the deadly accident, officials said.

Andrea Montero, 30, hit her head at some point when she went overboard as she and her fiancé, Juan Carlos Escotet Alviarez, 31, tried to snag a sailfish from a 60-foot boat — but she doesn’t recall if the injury occurred when she fell or when she was rescued by the crew, Florida Fish and Wildlife Conservation Commission officials told the Miami Herald.

“Rough as it was, she couldn’t say whether it was when she went over or coming back in,” FWC spokesman Jason Rafter told the newspaper. “She doesn’t remember when it happened.”
