MIAMI — Surveillance video allegedly shows Carlos Guillermo Alonso with his 42-foot Boston Whaler in Coral Gables after he unintentionally struck and killed Ella Riley Adler on Saturday off Key Biscayne.

According to Florida Fish & Wildlife Conservation Commission Officer George Reynaud, Ella was in the water after falling off a wakeboard waiting to get back on a 42-foot Hanse Fjord.

Alonso’s attorneys claim the 78-year-old experienced boater was passing by and did not realize he had struck and killed the 15-year-old Ransom Everglades student.

Ella’s funeral was on Monday at Temple Beth Sholom in Miami Beach. FWC investigators found Alonso’s boat and seized it on Tuesday, as the investigation continued.

The FWC released a report on Wednesday identifying Alonso, who was cooperating with the ongoing investigation. It’s unclear if Alonso will be facing any charges.

Ella, a Miami City Ballet ballerina, is survived by her parents, Amanda and Matthew Adler, and her paternal grandfather Michael Adler, the U.S. Ambassador to Belgium.
