Biotech millionaire, UM donor owns boat towing teen girl killed off Key Biscayne, records show
The boat towing the Ransom Everglades student who was killed in a Biscayne Bay boating accident earlier this month is owned by a renowned biotech entrepreneur who lives in a $23 million Miami Beach home, is a University of Miami donor and owns a 182-foot superyacht in addition to the vessel involved in the accident off Key Biscayne, the Miami Herald reported.
Jonathan Rothberg, 61, who made his fortune through several geonomics and medical device companies he founded, is the owner of the black 42-foot 2017 Hanse Fjord that was towing 15-year-old Ella Riley Adler in the water when she was struck and killed by another boat near Key Biscayne’s Nixon Beach, according to international, federal and state records.
While marine authorities have identified the boat owner who they say left the scene after hitting Ella, a freshman at Ransom Everglades School in Coconut Grove, they haven’t yet named the owner of the vessel on which Ella was spending the day with friends on the water.
