Edmund Richard Hartley, the captain of the yacht towing 15-year-old Ella Adler when she was struck and killed, pleaded guilty Tuesday to two misdemeanor navigational-rule violations in Miami-Dade court. Under a negotiated deal, he will avoid a formal criminal conviction if he completes his sentence, instead serving probation and attending boating-safety training. The agreement caps a lengthy investigation into the May 11, 2024 crash in Biscayne Bay that killed the Ransom Everglades freshman.
Plea terms and penalties
Hartley admitted to two navigational-rule violations while prosecutors dropped two other misdemeanor counts. The judge ordered six months of probation on one count and another six months that prosecutors say can be terminated if he successfully finishes the first term. Hartley must also complete a boating-safety course and is barred from operating a vessel for 60 days beginning in June.
As part of the sentence, he has to pay $5,000 to the crime victims' compensation fund, starting with a $2,500 donation in Ella’s memory within 60 days. If he fulfills every condition, prosecutors may agree to set aside the plea and dismiss the remaining charges, according to reporting by the Miami Herald.
Family reaction
Ella’s parents sat in the courtroom as the plea was entered. Her father, Matthew Adler, described her as “bright, joyful, creative and deeply loved,” and said she “was flourishing” at 15. He told the judge that the family created the Ella Ridley Adler Foundation to support Jewish life, education, and the arts in her honor.
The Adlers told the court they had agreed to the negotiated plea, framing it as part of their effort to move forward while keeping Ella’s memory at the center of their work, as reported by the Miami Herald.
How investigators say the crash unfolded
Investigators say that on May 11, 2024, Ella fell from her wakeboard in congested waters near the Nixon Beach sandbar off Key Biscayne. A separate center-console boat then struck her and initially sped away. The Florida Fish and Wildlife Conservation Commission later tracked down that Boston Whaler, which was found docked behind the owner’s Coral Gables home.
Authorities charged 79-year-old Carlos Guillermo “Bill” Alonso, who in January pleaded guilty to careless-boating misdemeanors. He received six months of probation and was ordered to complete a boater-safety course. For background on the original charges, see reporting by AP News, the Tampa Bay Times, and earlier Hoodline coverage of the fatal Biscayne Bay crash.
What "withhold of adjudication" means
Under Florida law, a court can withhold adjudication of guilt in some cases so that a defendant who successfully completes probation is not treated as having a criminal conviction. The statutes limit when a withhold is allowed and spell out what happens if probation is revoked.
If a judge later revokes probation, the court can then adjudicate guilt and impose sentence, within the statutory boundaries. For a detailed explanation of those rules, see the Florida Statutes.
What comes next
Hartley remains on probation and must meet every court-ordered condition to avoid further legal consequences. Prosecutors say they will consider dismissing the case if he completes the terms as agreed.
The criminal proceedings are edging toward a close, but the Adler family still has civil options and has been vocal about the need for stronger boating-safety measures in crowded Biscayne Bay. They have cast the court outcome as one step toward closure, while their foundation work continues in Ella’s name.
