Captain pleads guilty in Florida boating crash that killed three girls

Yusiel Lopez Insua pleaded guilty to seaman’s manslaughter in the Miami boating crash that killed three girls from a youth sailing camp. The plea turned a case that had shadowed the Miami sailing community since last summer into a sentencing matter and forced a direct legal acknowledgment of the choices that put children in the path of a moving barge.

The collision happened July 28, 2025, in Biscayne Bay near Miami Beach, between Hibiscus Island and Monument Island. Lopez Insua was operating a tugboat pushing a construction barge that struck a sailboat carrying children from a youth sailing program. Prosecutors said the case centered on obstructed visibility and the absence of a proper lookout, two failures that go directly to basic duties on crowded South Florida waterways.

Three girls died. The victims were identified as Mila Yankelevich, 7, Erin Victoria Ko Han and Ari Buchman, 10. Buchman died Aug. 3, 2025, at Jackson Memorial Hospital after being hospitalized. The crash pulled in families, a sailing camp and Miami’s tight-knit boating community, where open-water lessons are often treated as a controlled, supervised activity rather than a place where children face a fatal collision with commercial traffic.

Under the plea deal, prosecutors were recommending one year in prison and six months of home detention. Lopez Insua had faced up to 10 years in prison if convicted at trial. By pleading guilty, he avoided a courtroom fight over whether the tragedy was only an accident or criminally negligent conduct that rose to the level of seaman’s manslaughter.

The case has also sharpened scrutiny of how vessels are managed in busy channels where recreational boats, sailboats and commercial traffic share limited water. The facts that defined this crash, a tug pushing a barge with blocked visibility, no proper lookout and a children’s sailboat in its path, point to questions that go beyond one captain. They reach into boating rules, captain vetting, camp safety planning and enforcement on the water.

Federal prosecutors handled the case, underscoring how seriously maritime deaths are treated when children are involved. For the families of the girls who died, the guilty plea offers an admission in place of a trial, but it cannot alter the sequence that ended with three children lost in Biscayne Bay.
