Yusiel Lopez Insua, a 46-year-old tugboat captain, has entered a guilty plea to charges of seaman’s manslaughter following a tragic incident near Miami Beach in July 2025 that claimed the lives of three young girls. The U.S. Attorney’s Office for the Southern District of Florida confirmed that Insua originally pleaded not guilty but changed his plea on July 21.

The incident involved Insua’s tugboat colliding with a sailboat occupied by the young girls, aged between 7 and 13, who were attending a youth sailing camp at the time. Among the victims were Mila Yankelevich, 7, Arielle Buchman, 10, and Erin Victoria Ko, 13. The collision resulted in the boat capsizing, and while two children and an adult instructor on board survived, the loss of life brought immense grief to their families.
In the plea agreement, which has reportedly been accepted by the victims’ families, prosecutors are suggesting a relatively lenient sentence of one year in prison coupled with six months of home confinement. The charge of seaman’s manslaughter carries a maximum penalty of 10 years, underscoring the severity of the case. Insua’s attorney, Walter A. Reynoso, expressed that his client wishes to spare the families further anguish by avoiding a lengthy trial.
Reynoso indicated that Insua is deeply remorseful, saying, “He feels awful about the unimaginable pain and loss suffered by the three families who lost three very young daughters.” This sentiment echoes throughout the community as they continue to mourn the young lives lost in this tragic accident.
Investigations revealed that Insua was reportedly using his mobile phone during the crucial moments leading up to the collision. Data analysis indicated activity on internet marketplaces coinciding with the moment of impact. Furthermore, Insua was operating the tugboat while pushing a barge loaded with construction debris, with a deckhouse and crane obstructing his line of sight.
Compounding the tragic situation, the sailboat that the children were on had stalled after losing wind, leaving it in the direct path of the barge. Insua failed to assign anyone as a lookout, a critical oversight that investigators believe contributed significantly to the accident.
Reynoso previously stated that Insua planned to accept full responsibility for his actions in this tragic event. The tugboat captain’s decision to plead guilty reflects his desire to acknowledge the series of errors that led to the devastating consequences that unfolded that day.
Sentencing for Yusiel Lopez Insua is slated to take place on October 13, 2026. Until that date, the community continues to come to terms with its loss, rallying around the grieving families, as they remember the vibrant young girls whose lives were cut short far too soon. The case serves as a somber reminder of the importance of vigilance and safety in maritime operations, particularly when children are involved.
