MIAMI – A tugboat captain has been charged with seaman’s manslaughter after operating a barge with obstructed visibility and without a proper lookout, resulting in a fatal collision in Biscayne Bay that killed three children.
“Our hearts are with the families of the children who lost their lives in this tragedy,” said U.S. Attorney Jason A. Reding Quiñones for the Southern District of Florida. “This information alleges a preventable loss of life on our waterways, including the failure to follow basic maritime safety rules and cellphone use during transit at or near the time of the collision. We will present the evidence in court with care and professionalism. As in every case, the defendant is presumed innocent unless and until proven guilty beyond a reasonable doubt.”
According to court records, Yusiel Lopez Insua, 46, of Miami, was piloting a tugboat pushing a barge loaded with construction debris across Biscayne Bay on July 28, 2025. The vessel’s forward view was obstructed by a deckhouse and crane, and no one aboard was assigned as a lookout.
At the same time, a children’s sailing camp was operating nearby. A sailboat carrying one counselor and five children lost wind and stalled in the path of the tugboat and barge. Due to the obstructed visibility, and lack of a lookout, Insua did not see the stalled sailboat before the barge struck it.
A forensic review of Insua’s cellphone revealed internet activity during transit, including at or near the time of the collision.
The counselor and two children escaped after being dragged under the barge. Three children were trapped in the wreckage and drowned.
Insua is charged with seaman’s manslaughter. If convicted, he faces up to 10 years in federal prison.
U.S. Attorney Reding Quiñones; Special Agent in Charge Edward L. Songer of the U.S. Coast Guard Investigative Service (CGIS), Southeast Region; and Captain Frank J. Florio III of U.S. Coast Guard (USCG), Sector Miami, made the announcement.
CGIS, Southeast Region; USCG, Sector Miami; and the Florida Fish and Wildlife Conservation Commission (FWC) are investigating the case. U.S. Attorney Reding Quiñones commends the valiant rescue efforts of the Miami-Dade Sheriff’s Office, the Miami Police Department, and the Miami Beach Police Department.
Assistant U.S. Attorneys Michael Gilfarb and Daniel Rosenfeld, along with Special Assistant U.S. Attorney Tanner Stiehl, are prosecuting the case.
An information is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
