A Miami boat captain is charged in the deaths of three girls who were aboard a sailboat he ran over and "crushed" while operating a large tugboat last summer, federal court filings say. Yusiel Lopez Insua was the captain of a 25-foot tugboat that had been pushing a 108-foot-long construction barge during the deadly crash in Biscayne Bay on July 28, 2025, according to a criminal information charging Insua with seaman's slaughter.
