The mourning father of a 13-year-old girl killed in Monday’s crash in Biscayne Bay between a youth sailing camp boat and a barge is speaking publicly for the first time since the tragedy.

Preliminary information indicates a “barge struck a sailing vessel carrying six people” near Habicus Island, Florida officials said.

The two girls who died after a barge slammed into sailboat carrying five children and a camp counselor in Miami Beach accidentally drowned, the Miami-Dade Medical Examiner’s Office said Thursday.
