On Tuesday, the sailboat involved in the fatal crash that killed two girls near Miami Beach was removed from the scene, along with the construction barge that collided with it. The U.S. Coast Guard confirmed Tuesday that alcohol and chemical testing had been completed and that results were pending.

Dr. Adrian Mesa, who identifies himself on social media as a mental health professional, said his daughter, who works as a camp counselor at the Miami Yacht Club, witnessed the crash. He said she told him everyone felt helpless as they watched it unfold.

A total of six people — one adult and five kids — were inside the sailboat when it was hit by a barge near Hibiscus Island, according to the U.S. Coast Guard.
