The U.S. Coast Guard has confirmed that the captain of the tugboat involved in Monday’s deadly collision, which claimed the lives of two young girls attending a sailing camp, was tested for alcohol, as part of the agency’s ongoing investigation.

One of the two girls killed has been identified as 7-year-old Mila Yankelevich, the granddaughter of an award-winning Argentinian TV producer, Cris Morena, according to La Nacion. The Argentine Consulate in Miami confirmed her identity with Fox News Digital. 

“With regard to the accident that occurred in the city of Miami, the Consulate General and Promotion Center of the Argentine Republic has been informed of the incident and remains fully available to assist the family members who reside within its jurisdiction,” the consulate said in a statement to Fox News Digital.

Yankelevich’s grandfather, Gustavo Yankelevich, and father, Tomas Yankelevich, are also producers, while her mother, Sofia Reca, is an actor, the Argentinian outlet reported.

Florio also confirmed that the investigation will include the Miami Yacht Club, from where the girls launched their sailboat as part of a summer camp program.

The popular sailing program, started in 1927, boasts of summer camps in a “very secure area at the Biscayne Bay,” their website says. Biscayne Bay is a heavily trafficked waterway, serving commercial shipping, recreational boating, sailing camps and clubs and fishing and diving.

The Miami Yacht Club shared on social media that they were cooperating with law enforcement. Fox News Digital has reached out to the Miami Yacht Club for comment.

“Out of respect for the families impacted and to allow for the necessary response efforts, the Miami Yacht Club campus, including all our partnering organizations’ facilities, will be closed until further notice,” they said.

In another statement, they wrote: “The Miami Yacht Club is more than just a campus of organizations on the water – it’s a family – and today, we share in the deep grief of our extended sailing community family. Our thoughts and prayers are with the families, the sailors, and the dedicated instructors and volunteers who give so much to this program.”
