When was Ella Adler struck by a boat?

According to new information released in the report, Ella was struck wakeboarding in waters off Key Biscayne on Saturday afternoon.

Initial reports from the FWC indicated the girl had been waterskiing.

The agency reported Ella fell in the ocean near Nixon Beach while being towed about a mile from shore and was struck by another vessel at 4:30 p.m.

The beach is in Miami-Dade County about 7 miles south of downtown Miami.

Ella was wakeboarding behind a 42-foot 2017 Hanse Fjord yacht near a sandbar at the same time as another unidentified female on a wake surfboard rode, officers wrote in the report.

Ella and the other female being towed fell into the water at different times and locations.

While waiting to be recovered by her boat, another vessel struck her and fled the scene, officials said. A witness said the boat did not appear to swerve or slow down when it hit the girl.

Ella, who wore a life jacket, died from her injuries.

Who is Carlos Guillermo Alonso?

Alonso is 78 and lives in Coral Gables. The city is about 5 miles from downtown Miami. According to his attorney, Lauren Krasnoff, her client goes by the name Bill.

Investigators said it was unclear if Alonso knew Ella was hit or whether alcohol was a factor.

In a statement shared by Local10.com, Krasnoff said Alonso does not drink.

"Bill, who has been boating for 50 years and is a very experienced boater who knows these waters, was out boating by himself on Saturday," Krasnoff wrote in the statement. "He has no knowledge whatsoever of having been involved in this accident. If he hit Ella that day, he certainly did not know it. Had Bill thought he hit anything, he absolutely would have stopped. But he did not at any point think that he had hit anything, let alone a person."

"He docked his boat in plain sight right behind his house, and did not even know there was an accident on the water that day until officers showed up at his door," Krasnoff wrote.

USA TODAY has reached out to Krasnoff.

The FWC reported Alonso's vessel was in custody on Tuesday and Alonso was cooperating with the investigation.

Has anyone been arrested in Ella Adler's death?

Officials did not say whether Alonso was facing charges in connection to the fatal hit-and-run.

They also did not say what day they located the suspect vessel.

Who was Ella Adler?

Ella, a ballerina, lived in Miami Beach, officials said, and attended Ransom Everglades High School in Miami.

"She was a force of nature, and when she was near, everyone felt a gravitational pull toward her," her obituary reads. "She loved to dance, she loved her friends, and most of all she loved her family."

She is the granddaughter of Michael Adler, the current U.S. Ambassador to Belgium, according to the Miami Herald.

She is survived by her parents, Amanda and Matthew Adler, and her younger siblings Jaden and Adalynn, and many other relatives.
