A teenager who died in the crash has been identified as 15-year-old Molly Wrede from Atlanta.

The US territory's emergency agency said Sunday that two friends of the girl remained hospitalized with various injuries.

It identified them as 48-year-old Scott Ellyson and his 14-year-old daughter, Casey Ellyson, of Georgia.

Twenty-two-year pilot Jose Diaz of Puerto Rico also was also injured in Saturday's crash of an Air America plane off the coast of Pinones, east of San Juan.

The plane, owned by Puerto Rico-based charter flight company Air America had just taken off from the capital's international airport on a flight to Culebra island.

The three survivors were rescued by people who were swimming or sunbathing on a nearby beach and went to the crash site in kayaks.

The accident's cause is under investigation.

Ports Authority spokesman Juan Carlos Hernandez said Wrede's body was recovered underwater.

Wrede was a student at Paideia school in Atlanta.
