What was supposed to be a graduation celebration turned tragic for University of Miami musical theater major Elizabeth Goldenberg.

The 22-year-old, who was better known as “Ellie,” had just graduated Friday morning, according to UM, and was tragically killed in an airboat ride Saturday.

A private memorial celebration was held Monday afternoon in Ellie’s honor in the same theater where she performed so many times.

Video posted on Facebook in February of last year shows Ellie promoting one of the many musicals and plays she performed in at the Jerry Herman Ring Theater.

Ellie, originally from Pennsylvania, graduated summa cum laude with a BFA degree.

She was also this year’s recipient of the Friends of Theatre Award, “one of the highest honors bestowed by the Department of Theatre Arts in acknowledgement of her incredible talent and unlimited potential in acting,” according to UM.

Florida Fish and Wildlife Conservation Commission said Ellie was aboard an airboat ride Saturday with her parents and younger sister when they were ejected.

Ellie died from her injuries.

UM released an email saying Ellie was loved by her faculty, fellow students and friends.

According to UM, Ellie’s funeral will be held Tuesday in Pennsylvania.
