Jordan Lindsey, a 21-year-old Loyola-Marymount University student from Torrance, California, was killed in a shark attack in the Bahamas in June.
In an exclusive interview airing Wednesday on "Good Morning America," her family members discuss how they've begun to cope with her tragic loss.
It was on the third day of a family vacation when they decided to take a last-minute excursion through the Sandy Toes Tour Company to Rose Island -- a spot famous for snorkeling and for petting swimming pigs.
"I wish they didn't let us on, of course, but they -- they snuck us on," Jordan's father, Michael Lindsey, told "GMA."
"Myself, my two boys, and Jordan's girlfriend, Gianna, were on another part of the island, just swimming on the beach side," he recalled. "My wife, Kami, and Jordan went snorkeling on another part of the island. My wife was near Jordan, a few feet away."
It was then that a school of sharks suddenly pounced on Jordan.
"Kami said she heard Jordan yell like, 'Mom,' like, and then she -- Kami -- looked back, and the first thing was, she thought dolphins were around Jordan," Lindsey continued. "And then she ... then she realized, like, right away that, like, Jordan, was screaming."
Kami swam toward Jordan as fast as she could.
Jordan's right arm was torn off in the attack, and she suffered bites to her left arm, both legs and buttocks, authorities said.
Kami attempted to pull Jordan to safety, but then another shark attacked her.
"And then," Lindsey said, "Jordan said, 'Mom, there's another shark coming!' And then the second shark hit her. The second shark hit again, like, on her lower leg. And then that's the last thing … Jordan said."

Jordan was losing consciousness, barely clinging to life, when the boat finally arrived -- with no medical supplies.
"They put towels over her leg … there was no first aid kit," her father told "GMA."
The boat rushed Jordan to a dock where an ambulance was waiting for her, but by the time Lindsey got the hospital, he was too late.
"I walked in," he recalled, "and they said, 'Your daughter's gone.'"
The family hasn't been the same since Jordan's tragic death.
"Kami, of course, had the worst, like, 10 times the worst thing," Lindsey continued. "She has her daughter die in her arms on a trip. I mean, we cry every night still. And -- Kami has -- like, she doesn't like the nights. Because … when she closes her eyes, she's back in that water again. She's seen all the blood. She seen her poor daughter die in her arms."
Jordan's girlfriend, Gianna Gabrielle-Kasparek, who was with the Lindsey family at the time, said Jordan "had the biggest heart."
"She cared a lot about me and her family," she added. "She'd always worry about all of us. And she probably worried about us more than she worried about herself."
Sandy Toes Tour Company extended condolences and prayers for Jordan and her family after her death and reportedly added new safety measures including shark spotters on tours.
"All reasonable steps were taken to prevent this very unfortunate incident and our staff responded swiftly and in line with our emergency protocols and procedure," the company said in a statement.
The Lindsey family wants to prevent what happened to Jordan from happening to anyone else.

From the captain all the way down to the deck hands. Everyone should know … what to do in case there is some kind of big tragedy like that … and then have the supplies to stop bleeding or if someone has a heart attack."
Lindsey went on to describe his daughter as his "little guardian angel."
"She took care of me," he said. "I just ... I remember kissing her on the forehead, and that's the last time I seen her. I just kissed her on the forehead and said, 'I'll -- I'll see you later, Jordan.'"
