The three Georgia high school students killed in a Florida crash during spring break have been identified by officials.

The Franklin County Sheriff’s Office said the collision occurred on Monday, April 6, when four teens were traveling to St. George Island to visit family and friends while on break from school.

“Three of the teens tragically lost their lives, while one teen was transported by Survival Flight to a hospital for treatment,” the sheriff’s office said.

The crash occurred after their vehicle ran off a shoulder, struck a tree and caught fire, according to local affiliate WANF, citing Florida Highway Patrol.

The three teens who died, all students at Horizon Christian Academy, have since been identified as Jackson Mobley, 18, Jaylyn Fehr, 17,  and Charlotte Martin, 16.

The fourth person in the car, Jamison Mobley, 17 — Jackson’s sister — was rescued from the wreck and is continuing to recover, according to authorities.

“Jackson, Jaylyn, and Charlotte were wonderful young individuals and students who were deeply loved by their families, friends, classmates, teammates, teachers, church communities, and everyone who knew them,” the sheriff’s office said in a statement. “They were talented athletes, exceptional students, and, above all, kind-hearted individuals whose lives touched many.”

According to a video statement, Franklin County Sheriff AJ Tony Smith said that officials didn’t know “how fast they were going or what happened.”

PEOPLE contacted the Florida Highway Patrol on Thursday, April 9, but did not receive additional information.

In a social media post Wednesday, Horizon Christian Academy called Jackson a “gentle giant, an incredible brother, had the best one-liners, and was a dream son.”

“The void Jack will leave behind is insurmountable,” the school said, “We know the last thing he did in his soul earthside was to help save his sister, Jamison.”

Meanwhile a GoFundMe established for the family of Jaylyn, remembered the junior as being a cherished member of Horizon’s volleyball team as well as an honor roll student who was planning to pursue a law degree upon graduation next year.

“Her faith and kindness touched everyone who knew her, and her loss is deeply felt by her family, friends, and the entire community,” read a message on the fundraising page.

Like Jaylyn, Charlotte was also a junior and volleyball player, according to a GoFundMe created for her family.

“Charlotte was like a ray of sunshine, always smiling and always friendly,” loved ones wrote, while the school added in their own tribute that, “while her achievements were many, what defined Charlotte most was her faith, her kindness, and the way she loved others.”

Horizon Christian Academy also urged the community to keep Jamison, the sole survivor of the crash, in their thoughts and prayers.

“We pray for her healing. We pray for peace and comfort for her family,” the school wrote in their statement. “We pray for wisdom and clarity for the doctors as they treat her.”

The Franklin County Sheriff’s Office said that crosses will be placed at the accident site bearing the names of Jackson, Jaylyn and Charlotte as a small memorial for them.

“Life is precious, and we would like to honor their lives and memories here in our community,” they wrote.
