Kaliegh Nicole Ottis, 19, an Alpha Delta Pi sorority member and Lake Mary High School graduate, was a passenger in a 2003 Dodge Durango that overturned and hit a tree at 10:50 p.m. in Suwannee County, the FHP report said.
"She was always helping people," said Kaliegh's sister, Kelsey Ottis. "She was a smart, happy person."
The driver — Sarah Bogdon, 19 — told FHP they were traveling west in the left lane when she thought the vehicle in the right lane had "slightly swerved" toward her vehicle, an FHP report said.
Bogdon swerved the SUV to the left and lost control, FHP said.
The sport-utility vehicle left the roadway, rolled over and hit a large oak tree.
"Kaliegh was going for moral support," her sister said. "She just wanted to be there for Sarah."
"We were so deeply saddened to hear of this tragic accident. Our hearts and prayers go out to the sisters, friends and family grieving over the loss of Kaliegh Nicole Ottis," said Alpha Delta Pi International President Tammie S. Pinkston.
Ottis first enrolled at UCF in the summer of 2012 and was an interpersonal-organizational communication major.
"Our UCF family's thoughts and deepest sympathies are with Kaliegh's family, friends and sorority sisters," said Chad Binette, UCF spokesman.
The family is scheduling funeral arrangements for next week.
"It is just so hard on us right now," Ottis' grandmother told the Sentinel.
Bogdon had minor injuries and is resting at her family home in Lake Mary, Ottis said.
The crash is currently under investigation.
