Chattanooga school bus crash: Lives just beginning …

(CNN) — A Spiderman-lover who danced to his favorite YouTube videos. A girl who dreamed of becoming a doctor. A star on the softball field.

Hours after they celebrated Thanksgiving at an elementary school lunch on Monday, their school bus swerved off the road, flipped over and slammed into a tree. Five children died at the scene. One died days later from his injuries.

The deadly crash in Chattanooga, Tennessee, left a devastated community mourning the victims and searching for answers. The bus driver is behind bars, charged with vehicular homicide. But authorities are still working to pinpoint exactly what caused the crash.

Here’s what we’ve learned so far about the six victims:

Zoie Nash: Softball star

Zoie Nash played basketball, but softball was her love.

Her uncle, Antwon McClain, described her as a “sweet, sweet girl — a little angel here on Earth.”

Zoie was just a few weeks away from her 10th birthday, he said. And her family still plans to have a party in her honor on December 12.

Her 8-year-old brother, Zachariah, suffered a broken arm and a brain injury in the bus crash, but is expected to survive, McClain said.

While he was hospitalized, his mother told him about his sister’s death, McClain said. Zoie, she told him, had received her wings.

D’Myunn Brown: Spiderman fan

D’Myunn Brown talked a lot, his mother said. He loved Spiderman.

And he loved to dance along with his favorite YouTube videos, including his latest obsession, “Juju On That Beat.”

His mother met him at the bus stop every day.

He was 6 years old.

Zyaira Mateen :’She wanted to be a doctor’

Zyaira Mateen was outgoing and full of life, her mother said. The 6-year-old’s grandmother described her as feisty, sweet and smart.

“She was the life of the party, always silly,” mother Jasmine Mateen said.

But she added that her daughter also had a serious side.

“She was real smart,” she said. “She wanted to be a doctor.”

Cor’Dayja Jones: ‘She loved God’

Nine-year-old Cor’Dayja Jones had a smile that could light up a room, family members said.

“She always smiled and she would always give you a hug and she loved being a little girl. She embodied the essence of childhood,” her cousin, LaFrederick Thirkill, told CNN.

She was in fourth grade and sang in the children’s choir at her school.

“She loved God, and she knew God,” cousin Monica Mastin told CNN affiliate WKRN. “So we know that he has another angel.”

Keonte Wilson: ‘A tough little boy’

Keonte Wilson died Wednesday, two days after the crash.

His brother, Kevin McClendon, said Keonte, who was 8 years old, was a “tough little boy.”

Zyanna Harris: She loved to dance

Zyanna Harris’ stepfather told CNN affiliate WREG that she loved to dance and had a good heart.

She was 10 years old.

Her stepfather said he’ll miss her smile.
