Six families have been forced to live without their child after a bus crash killed their children. One week later, they're still at a loss to answer the question, why?

Five children remain in the hospital as of Monday afternoon. Three of those five children are in critical condition.

As family and friends hold funerals this week, we're also learning more about their impact the children on their lives.

Zoie Nash

She could barely walk on her own, but Misti Nash took every ounce of energy she had to visit a memorial built for her daughter Zoie and the five other lives taken on Tally Road in Chattanooga.

"For her to lose a child, it's heartbreaking. She's trying to be strong," said Antwon McClain, Zoie's uncle.

McClain said Zoie was talented, especially when it came to softball, her favorite hobby.

When her family buries her this Thursday, they're asking everyone to wear her team's colors: purple, black and grey. Colors you could often find her in.

Cor'Dayja Jones

Hundreds attended the funeral for Cor'dayja Jones Saturday. The nine-year-old always posed for the camera showing her personality.

She sang in her church choir and helped set up for worship each week. Her family said she loved being a big sister.

Zyaira Mateen

At only six-years-old, Zyaira Mateen already had big goals. Her family says she wanted to be a doctor.

"None of them kids deserved that. None of them. My baby had a whole life ahead of her. She was so full of life," said Jasmine Mateen, Zyaira's mother.

The Chattanooga Times Free Press reported that she had a sibling just nine months apart and they acted like twins. They were side-by-side when the bus hit the tree last week. Her sister survived.

Zyanna Harris

Zyanna Harris, 10, lived to dance. Her family says she was always active and only sat down when she watched Tyler Perry and Lifetime movies.

"Funny" and "sassy" are words they use to describe her.

D'Myunn Brown

Kindergartner D'Myunn Brown loved to learn and loved to go to school. He was his mother's only child.

"I didn't wake up thinking I was going to lose him. I would never put him on the bus," Diamond Brown, D'Myunn's mother, said.

Keontae Wilson

Keontae Wilson, 8, enjoyed football and was tough.

He died in the hospital two days after the crash.

The Chattanooga Times Free Press interviewed Woodmore Elementary fifth-grade teacher Tanya Victor who ran into Keontae as he loaded the bus.

"He ended his school day in a good mood, with the brightest smile I'd ever seen on him," she told the Times Free Press. "I will never forget the details of those moments. I'll never forget the shirt he was wearing. I'll never forget him."
