Mario Brassell was taken to University of Michigan Hospital. He suffered a broken nose. His front teeth were shattered and his gums were pushed back.
But he survived the 30-foot fall and was back home Wednesday night playing with his little brother. Now, his mother wants to know what happened that morning at school.
Brassell is a special needs student with Down syndrome. He was on the school gym's running track while in a fitness class. His mother, Kimberly Brassell, got the call from Mario's teacher.
"I said, 'What happened?' She said he fell. She didn't know what happened because none of the adults were in there at the time. The children were there at the track," Kimberly Brassell said.
Her son was clearly injured. An ambulance rushed him to the hospital.
Brassell believes there was a lack of supervision and the accident could have been prevent. School leaders are trying to get to the bottom of how and why Mario fell.
"The school superintendent says there will be an investigation," she said. "They will inform me after the investigation is done. He said they have some witnesses and they have to read over their statements to see exactly what happened."
While his mother and the school work to find out why he was injured on Monday, none of it is phasing young Mario. He is in some pain, but has been a good sport. Playing with his little brother still makes him smile.
"You trust who you leave your child with," Brassell said. "I thought I had left my child in great hands. I mean, he fell 30 feet. It's by the grace of God that Mario is still alive."
