WHITSETT, N.C. — Mona and William Johnson say the pain is still fresh one year after the tragic death of the son Kie.
"It's one of the hardest things of my 54 years I have ever faced," William said.
"It's so difficult,” Mona said. “It's so difficult. You're not supposed to bury your child."
Kie was killed during a car accident on August 26, 2015.
He was riding passenger side in a friend's car when officials say the car crashed head-first into a school bus.
Officials say the driver Jacob Larkin was impaired.
"Enough has not been said about impairment," Mona said.
Johnson says her son's death has inspired her to speak out against driving while impaired.
"I'm not going to solve the problem, but I want to be a part of the solution," she said.
Johnson says Tuesday's death of Kie's friend, 16-year-old Dakota French, another student at Eastern Guilford High School brought back painful memories.
Investigators with the North Carolina Highway Patrol say French was speeding when he hit a ditch and overturned several times on Sockwell Road.
“I was devastated, shocked, wanted to run over there and put my arms around the parents because I absolutely, absolutely know what they're going through," Mona said.
Johnson plans to have several speakers talk about safe driving at a commemoration service for Kie on Saturday.
It’s a message she hopes will reach everyone, especially young people.
"I won't stop,” she said. “I will not stop there. I want to go and spread this message to anyone that I can, wherever I can."
The commemoration service for Kie Johnson will be held from 5 to 8 p.m. Saturday at Springwood Park in Burlington.
