DALTON TOWNSHIP, Mich. (WZZM) -- A mother whose son died in a drunk driving crash says she wants other teenagers to choose differently.

On the night of December 12, 2007, Chad Neiger-Bickham turned into the path of a tanker truck on M-120 and Old Orchard Road in Dalton Township.

He had been drinking at a party before the crash, which killed his step-brother, Shawn Huq, 16, and two friends -- Aaron Pham, 16, and Terry Ripley, 19.

On Wednesday night, the victims' loved ones gathered at the same intersection where the accident happened for a candelight vigil. They held a moment of silence to reflect on the teenagers' lives.

"It's not something you get over," says Jayne Bickham, Shawn Huq's mother and Niger-Bickham's step-mother. "You get through, you do the best that you can, but you're always always missing your child. It doesn't matter. You still always have that empty spot.

"You can't bring them back. I just want kids to be safe and be smart."

Chad Neiger-Bickham is spending seven to 15 years in prison for the crash.

Jayne Bickham says she cannot talk to her step-son yet, but she's sent him a letter encouraging him to share his lesson with children once his sentence is finished.
