HOLLAND, Mich. (WOOD) — The family of Johnathan Herlein hopes the driver investigators are still looking for will help them understand his tragic death.

Herlein was riding his bicycle to work early Wednesday morning when he was hit on Waverly Road near 32nd Street in Holland. That driver stopped in the road to call 911; however, investigators say a second driver who ran over the 20-year-old never slowed down or stopped.

“It could’ve been an accident. It could’ve been more than that. We never really know until someone says something,” his younger sister Rheeni Will told 24 Hour News 8 Friday.

Not knowing who the driver is or why they didn’t stop is adding to the pain they’re suffering.

“You can accept it if it truly was just not paying attention and in a hurry and going to be late for work. You can accept that, but you can’t accept it if there was (sic) other factors involved,” Johnathan’s father, Steve Herlein explained.
