The Columbia police, fire and EMS departments responded along with the Monroe County Sheriff’s Department shortly before 5:10 p.m. Tuesday for a crash involving a car and motorcycle in the 500 block of D Road in Columbia.

Traffic was closed from the crash site on D Road to Valmeyer Road, with vehicles diverted to Bluff Road while crews worked to clear the scene.

Police said a Baodiao motorcycle driven by Adam L. Griest, 19, of Columbia, was traveling south on D Road just south of Valmeyer Road with a witness traveling directly in front of the bike. A 2021 Honda Pilot driven by Luis P. Palma De Leon, 48, of Columbia, was traveling north on D Road with two passengers.

A witness told police that the motorcycle veered into the Honda’s lane of travel, resulting in a head-on collision that ejected Griest from his bike.

Griest was transported to Mercy Hospital South in St. Louis County for treatment of serious lower body injuries. No other occupants required medical transport.
