A 19-year-old man from Colorado Springs died after the car he was riding in collided with a semi-truck Monday.

Police said the semi-truck had pulled over just north of the Bijou Street exit because of mechanical problems.

A red sedan driven by Dezirae Shier-Gill, 19, drifted onto the shoulder of the road and collided with the left side of the semi-truck, police said.

Detectives believe Shier-Gill was talking with her boyfriend, Wade Lehman, and became distracted.

The collision killed Lehman, police said. Dezirae Shier-Gill, was taken to a local hospital with non-life-threatening injuries.

The driver of the semi-truck, Lawrence Molina, 48, from Corning Calif., was not injured.

Police said I-25 was closed from noon until 2:40 p.m. while police investigated the collision.

Shier-Gill was served a traffic summons for misdemeanor careless driving resulting in death.
