Off-duty police officer Jamell Dent was riding his motorcycle around 10:45 p.m. Saturday when he collided with a car, flipping onto its roof.

A couple and their infant were riding in the car. Both adults in the car are in critical condition.

The infant was rushed to the hospital, and was eventually pronounced dead.

DeKalb County police are investigating the cause of the crash.

Dent had just moved to the Lithonia Police Department after spending six years as a member of the DeKalb County Police Department.
