A 41-year-old Kansas City police detective has pleaded not guilty in the death of a Black man who was killed last year while sitting in his truck.

Eric DeValkenaere is charged with first-degree involuntary manslaughter and armed criminal action in the Dec. 3 shooting death of 26-year-old Cameron Lamb.

DeValkenaere, who has been suspended from the police force, pleaded not guilty Tuesday. Court records say DeValkenaere was one of two officers who went into Lamb's backyard while investigating an earlier disturbance.

DeValkenaere told investigators he shot Lamb after he saw him reach for a gun and aim it at the second officer.
