A suburban Dallas police officer who is charged in the shooting death of a teenage burglary suspect and the wounding of another boy while off duty has resigned from his department.

Farmers Branch Police Chief Sid Fuller said that Officer Ken Johnson submitted his resignation on Thursday. Fuller accepted the resignation, which took effect immediately.

Johnson is free on $300,000 bond after being charged with murder and aggravated assault in the March 13 shootings in Addison.

Authorities say Johnson confronted the teenagers after seeing the two burglarize a vehicle at his apartment complex. After Johnson chased the two in his own vehicle, an altercation ensued, during which Johnson shot the duo.

Fuller says Farmers Branch police internal affairs investigators continue reviewing the shooting. Addison police are also continuing their investigation.
