Park Police officer Adam Zielinski was on patrol on the Baltimore-Washington Parkway near Route 495 just before midnight on March 30th when he saw a driver commit several traffic violations. During the ensuing traffic stop, Zielinski discovered that the driver had illegal narcotics in his possession. Zielinski removed him from the vehicle and a struggle ensued. Although the driver attempted to flee, Zielinski was able to get him handcuffed and under control. A USPP narcotics detection dog was called to the scene and alerted on narcotics in the vehicle. Officers recovered five gallon-sized ziplock bags containing about nine pounds of marijuana and a sixth ziplock bag containing about an ounce of heroine. The combined value of the drugs was placed at over $44,000. The officers also recovered more than $14,000 in U.S. currency. The driver is facing charges of assaulting a police officer, possession with intent to distribute heroin and marijuana, and driving under the influence of drugs/alcohol.
