Lonnie Was Riding His Bike Through a Residential Neighborhood

Lonnie was riding his bike through a residential neighborhood. He failed to stop for a stop sign and barely avoided a collision with a car. Officer Mertz stopped Lonnie with the intent to warn him that he had violated a section in the Vehicle Code that applies to bicyclists. Once Officer Mertz got out of her car, she smelled a strong odor of marijuana. She asked Lonnie if he had been smoking marijuana. He said yes. She ordered Lonnie to put his hands on the patrol car and patted him down. She found a switchblade knife in his pants pocket. After she found the switchblade, she arrested him and did a thorough search of Lonnie and his fanny pack. She found a bag containing approximately 50 grams of cocaine in the fanny pack.
