Chester County Criminal Cases – A Thorough Investigation is Critical

When Mr. Nenner handles criminal cases in Chester County, he focuses on a thorough investigation. It is critical to identify every piece of helpful or corroborating evidence. This includes identifying witnesses, locating helpful video footage or pictures of the scene. In one murder case, Mr. Nenner located video footage proving that his client was innocent. The footage showed Mr. Nenner’s client at an entirely different location than the murder scene, at the time of the shooting.

Latest Not Guilty Case Result: Mr. Nenner’s client was found NOT GUILTY by a jury. See Commonwealth v. Rolle, Docket No. CP-51-CR-0005699-2017. See more of Mr. Nenner’s criminal case results.

Constitutional/Legal Defenses

In Chester County criminal cases, it’s critical to review the facts and law to present any constitutional or legal challenges. When a police officer or government agent violates constitutional law, evidence critical to the prosecution’s case may be thrown out.

For example, a Chester County resident is pulled over on her way home from work for a traffic violation. The officer writes a citation and hands it to the driver. However, after issuing the citation, he continues to question the driver. Here’s the exchange:

Officer: “Ma’am, where you headed?”

Driver: “I’d like to get home. Can I leave now?”

Officer: “Do you have any drugs or contraband in the vehicle?”

Driver: “What? You gave me my ticket, already. I’m tired and want to get home.”

Officer: “Step out of the vehicle.” [The officer then searches her center console and glove box where he finds drugs and a pipe. She’s arrested for drug possession and possession of drug paraphernalia.

Here, the officer clearly had no reasonable basis to continue to ask the driver questions after he issued the traffic ticket. When he ordered her to step out of the car and searched her car, he violated constitutional law. After filing a Motion to Suppress, the drugs and pipe would be suppressed or thrown out by a Chester County judge. As a result, the charges would be dropped or dismissed.
