Attorney John J. Gilsenan represented the defendant in a Rochester criminal defense case involving serious felony drug and firearm allegations that ended with prosecutors dismissing the charges against his client. The prosecution arose from a December 2025 search of a Rochester residence that investigators claimed contained approximately 287 grams of suspected cocaine and several firearms. The client faced a first-degree criminal possession of a controlled substance charge, multiple second-degree criminal possession of a weapon charges, and related allegations under New York law.

The allegations carried potentially length prison sentences. Criminal possession of a controlled substance in the first degree is a class A-I felony in New York, while criminal possession of a weapon in the second degree is a class C violent felony. After conducting an extensive defense investigation, Gilsenan ultimately convinced the Monroe County District Attorney’s Office to dismiss the case against his client. The dismissal underscores the importance of early and extensive investigation in any Rochester drug possession and gun possession prosecution.

Attorney John J. Gilsenan has a track record of success defending clients facing serious gun and drug charges in both New York and federal courts. For over a decade, individuals facing felony drug charges or firearm offenses in Rochester, Monroe County, Ontario County, Wayne County, and in the U.S. District Court for the Western District of New York have trusted John J. Gilsenan’s knowledge and experience to handle their case. 

An arrest or criminal complaint is not a conviction, and every case turns on its own facts. This dismissal represents a favorable outcome for the client but does not guarantee a similar result in any other matter.
