Prosecutors pulled the plug on the trial of Messiah Booker, 32, in the midst of a hearing in which defense attorney Brendan Ahern of Hauppauge was methodically detailing dozens of instances of evidence withheld by Assistant District Attorney Glenn Kurtzrock.

"Craig McElwee, president of the Suffolk County Criminal Bar Association, said any lawyer who doesn't do what Ahern did — meticulously examining the file to figure out notes were missing and then making a strong argument about the misbehavior — is failing his or her client and the criminal justice system."

Mr. Ahern was retained to represent the limousine driver, criminally charged with tragically causing the death of four young women and injuring several others during a crash near the North Fork wineries in the Summer of 2015. On the date of his client's arraignment, Mr. Ahern stated, "Criminal liability is not always measured by the depth of human tragedy…the lines between civil liability and criminal liability have been blurred in this case."

Since that date, Mr. Ahern has challenged the sufficiency of the evidence presented to the grand jury and is determined to vindicate his client for the wrongful criminal charges brought against him. Mr. Ahern is determined to demonstrate that criminal charges in this case are misplaced and prohibited by the controlling law of the state.

Relying upon his expertise in the area of Accident Investigation and Reconstruction, Mr. Ahern has both the legal and scientific training to critically scrutinize the evidence, and advance powerful arguments in support of dismissal of the homicide and other criminal charges.

Stay tuned for the legal determination.
