Facing Criminal Prosecution is Frightening. Finding a strong advocate is critical to a successful outcome. John J. McMahon has been fighting for his clients since 1990. Experience has demonstrated that an aggressive challenge to the prosecution’s case must be mounted immediately. The Law Office of John J. McMahon will bring all necessary resources to bear to immediately investigate the charges.

Failure to act quickly can jeopardize an otherwise valid defense. Favorable video surveillance must be located and preserved before it is discarded or destroyed. Witnesses must be interviewed while their memories are still fresh. Scene photos/videos must be taken while the area in question remains unchanged. A vigorous investigation must be followed up with an aggressive motion practice. Failure to challenge the admissibility of the prosecution’s evidence will not only be detrimental to a favorable result at trial but will also risk any chance at relief on appeal.

John McMahon has experience in litigating all forms of pretrial motions.  When appropriate he has sought and obtained interlocutory relief from both the New Jersey Appellate Division and The New Jersey Supreme Court.  Criminal trials in today’s courtrooms frequently depend on expert testimony.  The Law Office of John J. McMahon is ready to engage the experts needed in mounting a strong defense. Whether pathologists, accountants, scientists, engineers or other forensic specialists, whoever is required will be engaged. In challenging the prosecution’s experts, John McMahon brings almost three decades worth of experience to bear in cross-examination skills.  Finally, if trial is required, few lawyers have successfully tried as many complex cases as John McMahon.
