Westchester County Criminal Attorney

Simply because you have been charged with a crime does not mean that you are guilty of anything, and an arrest on criminal charges does not equate to an automatic conviction on those charges. Our Westchester County Criminal Attorneys have had a number of clients for over twenty years that have been charged with offenses they did not commit, or overcharged, in which whatever conduct they are being charged with committing does not constitute the level of offense they are responsible for. For example, there have been cases where people are charged in felony assault cases and the evidence shows that someone else was responsible for the assault or the conduct is nothing more than the violation of disorderly conduct. At the Law Office of Mark A. Siesel in White Plains, Westchester County New York, our defense lawyers have extensive experience in defending clients charged with a variety of crimes and protecting their constitutional rights.

When we represent clients in criminal cases, we scrutinize carefully every aspect and element of the case, from whether the arresting officer had probable cause to enter the premises, for example, whether Miranda warnings were given, whether evidence was collected properly or was subject to contamination, whether there is a problem with the chain of custody of any evidence, whether the client was properly afforded the right to a speak to an attorney immediately upon request, whether any statements were given voluntarily, whether the client was properly identified by any alleged witnesses, and whether alibi information was considered prior to the charges, to name a few examples.

Criminal Defense Advocacy for Our Clients Facing Serious Charges

At our law firm, we have defended clients charged with crimes that involve the following, to name a few examples:

  • Drug crimes (possession or trafficking)
  • Assaults
  • Vehicular crimes (aggravated unlicensed operation)
  • Property damage (including tire slashing)
  • Patronizing a prostitute
  • Petty larceny
  • Forgery
  • Prescription tampering
  • Obstruction of governmental administration

Representing Clients Charged With Misdemeanors and Felonies

At the Law Office of Mark A. Siesel, we are detailed and relentless in reviewing the procedures that led to an arrest and the evidence against our client. We identify whether law enforcement violated your constitutional rights in any way, and litigate through trial those cases which cannot be resolved through an effective, sensible and expeditious plea bargain.

Long-Term Effects of a Criminal Conviction

Our criminal defense attorneys offer the experience, knowledge and diligence to reduce the potential impact of any criminal conviction if the evidence does not support taking your case to trial. A criminal conviction on your record can have long term effects, particularly on employment prospects. You must note the conviction on any job applications, hindering your ability to advance in your career. You require the representation of seasoned litigators, which is what the Law Office of Mark A. Siesel provides.
