Put Our Experience to Work for You
If you have been arrested for a weapons offense, you are likely facing the possibility of a lengthy jail or prison sentence. Let us put our experience to work for you. Attorney Mark A. Hammer is a former prosecutor who can provide a vigorous defense on your behalf.
Enhancement of Criminal Penalties
Whenever a person is carrying a firearm during the commission of a crime, the criminal penalties they face are enhanced. Even if no person is harmed, the commission of a crime with the use of a gun can lead to a significant period of incarceration.
If retained to handle your case, our law firm will work diligently to seek the best possible result for you. We will carefully examine the evidence, make motions to suppress any evidence seized in violation of your constitutional rights and aggressively attack the prosecution's theory of the case. We believe strongly that every person has a right to a dedicated attorney and a zealous defense.
