Felony Assault Charges

Whereas many assaults are considered misdemeanors, serious assaults may be charged as felonies, such as:

  • Assault with a deadly weapon
  • Sexual assault
  • Aggravated assault
  • Domestic assault on a spouse that results in severe injuries or death

We hold the government to the requirement that it must prove that the alleged attack occurred and hold the prosecution to its duty of proving each and every element of the crime beyond a reasonable doubt. Whenever charges cannot be dismissed pretrial possible, our Tucson violent crime attorneys seek to have charges reduced to misdemeanors to avoid felony convictions.

Experience Representing Defendants Who Face Life and Death Sentences

Our defense lawyers have experience representing defendants facing the most severe sentences possible - life in prison and the death penalty. Our Tucson violent crime and homicide attorney Joseph P. St. Louis has been designated as Learned Counsel – allowing him to serve as lead counsel in federal death penalty cases.

Joe has successfully argued for life sentences sparing defendants the death sentence in the Arizona and U.S. Federal Court criminal justice systems. He persuaded judges in two back-to-back first-degree murder cases to dismiss all murder charges during the trials.

Up-to-Date Knowledge About Forensic Evidence

Law enforcement relies on the following to solve serious crimes:

  • Fingerprinting
  • DNA analysis
  • Computer forensics
  • Blood splatter testing
  • Teeth mark assessments
  • Blood testing
  • Ballistics

However, the results of complex forensic tests are often far less accurate and reliable than the prosecution purports. Mistakes in the collection, storage, and analysis of evidence can result in incorrect conclusions that put innocent people away and allow the guilty to go free. Yet because the evidence is based on scientific methods, jurors are likely to blindly accept forensic evidence as proof.
