Experts, DNA, Fingerprints, and Trace Evidence

No attorney in the country understands the world of forensic science better than Attorney Patrick O’Keefe.  Attorney O’Keefe has received years of training from the Michigan State Police, FBI, and Secret Service on forensic evidence analysis. Forensic testing can impact–positively or negatively–the criminal investigative and prosecutorial process.  With the evolution of powerful advancements in forensic science, many criminal cases involve expert witnesses. In a sexual assault case, the prosecution may call multiple experts, ranging from a SANE (Sexual Assault Nurse Examiner) nurse, a physician expert in sexual trauma, and a DNA expert. In a homicide or home invasion case, there may be an expert in Trace Evidence (e.g., hairs, fibers, tool marks, glass, footwear impressions), Forensic Pathology (cause and manner of death), and/or DNA analysis.

Perhaps through the assistance of fictional crime shows, the common misconception is that the police find DNA samples in abundance. In fact, the discovery of DNA “matches” is quite rare.  People also falsely assume the testing process is fast. It is not. The process can take months, sometimes years. You should be careful to do your homework before accepting the findings of the police or the prosecution’s expert. In some cases, their work may not be 100% accurate. You should also be careful not to assume that the police have found an adequate DNA sample at the crime scene.  They may be bluffing when they tell you they have your DNA.  There are no laws which prohibit a police officer from bluffing a suspect in order to get him/her to make an admission or confession. Therefore, you should be careful to consult with an experienced attorney BEFORE you are charged with a crime.  Attorney Patrick O’Keefe has numerous instances when he was able to AVOID criminal charges from being issued against the accused by negotiating with the police and prosecution.

Attorney Patrick O’Keefe has handled countless cases involving forensic analysis, and has interviewed and examined experts from many disciplines: DNA, Serology, Toolmarks, Fingerprints, Latent Prints, Blood Alcohol Analysis, Firearms, Video Analysis, Pathology, Toxicology, Sexual Trauma, Forensic Anthropology, Domestic Battery Profile, Drug Profile, and the list goes on. Many cases are won and lost because of the forensic science involved. Therefore, your attorney’s mastery of these areas can—and will— make all the difference in your case.

Mr. O’Keefe has received training in the following areas:

  • DNA Analysis
  • Forensic Interviewing Protocol (Protocol established by the State of Michigan in sexual assault investigations involving children)
  • White Collar Crimes and Counterfeiting
  • DUI Investigation and Toxicology
  • Datamaster (Breathalyzer) Operation
  • Drug Profile Evidence
  • Domestic Assault Profile Evidence – Batterer and Victim Profile evidence

With the evolution of powerful advancement of forensic science, many criminal cases involve the assistance of expert witnesses. In a sexual assault case, the prosecution may call multiple experts, ranging from a SANE (Sexual Assault Nurse Examiner) nurse, a medical expert in sexual trauma, and even a DNA expert. In a homicide or home invasion case, there may be an expert in Trace Evidence (e.g., hairs, fibers, tool marks, glass, footwear impressions), Forensic Pathology (cause and manner of death), and/or DNA analysis.

Perhaps through the assistance of fictional crime shows, the common misconception is that the police find DNA samples in abundance. People also falsely assume the testing process is fast. It is not. However, because the most common DNA samples come from blood, semen and saliva, and often comes in a mixture with other substances, the process can take months, if not years. You should be careful to do your homework before accepting the findings of the police or the prosecution’s expert. In some cases, their work may not be 100% accurate. Furthermore, you should be careful to consult with an experienced attorney before taking the officer’s word for it. The police officer may even try to trick you into thinking your DNA was on a weapon or at the crime scene, just minutes or hours after the alleged crime occurred. If that sounds ridiculous, it is. This is not CSI on television. Nothing gets done that quickly.

It is paramount that you consult with an experienced criminal defense attorney before venturing into this rocky terrain.
