Expert Legal Testimony Can Be Given By A Forensic Neuropsychologist In Los Angeles

By Marci Glover


An accused murderer may be either convicted or exonerated with the help of forensic evidence. Some witnesses are adept liars and a jury member may believe the lies. However, when confronted with the concrete evidence provided by DNA, the facts confirmed by a forensic neuropsychologist in Los Angeles are indisputable.

The trained scientist can take samples of blood, semen and other bodily fluids to match them to the victim and the defendant. The facts provided by blood evidence cannot be denied and they are always available. A car can leave tire tracks in the mud where someone leaves a body and these can be matched to the vehicle. Footprints can be matched to a pair of shoes.

There may be many such shoes in the same size worn by many people. However, each person has an individualized wear pattern and the sole will reveal that if compared to another pair owned and worn by the suspect. The same is often true of tires.

Some plant life or other residue can be left on the undercarriage of a car. Perhaps it is something that only grows in a few places. If what is trapped under the car can be matched to the place where a body was dumped, that will indicate the guilt of the automobile owner.

The police can get a search warrant for a car if there is a good reason to suspect the owner. The interior and the trunk may have blood evidence. Blood can always be detected by using a substance called Luminol. When sprayed on a surface it illuminates the blood evidence.

Blood might be typed and proven to match the victim. If there are pet hairs on the victim, those can be transferred into the car and matched to the pet owned by the victim. A bullet is another clue. It will match the gun it was fired from. If the owner of the car also owns the gun, he is implicated in the murder.

Blood type can be identified when it is extracted from the bone marrow of a skeleton. The skeleton can indicate age, gender and ethnicity of the victim. Any dental work or surgical repair to a broken bone can help to identify the victim when matched to known records.

A neuropsychologist is able to analyze brain damage and how it affects behavior. A brain scan will show which area of the brain is damaged. This can show whether or not a suspect is legally competent to participate in his or her own defense. This valuable evidence may relieve a suspect of responsibility for abberent behavior.

Services include giving testimony, putting together neuropsychological evaluations, doing reviews of existing cases, doing medical evaluations and consulting with attorneys as a case is put together. The brain animation gives a clear idea of what happened to affect an individuals behavior. Non-scientists such as the judge and jury can understand such a pictorial representation of the genetic defect or injury by seeing the animation.

It labels the areas in the brain responsible for speech, memory and other functions. Seeing any abnormalities helps the jury, the judge and those in the courtroom to comprehend the facts. A picture can certainly be worth a thousand words.
