Touch DNA

We are specialized in so-called “Touch-DNA”; minimum amounts of DNA (“low template DNA”) left when force is applied. We have over 10 years experience in finding these traces on pieces of evidence, recovering them and extracting DNA from them. Interpreting the often complex DNA profiles generated from low template DNA is an expertise in itself. Due to our experience we are better capable of performing interpretations. Read more…


3D Reconstruction

3d

3D Forensics – Forensic Measurement, Analysis and Visualization 
3D Forensic Reconstructions is a growing discipline in the field of forensics, but encompasses the use of total stations, laser scanners and photogrammetry to document crime and accident scenes in three dimensions. The resulting data can be analyzed and the environment can be reconstructed into a working model of the scene as it was at the time of the crime.

Time of death

Time of death

After a person dies there will be certain changes in the body. Because there is no heartbeat and therefore no blood flow, the blood still present in the vessels will descend under the influence of gravity to the lowest point in the body.

Biological Trace Recovery

sporenonderzoek

The research into the transfer of biological traces aims to investigate whether the traces have a relationship with a committed offence and if so what is the relationship? Except for the origin of the cells, which can be identified through a DNA-profile the determination of the relationship between the cell donor and the offence is of great significance to evidential value. This relationship can be derived from, for example, the place where the trace is discovered. In addition, the evidential value depends on the nature of the act, the action or the process in which cells are left behind. Therefore a DNA-profile that is obtained from, for example, a sampling of strangulation has more evidential value than the same profile that is obtained from a cigarette butt found at a distance from the victim.

Bloodstain pattern analysis

bpa

Bloodstainpattern analysis aims to test hypotheses that can explain some of the facts of a possible criminal offense. This takes place using the information obtained from the investigation to determine the area of origin, shape and volume of blood.

Cold cases

cold-case

Cold case refers to a crime or an accident that has not yet been solved to the full and is not the subject of a recent criminal investigation. It is possible that in some cases new information could emerge from new witness testimony, re-examined archives, retained material evidence, as well as fresh activities of the suspect.

Criminalistic Interpretation

lab2

The findings of organic (contact) traces of a person at a crime scene do not imply, in principle, anything about his or her involvement in the crime. In each case it should be determined whether the found traces are or are not “crime related”. Experts at IFS can make statements about the probability that a certain action or event occurred based on the technical findings of the case.

Cytochrome P450 Investigation

lab3

IFS comes first in examining the relationship between psychoactive medication and involuntary intoxication. In the treatment of mental disorders (such as anxiety disorders and depression) a variety of medication is used. Many of these medications and many other exterior materials are converted by enzymes of the cytochrome P450 System. A DNA polymorphism on cytochrome P450 genes can be the cause of certain medications not properly being translated.

DNA investigation

dna

DNA (Deoxiribo Nucleic Acid) is present in virtually all cells that living organisms are made of. Human DNA is in the form of various strands trapped in the nucleus of the cell. These strands of DNA are called chromosomes. The chromosomes come in pairs, one half is inherited from the mother and the other half from the father. In total, 23 human chromosomes which can be divided into 22 chromosomes.

DNA Profiling & Consultancy

profiel

There are several techniques for DNA-profiling. For forensic applications there are different, so-called “kits” available that simultaneously allow for multiple DNA characteristics to be defined. These characteristics can exist on the autosomal chromosomes as well as on the sex chromosomes. Read more…


Injury Interpretation

verwondingThere are infinitely many possibilities on which a person may have suffered an injury. Stabbing, shooting, beating, falling and self-mutilation are just some examples. IFS has researched injury interpretation for several years and is affiliated with internationally recognized experts in the field of wound interpretation. An IFS investigation can focus on questions such as the nature/distribution of injuries.

Pathology

pathologie

Pathology is the precise study and diagnosis of disease. The expertise of a IFS Pathologist is frequently requested when a case needs forensic research. A pathologist is a doctor who specialises in causes of death and thus analysis of abnormalities (like desease) of the human body. Our experience comes from working for several years in different hospital departments.

Paternity Testing

verwantschap

This research is to investigate the biological relationship between (potential) family members. It is done through DNA analysis so that a positive match will give a maximum of approximately 99.9% certainty unless it involves the paternity or maternity test. Exclusion can only happen with almost 100% certainty if it involves a paternity or maternity test, otherwise there will remain a margin of uncertainty.
