Global Congress on Forensic Science and Research

The Iconic Meetings cordially welcomes you to the Global Congress on Forensic Science and Research (Forensic Research-2025), taking place from November 13-15, 2025, in Valencia, Spain. This prestigious conference serves as a dynamic platform for forensic scientists, researchers, academicians, law enforcement professionals, and industry experts to engage in discussions on the latest advancements and challenges in forensic science. With a focus on innovation, collaboration, and knowledge exchange, Forensic Research-2025 will cover a diverse range of topics, including DNA Analysis, Crime Scene Investigation, Forensic Toxicology, Digital Forensics, Ballistics, Forensic Pathology, and much more. Through keynote sessions, panel discussions, and interactive workshops, attendees will have the opportunity to explore cutting-edge research, groundbreaking technologies, and practical applications in the field of forensic science. We invite young researchers, students, professionals, and industry leaders to join us in Valencia to foster meaningful collaborations, share insights, and contribute to the evolution of forensic science. Your participation will be instrumental in shaping the future of forensic research and its impact on criminal investigations and justice systems worldwide.

Delta and Core

A delta, by the technical definition is a place where two lines run side-by-side and then diverge to form a triangle.

In Image you can see where the three sides of the delta form three sides of a triangle.

Deltas help to determine the fingerprint pattern.

A core is a “dead end” formed by a ridge that loops back on itself.

----

Methods used for visualizing latent fingerprints.

Latent fingerprints are not visible, but some techniques can make them visible. Dusting surfaces such as drinking glasses, the faucets on bathroom sinks, telephones, and the like with a fine carbon powder can make a fingerprint more visible. Tape is then used to lift and preserve the fingerprint. The tape with the fingerprint is then placed on an evidence card on which the date, time, location, and collector of the print is logged. Proper evidence collection techniques involve photographing the fingerprints before they are lifted. Metal or magnetic powders can also be used. They are less messy than carbon-based powders.

Question- What is Forensic Graphology? Answer- Forensic graphology is the study of handwriting. It is also known as graphoanalysis. Graphology is a process that is used by some to attempt to determine personality traits and details about a person based off of their handwriting. Forensic investigators use handwriting pattern/technology to determine personality traits of an individual.

Question- What is Crime Scene Sketch?

Answer- A crime scene sketch is a permanent record of the size and distance relationship of the crime scene and the physical evidence within it. The sketch serves to clarify the special information present within the photo-graphs and video documentation, because the other methods do not allow the viewer to easily gauge distances and dimensions. A sketch is the most simplistic manner in which to present crime scene layout and measurements. Photographer /camera positions may be noted within a sketch also.

Question- Why is a sketch important to crime scene documentation?

Answer- ■ It accurately portrays the physical facts.

■ It relates to the sequence of events at the scene.

■ It establishes the precise location and relationship of objects and evidence at the scene.

■ It helps to create a mental picture of the scene for those not present.

■ It is a permanent record of the scene.

■ It usually is admissible in court.

■ It assists in interviewing and interrogating.

■ It assists in preparing the written investigative report.

■ It assists in presenting the case in court. Well-prepared sketches and drawings help judges, juries, witnesses, and others to visualize the crime scene.

Question-When should sketches be made?

Answer- Sketch all serious crimes and accident scenes after photographs have been taken and before anything is moved.

Sketch the entire scene, the objects, and the evidence.

Question- How many types of sketches are made of crime scene?

Answer- Two types of sketches are made with regards to crime scene documentation: 1.) Rough sketches, and 2.) Final/finished sketches.

Fracture: A fracture is a break in a bone. Fractures can range from a hairline crack in the bone to the bone being broken into two or more pieces that no longer line up correctly. A fracture may occur at the same time as other injuries, such as sprains, strains, or dislocations. Recovery time for a fracture can vary from weeks to months depending on a person’s age and health; the type, location and severity of the fracture.

Types of Fractures; Fractures have a variety of names. Below is a listing of the common types that may occur:

Greenstick - Incomplete fracture. The broken bone is not completely separated.

Transverse - The break is in a straight line across the bone.

Spiral - The break spirals around the bone; common in a twisting injury.

Oblique - Diagonal break across the bone.

Compression - The bone is crushed, causing the broken bone to be wider or flatter in appearance.

Comminuted - The break is in three or more pieces and fragments are present at the fracture site.

Segmental - The same bone is fractured in two places, so there is a “floating” segment of bone.

What Causes a Fracture? Fractures occur when there is more force applied to the bone than the bone can absorb. Bones are weakest when they are twisted. Breaks in bones can occur from falls, trauma, or as a result of a direct blow or kick to the body

Smoking and Bone Fracture: Tobacco and nicotine increase the risk of bone fractures and interfere with the healing process, according to a growing body of research. Nicotine can slow fracture healing, estrogen effectiveness, and can counter the antioxidant properties of vitamins C and E. ____________

History of Drug, Poison and Chemistry

Chemistry and forensic chemistry developed largely from ancient knowledge and techniques associated with medicines. This 4,000-year-old Sumerian clay tablet in the Museum of the University of Pennsylvania has been translated by Dr. Samuel Noah Kramer of the museum and by Dr. Martin Levey of Pennsylvania State College. The tablet contains the oldest-known medical handbook. A portion reads: “White pear tree, the flower of the ‘moon’ plant, grind into a powder, dissolve in beer, let the man drink.” (Bettmann/CORBIS/ photo dated September 27, 1953)
