Zsófia fájdalomtól ébredt. Valami fontos álom kergette, de a hirtelen hasi görcs elvitte az emlékét. Soha nem fájt még így a hasa, még a háta is belefájdult.
Lassan felült az ágyon, de amint megpróbált felállni, úgy érezte, mintha késsel szúrták volna keresztül. Felsikoltott, és a földre gördült. Térdelve ért el a komódhoz, ahol a telefont töltőre tette. Így hívta a mentőket – térdelve, egy kézzel a földet támasztva. „Nyugodj meg, hamar itt lesznek” – próbálta magát megnyugtatni. – „De ajtót kell nyitni!” Térdelve mászott a hall felé, a hasa lüktetett, mintha tűz égett volna benne.
Megpróbált kiegyenesedni, hogy kinyissa a reteszt, de a fájdalom újra megszúrta. Szeméből kicsordult a könny. Ez az, ami félelmetes az egyedüllétben. Nem az, hogy nincs, aki vizet hozzon, hanem az, hogy nincs, aki ajtót nyisson a segítség előtt. Ajkát harapdálva megpróbált még egyszer. Kinyitotta az ajtót, és elvesztette az eszméletét.
Álmos ködben hallott töredékeket: kérdések, válaszok. Vagy csak úgy tűnt.
A kórházi ágyban ébredt, az ablakon át az őszi nap vakított. Megrántotta magát, elfordult a fénytől, és rögtön elvágódott a mellkasa alatti fájdalomtól. A hasa duzzadt volt, de alig fájt.

# Introduction to Forensic Science
### View More
In this course, you will assume the role of a forensic scientist to analyze different types of evidence found at crime scenes, including fingerprints, hair, fibers, documents, ballistics, and human remains. In addition, mock crime scenes will test your observation skills. Finally, you will study the various careers available to forensic scientists and how they work alongside law enforcement officials to help keep us all safe.
Units
Observation Skills
Observation is a very important part of forensic science. Investigators must be able to observe, interpret, and report observations clearly. In this unit, you will learn how to observe what may appear to be insignificant details at a crime scene—things that most people generally overlook. You will also learn how to distinguish between facts and opinions and how forensic scientists must remain unbiased in their observations.
Crime Scene Investigation and Evidence Collection
Crime scenes tell a story. The position of evidence, bodies, and the overall condition of the crime scene provide important clues that can help investigators determine what took place. In this unit, you will learn about different types of evidence, crime scene searches, and the proper way to collect and package evidence to maintain the chain of custody.
The Study of Hair
Hair is considered class evidence. Alone (without the follicle) it is not possible to identify an individual by hair, but hair can be used to corroborate (support) other evidence found at a crime scene. In this unit, you will learn about the different parts of hair and how to distinguish between human and animal hair. You will also learn about different types of microscopes that forensic scientists use to examine hair and other trace evidence.
A Study of Fibers and Textiles
Fibers are another example of trace evidence. Fibers may be transferred from a victim to a suspect, from a suspect to a victim, or either way between a suspect or victim and the crime scene. In this unit, you will learn about the different types of fibers and fabrics, along with the different types of tests that forensic scientists use to examine them.
Forensic Botany
Due to the immobility of plants, botanical materials found on a suspect or victim can be used to place the individual at a crime scene. In this unit, you will learn about plant anatomy and how forensic botanists examine plant materials in order to aid in criminal investigations.
Death: Meaning, Manner, Mechanism, Cause, and Time
To determine how or why a person died, forensic pathologists perform autopsies. In this unit, you will learn how to determine manner, cause, and mechanism of death, as well as how to approximate the time of death by evaluating rigor mortis, livor mortis, and other factors. You will also learn how forensic entomology can be used to aid in investigations of death.
Forensic Anthropology: What We Learn from Bones
Forensic anthropologists use bones to determine the identity of a victim as well as his or her life history, cause of death, or other clues about a crime. In this unit, you will learn about the bones of the human skeleton and how to tell if bones are male or female. You will also learn how bones can reveal a person’s age, stature, and ethnicity.
Forensic Entomology
Forensic entomologists use the study of insects to aid in legal investigations. In this unit, you will learn about the life cycle of insects and the stages of decomposition. You will also learn how forensic entomologists collect insect evidence from a crime scene.
Fingerprints
Fingerprints are a commonly used tool in forensic science. The ridge patterns on the skin of human fingers are unique to each individual and do not change over time. In this unit, you will learn how fingerprints are formed and about the different types of fingerprint patterns. You will also learn how latent (hidden) fingerprints are collected at crime scenes.
DNA Fingerprinting
DNA fingerprinting is a powerful tool used in forensic investigations. DNA found at crime scenes can be linked to suspects or can be used to exonerate those who have been wrongly accused or convicted of crimes. In this unit, you will learn about the structure of DNA and how biological evidence is collected, preserved, and analyzed.
Handwriting Analysis, Forgery, and Counterfeiting
Handwriting is a skill that takes years to develop. Each person’s handwriting has unique characteristics that can be used to identify the writer. In this unit, you will learn about different types of handwriting samples and how to analyze them. You will also learn about forgery, counterfeiting, and fraudulent documents.
Forensic Toxicology
Forensic toxicology is the study of poisons or drugs and their effect on the human body. In this unit, you will learn how toxicologists detect and identify drugs and poisons in body fluids, tissues, and organs. You will also learn how alcohol is absorbed, metabolized, and excreted by the human body.
Ballistics: Firearms and Tool Marks
Firearms evidence can be useful in linking a suspect to a crime. Fired bullets and spent cartridge casings found at crime scenes can be matched to suspect weapons through microscopic examination. In this unit, you will learn about different types of firearms, ammunition, and firearm injuries. You will also learn how test fires are conducted in order to match bullet and cartridge evidence to a particular firearm.
Final Exam and Course Project
In this unit, you will review the concepts that you learned throughout the course and take the final exam. You will also have the opportunity to report on the mock crime scene that you analyzed in the beginning of the course.
