EXPLORE BY TOPIC:

Crime Scene

Crime Scene Documentation and Evidence Collection

Crime scenes must be processed following correct documentation procedures in a manner that maintains scene integrity. To do so, crime scene investigators must be able to identify the boundaries of a crime scene, secure and protect the crime scene while considering officer safety, conduct a “Walk Through” with a primary and secondary systematic search of a scene, collect, package, and establish a chain of custody, and transmit various types of physical evidence to the crime laboratory.

Fingerprints

Fingerprint Evidence

Documentation and analysis of fingerprints collected at a scene or processed in person requires technical knowledge for applying the proper procedure determined by location and type of print. Investigators may utilize ink, powders, chemicals, or cyanoacrylate vapor when developing, lifting, recording, and documenting prints. Forensic labs can analyze fingerprint evidence to make identifications by examining and comparing print minutiae such as bifurcations, ending ridges, dots, and short ridges. 

Impression

Impression Evidence

The recovery and documentation of surface characteristics produced by impression evidence is performed by casting and molding impressions such as tires, shoes, and tool marks. Proper protection and processing of impressions is essential for maintaining evidence integrity and viability for comparison, analysis, and ultimate use in potential legal proceedings.

Hair and Fiber

Hair and Fiber Evidence

Hairs and fibers are essential examples of trace evidence that require careful detection, collection, and submission to crime labs. Interpretation of the results from crime lab analysis obtained by microscopy, chemical, or flame tests can reveal information to apply in solving a case such as the human or non-human origins of hair or connecting natural or synthetic fibers to samples obtained from a suspect.

Glass

Glass Evidence

Glass evidence can be used as trace evidence and to provide insights into projectiles or collisions. Fragments of glass at a scene can be identified by type, such as soda lime, borosilicate, leaded, and tempered, and analyzing glass fracture patterns can reveal the direction of projectiles.

Document

Questioned Document

Forgery and counterfeiting produce questioned documents that a forensic investigator may be called upon to analyze and identify the authenticity of (or lack thereof) in a court of law. Document examinations may include paper chromatography, ink analysis, and comparisons of unknown samples with exemplars by analyzing handwriting characteristics such as letter, line, and formatting.

Firearms and Ballistics

Firearm and Ballistic Evidence

Law enforcement services at a crime scene may encounter evidence produced by firearms, ballistics, or explosives. This includes, but is not limited to, gunshot and explosive residue, bullet and cartridge cases, firearms, and impacts from projectiles that can be analyzed to identify the trajectory, point of origin, and angle of the impacting object.

Crime Scene Resources

Substances

Controlled and Illicit Substances

Legally defined controlled or illicit substances have unique characteristics and procedures that law enforcement must be equipped to respond to for public safety. The handling of dangerous and sometimes lethal drugs, or processing of individuals who have consumed them, may require identification of unknown substances using presumptive and confirmatory procedures or the administration and interpretation of drug screening tests, such as urinalysis or blood alcohol concentration test.

Toxicology

Forensic Toxicology

The accidental or intentional consumption or exposure to toxins are potential health, safety, and environmental hazards law enforcement and public safety officers should be prepared to identify, document, and resolve. In legal proceedings, forensic investigators may be called to describe presumptive and confirmatory laboratory procedures as they relate to toxicological incidents and the absorption, distribution, metabolization, and elimination of toxins.

Blood

Blood Evidence and Blood Spatter

When blood is discovered at a scene, investigators should be able to conduct and interpret blood presumptive testing in addition to following proper collection and documentation procedures. Blood spatter or blood stain patterns can further be analyzed based on surface type and appearance such as size, shape, distribution, and location in order to determine the mechanism by which the patterns are created.

Biological

Biological Evidence: DNA and Blood Typing

The crime scene investigation techniques used to collect, protect, and document biological and DNA evidence are paramount for evidence preservation and interpretation by forensic scientists in crime labs. By generating a DNA profile from DNA extraction, quantification, amplification, and electrophoresis, different types of DNA analysis such as short tandem repeats (STRs), Y-STRs, mitochondrial DNA, and single nucleotide polymorphisms (SNPs) can be performed and contribute to solving a case. Blood typing additionally provides a tool for biological evidence to be identified and analyzed for consistency with suspects or unknown persons.

Crime Scene Resources

Investigations

Death Investigations

When a case involves death or human remains, investigators can interpret wounds and injuries or the presence of insects such as blowflies to document and analyze evidence for the recreation of events or determination of a postmortem interval. By autopsy the cause and manner of death can be identified and the stage of decomposition (rigor) can aid in identifying a time of death.

Anthropology

Forensic Anthropology and Odontology

The principles and techniques of anthropology and odontology are relevant to a forensic scientist’s ability to interpret and analyze bone and dental evidence. Skeletal remains can be analyzed to identify characteristics of a person such as age, sex, and height. The impressions created by human bites and relevant remains such as teeth, dentures, and implants can be analyzed for consistency with suspects and identify characteristics about individuals.

Motor Vehicle

Motor Vehicle Accidents

In compliance with prescribed procedures, law enforcement can be called to Investigate and document a motor vehicle accident and to analyze crash scene evidence using standard laws, regulations, and procedures. This can include interpreting crash scene evidence by reconstructing the crash and performing a variety of mathematical calculations using formulas including speed calculations, acceleration, and drag factor measurements.
