CRIME SCENE LEGAL ISSUES A CRIME IS AN ACT OR OMISSION THAT CONSTITUTES AN OFFENSE AND MAY BE PROSECUTED AND PUNISHED IN A COURT OF LAW. NOT ALL CRIMES ARE THE SAME SEVERITY: INFRACTION/VIOLATION USUALLY MINOR AND GENERALLY PUNISHABLE BY A FINE. EX: TRAFFIC OR
PARKING TICKET. MISDEMEANOR LESS SERIOUS THAN A FELONY AND PUNISHABLE BY NO MORE THAN A YEAR IN JAIL. EX: PETTY THEFT, FIRST TIME DUI, LEAVING THE SCENE OF A CRIME. FELONY SERIOUS CRIME THAT IS PUNISHABLE BY MORE THAN A YEAR IN JAIL AND POSSIBLY THE DEATH PENALTY. EX: MURDER. 4TH AMENDMENT THE RIGHT OF THE PEOPLE TO BE SECURE IN THEIR PERSONS, HOUSES, PAPERS, AND EFFECTS, AGAINST UNREASONABLE SEARCHES AND SEIZURES, SHALL NOT BE VIOLATED, AND NO WARRANTS SHALL
ISSUE, BUT UPON PROBABLE CAUSE, SUPPORTED BY OATH OR AFFIRMATION, AND PARTICULARLY DESCRIBING THE PLACE TO BE SEARCHED, THE PERSONS OR THINGS TO BE SEIZED. PROVIDES PROTECTION AGAINST UNLAWFUL SEARCH AND SEIZURE APPLIES TO ALL CRIMES. EVIDENCE EVIDENCE BODY OF FACTS OR INFORMATION INDICATING WHETHER A BELIEF OR PROPOSITION IS TRUE OR
VALID. TWO MAJOR CLASSIFICATIONS OF EVIDENCE: CLASS EVIDENCE MATERIAL THAT CAN BE ASSOCIATED ONLY WITH A GROUP OF ITEMS THAT SHARE PROPERTIES OR CHARACTERISTICS INDIVIDUAL EVIDENCE MATERIAL THAT CAN BE RELATED TO A SINGLE SOURCE OR PERSON, INDIVIDUALIZATION ALWAYS INVOLVES A COMPARISON.
EVIDENCE (CONT.) TYPES OF EVIDENCE DIRECT EVIDENCE (TESTIMONIAL EVIDENCE) STATEMENTS MADE UNDER OATH SUCH AS EYEWITNESS ACCOUNTS AND EXPERT WITNESS STATEMENTS. PHYSICAL EVIDENCE TANGIBLE ITEMS FOUND AT THE CRIME SCENE, ON THE VICTIM, OR IN THE SUSPECTS POSSESSION, THAT PROVE A MATERIAL FACT. EX: FINGERPRINTS, BODY FLUIDS, GUNSHOT RESIDUE. INDIRECT EVIDENCE (CIRCUMSTANTIAL EVIDENCE) NEITHER PROVES NOR DISPROVES A FACT IN QUESTION, BUT PROVIDES AS BASIS FOR INFERENCE.
EX: DNA LEFT AT A CRIME SCENE IS CONSIDERED INDIRECT UNLESS SOMEONE SAW THE PERSON ACTUALLY LEAVE THE SAMPLE OF DNA BECAUSE IT COULD HAVE BEEN LEFT AT ANOTHER TIME. ARRIVAL AT THE CRIME SCENE Upon arrival at a crime scene the first responding police officer to a crime scene is responsible for: 1. Acquiring medical assistance for injured victims Medical personnel avoid disturbing
evidence and approach the victim by an indirect route. 2. Detaining any potential suspects or witnesses 3. Obtain statements from victims, witnesses, and suspects. ARRIVAL AT THE CRIME SCENE 4.
Securing the crime scene to the greatest extent possible The boundary is sealed off, and guards are posted at the entry to the crime scene if needed. All civilians and unauthorized personnel are excluded from the crime scene. 5. Calling for any additional personnel needs such as other officers and/or forensic investigators. The personnel required depends upon the nature of the crime scene. RECORDING THE CRIME
SCENE Photography, sketches, and notes are the three methods for crime-scene recording. Ideally, all three should be employed CRIME SCENE NOTES Note taking begins when the investigator is contacted and requested to report to the crime scene. The crime scene notes should begin with: The identity of person who contacted the investigator
Time of contact and arrival at the crime scene Preliminary case information Personnel present on arrival and those being contacted CRIME SCENE NOTES Notes contain a personnel log, all observations made by the investigator, and the time observations were made. Notes are taken in a uniform layout, concurrently as the observations are made. Notes are written in a bound notebook in blue or black ink.
CRIME SCENE PHOTOGRAPHY Crime scene photographs should record the area in which the crime actually took place and all adjacent areas where important acts occurred. The most important prerequisite for photographing a crime scene is for it to be in unaltered condition. Each crime scene should be photographed as completely as possible in a logical succession. The sequence will show the overall scene first, then work down to individual pieces of evidence that jurors in the trial can easily relate back to the larger scene.
CRIME SCENE PHOTOGRAPHY The four minimum photographs required at a crime scene are: an overview photograph, a medium range photograph, a close-up photograph, and a close-up photograph with a scale. Overview photographs of the entire scene and surrounding area, including points of exit and entry, are taken first. Taken from the outside borders of the scene and from various angles If the crime scene includes a body, photographs must show the bodys position and location relative to the entire scene. Include a visual tag, an object recorded in multiple
overview photographs, to help visually piece the scene together PHOTOGRAPHY CRIME SCENE PHOTOGRAPHY Medium-range photographs show the layout of smaller significant areas of the crime scene: Taken with evidence markers in place to show the spatial relationships between and among pieces of evidence in greater detail than the overview photographs. Include at least one photograph of the
center of the scene. In violent crimes, this usually includes the site where the victim was found and the surrounding area. CRIME SCENE PHOTOGRAPHY Close-up photographs are taken last and show greater detail of individual objects or evidence: Taken at a 90 angle to the object, with and without evidence markers and scales. Scales should be placed as close to the evidence as possible without affecting it in any way. After the 90 photographs have been taken, photographs from other angles may be taken.
The most important close-up photographs are those depicting injuries and weapons lying near a body. After the body is removed from the scene, the surface beneath the body should be photographed. VIDEOTAPING CRIME SCENES As with still crime scene photography, the crime scene video must include overview, medium-range, and close-up images. A narrated crime scene video combines photography and notes. However, it is important that only one person narrates and no side conversations are captured on
the video. Some video cameras can produce still photographs, but the quality is often poor. Therefore, still photographs from a digital camera are still required. SURVEYING THE CRIME SCENE The Walkthroughinitial survey of the crime scene 1. Perpetrators point of entry and exit are located. 2. Indirect path is taken to the center of the crime scene.
3. Obvious items of evidence are located and documented. 4. The conditions of the scene are observed and recorded. Special attention is paid to item or conditions that suggest timing of the incident or do not appear to belong. SEARCHING THE CRIME SCENE Line/Strip Search Pattern One or two investigators start at the boundary of the crime scene
and search in straight lines across to the other side of the crime scene. Grid Search Pattern Two or more investigators form a grid by searching in line patterns that overlap and are perpendicular to each other. SEARCHING THE CRIME SCENE Spiral Search Pattern One investigators searches in a spiral path from the center of the crime scene to the boundary (outward) or from the boundary of the crime
scene to the center (inward). Wheel/Ray Search Pattern Several investigators search in straight lines from the center to the boundary (outward) or from the boundary to the center (inward). Quadrant/Zone Search Pattern The crime scene is divided into smaller sections (zones). One or more investigators are assigned to search each zone. Several typical examples of crime-scene search patterns. The pattern selected normally depends on the size and locale of the scene and the number of collectors participating in the search.
SEARCHING THE CRIME SCENE Vehicle Searches: Investigators search interior and exterior of vehicle. The vehicle may be searched at the crime scene or at the police department or crime laboratory garage. SKETCHING THE CRIME SCENE Crime scene sketches: Clearly show the layout of a crime scene Illustrate the relationship in space of all
significant items and features Clarify objects and features already described in notes or shown in photographs Show measurements over long distances and topography of outdoor scenes Depict possible paths of entry, exit, and movement through the scene THE ROUGH CRIME SCENE SKETCH A rough sketch is created at the crime scene and contains an accurate depiction of the dimensions of the scene and shows the location of all pertinent objects and features. All rough sketches include:
Title block with information on the case, crime scene, and person creating the sketch Legend with identity and dimensions of objects in the sketch Compass showing the North direction Body containing the sketch itself Points of reference for objects can be shown by the distance measurements from two fixed points.

The current standard method utilizes Computer-Aided Drafting (CAD) programs to create the finished sketch. CAD programs also allow for the creation of three-dimensional
finished sketches. FINISHEDSKETCH DIAGRAM OF A CRIME SCENE. Courtesy Sirchie Finger Print Laboratories, Inc., Youngsville, NC: www.sirchie.com FORENSIC SCIENCE: An Introduction by Richard Saferstein 28 ROOM SKETCH EARLIER, YOU DREW A SKETCH

PROCEDURES FOR COLLECTION Often, many items of evidence are clearly visible but others may be detected only through examination at the crime laboratory.
For this reason, it is important to collect possible carriers of trace evidence, such as clothing, vacuum sweepings, and fingernail scrapings, in addition to more discernible items. PROCEDURES FOR COLLECTION Investigators handle and process physical evidence in a way that prevents changes to the evidence through contamination, breakage, evaporation, accidental scratching or bending, or through improper or
careless packaging. The use of latex gloves, disposable forceps, and sanitized equipment reduces the chance for contamination. Whenever possible, one should keep evidence in its original condition as found at the crime scene. PACKAGING Each different item or similar items collected at different locations must be placed in separate containers. Packaging evidence separately prevents damage through contact and prevents cross-contamination.
The well-prepared evidence collector will arrive at a crime scene with a large assortment of packaging materials and tools ready to encounter any type of situation. PACKAGING Disposable forceps and similar tools may have to be used to pick up small items. Unbreakable plastic pill bottles with pressure lids are excellent containers for hairs, glass, fibers, and various other kinds of small or trace evidence. Alternatively, manila envelopes, screw-cap glass vials, or cardboard pillboxes are adequate containers for most trace
evidence encountered at crime sites. Ordinary mailing envelopes should not be used as evidence containers because powders and fine particles will leak out of their corners. PACKAGING Sealable plastic evidence bags. Small amounts of trace evidence can also be conveniently packaged in a carefully folded paper, using what is known as a druggist fold. Evidence from arson scenes should be packaged in airtight metal or glass containers to
prevent the loss of accelerant vapors. PACKAGING If biological or bloodstained materials are stored in airtight containers, the accumulation of moisture may encourage the growth of mold, which can destroy the evidential value. In these instances, the material should be allowed to air-dry before being packaged in wrapping paper, manila envelopes, or paper bags. PACKAGING Contamination is a key concern during the
collection of DNA-containing specimens, such as blood, saliva, sweat or skin cells. Contamination can occur either by introducing foreign DNA through coughing or sneezing onto evidence or if items of evidence are incorrectly placed in contact with each other during packaging. To prevent contamination, the evidence collector must wear a face mask and lab coat, use disposable latex gloves and work with disposable forceps when collecting evidence that may contain DNA. Disposable coveralls, shoe covers, and eye protection offer added precautions to avoid contaminating DNA evidence. CHAIN OF CUSTODY
Chain of Custody: A list of all persons who came into possession of an item of evidence. Continuity of possession, or the chain of custody, must be established whenever evidence is presented in court as an exhibit. Adherence to standard procedures in recording the location of evidence, marking it for identification, and properly completing evidence submission forms for laboratory analysis is critical to chain of custody. This means that every person who handled or examined the evidence and where it is at all times must be accounted for. OBTAINING REFERENCE SAMPLES
Standard/Reference Sample: Physical evidence whose origin is known, such as blood or hair from a suspect, that can be compared to crime-scene evidence. The examination of evidence, whether it is soil, blood, glass, hair, fibers, and so on, often requires comparison with a known standard/reference sample. Although most investigators have little difficulty recognizing and collecting relevant crime-scene evidence, few seem aware of the necessity and importance of providing the crime lab with a thorough sampling of standard/reference materials.
DEPARTING THE CRIME SCENE The experienced lead investigator decides when all pertinent physical evidence has been recorded and collected at the crime scene. A final survey is undertaken to review the scene visually and collect all evidence and equipment. Following the final survey, the crime scene is released to the proper authorities. FORENSIC SCIENCE: An Introduction by Richard Saferstein
39 SUBMITTING EVIDENCE Evidence is usually submitted to the laboratory either by personal delivery or by mail shipment. Care must be taken in packaging evidence that will be sent by mail in order to prevent breakage or other accidental destruction during transit to the laboratory. Most laboratories require that an evidence submission form accompany all evidence submitted. Case information provided on this form enables the laboratory analyst to make an intelligent and complete examination of the
evidence. CRIME SCENE SAFETY Crime scenes frequently present the investigator with biological specimens of unknown origin. The investigator has no way of gauging what health hazards they may contain. One must use caution and protection at all times. CRIME SCENE SAFETY It is recommended that personnel always wear latex gloves and possibly chemical resistant
clothing, Tyvek-type shoe covers, a particle mask/respirator, goggles, or face shields when potentially infectious material is present. Gloves should be changed often. Personnel should maintain a red biohazard plastic bag for the disposal of contaminated gloves, clothing, masks, pencils, wrapping paper, and so on. CRIME SCENE SAFETY When processing and collecting evidence at a crime scene, personnel should be alert to sharp objects, knives, hypodermic syringes, razor
blades, and similar items. Eating, drinking, smoking, eating, and chewing gum are prohibited at the immediate crime scene. WAYNE WILLIAMS PROBABILITY ASSIGNMENT WAYNE WILLIAMS: THE USE OF FIBER EVIDENCE ARTICLE WAYNE WILLIAMS PROBABILITY STUDY QUESTIONS
