Skill 4: The Crime Scene SketchRelates the sequence of events at the sceneEstablishes the precise location & relationship of objects and evidence at the scene.A crime scene sketch assists in:1. and interrogating persons2. Preparing an investigative report3. Presenting the case toThe sketch photographs, notes, plaster casts and otherinvestigative techniques.The Rough Sketcho The rough sketch is the first outline of the sceneo Shows the location of objects and evidence within this outline.o Although are measured with a tape measure andindicated in the sketcho Sketch after photographs are taken and before anything is movedo Sketch as much as possible by the naked eyePlotting Methods:Plotting methods are used to locate objects and evidence on the sketch.o They include the use of:- Rectangular coordinates- Baseline method- Triangulation
:Uses two adjacent walls as fixed points asdistances are measured at right anglesBaseline Method:Run a from one fixed pointto another, from which measurements are taken atright angles.Triangulation:Uses straight-linemeasurements from twofixed objects to theevidence to create atriangle with evidence in theangle formed by two straight lines.Steps in Sketching the Crime Scene1) Walk the perimeter of the room and look at clues and evidence leftbehindTry to recreate the crime as it happenedPlan where you will begin drawing2) Measure total distance of the walls, as well as location from both sides ofdoors and windows3) Start with large furniture or fixed objects in the room and correctly orient inthe room as well as measure dimensions (length & width)
Provide measurements of these fixed objects as well as theirmeasurements to the perimeter of the roomRecord additional details about these objects somewhere off to the sideof the sketch4) Correctly orient in the roomProvide measurements of evidence whennecessaryRecord details about these objects (out ofplace, upside down, color, etc)o (what looks out of place, color of,number of, etc)The Final SketchThe finished sketch is drawn tofrom information on the roughsketch Determine scale based on size of roomWalls, doorways, windows and furnituremust be drawn to scale are all included A legend or is provided to identify evidence

Crime Scene is the area where the original crime occurred. The Secondary Crime Scene comprises of the subsequent crime scenes. The Size of the crime scene can further be classified as Macroscopic and Microscopic. While Microscopic focuses on specific type of physical evidence at the crime scene, Macroscopic refers to one particular crime .
b. Be aware of any persons or vehicles leaving the crime scene. c. Approach the scene cautiously. d. Assess the scene for officer safety. e. Remain alert and attentive. f. Tr eat location(s) as a crime scene until determined to be otherwise. Performance Given a crime scene scenario, the student is expected to demonstrate overall scene aware-

For D1, students will evaluate their processing of the crime scene, and show how the evidence collected could be used in the investigation.

CHAPTER Crime-Scene Investigation and Evidence Collection 2 The 1996 homicide investiga-tion of six-year-old JonBenet Ramsey provides valuable les-sons in proper crime-scene investigation procedures. From this case, we learn how impor-tant it is to secure a crime scene. Key forensic evidence can be lost forever without a secure crime scene.

of general rough paths. However, in this paper, we will focus on the case where the driving signal is of bounded variation. Following [6] we interpret the whole collection of iterated integrals as a single algebraic object, known as the signature, living in the algebra of formal tensor series. This representation exposes the natural algebraic structure on the signatures of paths induced by the .
