What are the methods for searching a crime scene?

Following are the basic search methods, usually commissioned on the crime scene:

• Zonal Method.
• Strip Method.
• Line Search.
• Grid Method.
• Spiral Method (Outward Spiral & Inward Spiral)
• Wheel Search Method.
• Random Search.

What is a grid search police?

The grid search: A grid search is simply two parallel searches, offset by 90 degrees, performed one after the other. The inward spiral search: The CSI starts at the perimeter of the scene and works toward the center. Spiral patterns are a good method to use when there is only one CSI at the scene.

What are 3 search methods used in crime scenes?

Common search patterns include the spiral, strip/line, grid, zone/quadrant, and pie/ wheel. The spiral search is used most often for outdoor crime scenes, is conducted by one person, and is done by walking in a circle from the outermost point of the inner perimeter toward the center of the circle.

What are the 4 types of crime scene searches?

Most commonly employed search methods are geometric patterns. The six patterns are link, line or strip, grid, zone, wheel or ray, and spiral. Each has advantages and disadvantages and some are better suited for outside or indoor crime scenes.

What is grid method search?

The grid method is best used in large crime scenes such as fields or woods. Several searchers, or a line of them, move alongside each other from one end of the area to be searched to the other.

What are search methods?

What is a search method? A search method is a way of efficiently and effectively finding the information you need to answer your research question.

When would you use a grid search pattern?

A grid search is an effective way to search an exterior scene or an intricate interior one. This is due to the fact that this type of search pattern covers almost every inch of the crime scene.

What are the four search methods?

What are the 4 main types of search patterns?

Types of Crime Scene Searches Common search patterns include the spiral, strip/line, grid, zone/quadrant, and pie/ wheel.

What are the different methods of searching?

Searching Algorithms :

• Linear Search.
• Binary Search.
• Jump Search.
• Interpolation Search.
• Exponential Search.
• Sublist Search (Search a linked list in another list)
• Fibonacci Search.
• The Ubiquitous Binary Search.

What are the 5 basic information search techniques?

The search techniques introduced on this webpage are: Boolean operators, phrase searching, truncation/wildcards, and nesting.

How does a grid search work in a crime scene?

A grid search is an effective way to search an exterior scene or an intricate interior one. This is due to the fact that this type of search pattern covers almost every inch of the crime scene. Investigators will begin in one direction, then search from another direction – crossing over some of the area already searched.

Which is the best method to search a crime scene?

The line method is best used outdoors as well, and is similar to the grid search with the exception that searchers generally only move in one direction, from one side of the search area to the other. Because of trees, shrubs, rocks or other objects that may make a grid search unfeasible, the line method search is the next best method to use.

How are two parallel strips used to search a crime scene?

If two personals are employed, then each of them can start from two different points and continuing to the different ends to double check the search. Grid Method (two parallel strip): It is just like the strip method; the only difference is that two strips are considered to form a grid.

Can a virtual strip search be used at a crime scene?

This method cannot be applicable on very squeezed and complex crime scenes like elevators, lift shafts, or stairs. Strip or Parallel Method: In this method the virtual strips or line are being imagined to walk through on the crime scene and look for the evidences.
