Locating & Recovering Human Remains - continued // Reconnaissance ~ go to the scene but do not directly ENTER IT - take a look - we want to be able to see what is happening in the physical location that may restriction you including looking at: the terrain, vegetation and if any potential hazards are available Look at and analyze WHAT TYPE of search can be conducted 3 ways to searching for Human Remains: 1. Remote Sensing • via plane or satellite • aerial photography • thermal imaging Advantages of this are that a large area can be covered in a small amount of time. Disadvantages include being expensive, time consuming and weather must be cooperative in order to be successful. 2. Geophysical Methods • similar to an ultra sound where you bounce one wave down to the ground and an image is produced • ground penetrating radar or metal detector 3. Ground Search • this is the most common method • it is an ORGANIZED examination • everything is detailed and systematic Advantages include being easy to use, there is a lot of rapid coverage, accuracy is higher, everything is portable. Disadvantages include inexperienced searchers who can miss or destroy evidence. Planning – Resources • available expertise must be used in terms of person power and equipment! • Communication through a command center should be established • Personnel to document must be available aka IDENT OFFICERS • TIME must be available in order to conduct a search efficiently Remember that the POLICE secure the outer perimeter. We would set up a command post in the inner perimeter which is the SEARCH perimeter. A third can be added which can be around the body or around the burial site. Volunteers and personnel on hand must be briefed on hand about what to wear, park, bathrooms, food, what type of equipment will be required, what the background of the case is and any information pertinent to it. Telling all personnel what to look for is KEY and HOW to search. Ground Search – The Team • It is the SEARCH DIRECTOR’s job to organize a search line, make sure the line is straight and maintain a pace. • The Search Line is a collection of the VOLUNTEERS • Any experts will be found behind the volunteers • Following any experts will be the INVESTIGATING OFFICER and the IDENT OFFICER who will seize or photograph any evidence that is found. How to Search? 1. Keep an arm’s length apart from the person next to you 2. Lift LEAF litter 3. Move at the pace of the SLOWEST person 4. People are on one ednd of the flag of the search lane Search Patterns include: • line search • interlocking line • grid – is done going in one direction, turn around, and proceed in the opposite direction • ZONE • Spiral – circle formation done with 1 person! Start from a point of interest and go in a circle Search Indicators – Plants • in the first 6 months look out for LOW GROTH and dead plants due to damaged roots after someone has buried a body • AFTER 6 months – look for higher growth due to decomposition • Species will change over time from one plant to another • Looking for piles of brush is a clear indicator that a body or something has been buried. Search Indicator – Soil • Disturbed soil will be less compact and much easier to probe. A recent burial will show in a mound of dirt, different colors of dirt or you may find different soil types. If enough time has passed you may find a soil compaction site, which is an oval shaped depression in the ground. PROBES are ONLY used after a scene is searched completely. A test ground must be done before probing the s
