9LINESRCH..PPT LAST REVISED: 9 JULY 2008 Citizens Serving Communities Parallel Sweep Used to search specific gridded areas typically Normally use a Line Search formation
10
10LINESRCH..PPT LAST REVISED: 9 JULY 2008 Citizens Serving Communities Expanding Square or Circle Search small areas for missing person or clue Normally use Hasty team
11
11LINESRCH..PPT LAST REVISED: 9 JULY 2008 Citizens Serving Communities Contour Search Searching by elevation –top to bottom not normally very feasible – statistically people get hurt climbing, not on the way back down Normally looking for hikers along trails or on side of trails –Use the Wedge formation for this pattern
12
12LINESRCH..PPT LAST REVISED: 9 JULY 2008 Citizens Serving Communities Missing Person Search Clues Physical clues –Clothing or equipment –Smoke, by sight or smell –Food wrappers, trash or cigarette butts –Broken or disturbed brush or other signs of humans passing through an area –Scavengers –Decomposition Odors
13
13LINESRCH..PPT LAST REVISED: 9 JULY 2008 Citizens Serving Communities Missing Person Search Clues Continued Recorded Clues –Trail registers –Sign-in logs People –Witnesses –Trained personnel like other searchers or Forest Rangers –Family and Friends
14
14LINESRCH..PPT LAST REVISED: 9 JULY 2008 Citizens Serving Communities Missing Aircraft Search Clues Terrain Changes –Broken or disturbed trees and underbrush –Landslides –Horsetails caused by windblown snow or sand –Breaks in terrain –Blackened or discolored areas –Smoke –Presence of Scavengers
15
15LINESRCH..PPT LAST REVISED: 9 JULY 2008 Citizens Serving Communities Missing Aircraft Search Clues Smells –Smoke –Decomposition Odors –Fuel, oil or Brake Fluid Aircraft Signs –Pieces of wreckage (twisted metal, seats, etc.) –Fuel, oil, or brake fluid –Shiny metal in the distance
16
16LINESRCH..PPT LAST REVISED: 9 JULY 2008 Citizens Serving Communities Missing Aircraft Search Clues Signs of the Pilot/Passengers –Bits of clothing or personal effects –Trail markings –Footprints –Campfires –Garbage –Signals (Flares, Mirrors, etc.) Unusual events (Voices, creaking metal)
17
17LINESRCH..PPT LAST REVISED: 9 JULY 2008 Citizens Serving Communities Voice Commands Forward the Line Halt the Line
18
18LINESRCH..PPT LAST REVISED: 9 JULY 2008 Citizens Serving Communities Whistle Signals 1 short - Go 2 short - Stop 3 short - Danger, but keep moving unless you encounter a problem that you must stop for. 1 long - Assemble on the team leader
19
19LINESRCH..PPT LAST REVISED: 9 JULY 2008 Citizens Serving Communities What do you do when you find a clue or the target? Halt in Place Alert the Team Leader Look for hazards in your area Do not disturb anything Brief the Team Leader on what you found Mark the area if necessary to prevent damaging of this or other potential clues (covered in later slide)
20
20LINESRCH..PPT LAST REVISED: 9 JULY 2008 Citizens Serving Communities Marking a Route Mark area searched for future teams or return leg Determine color and type to use –Surveyors tape (Recommended) –Crepe Paper Streamers (Party supplies) –Toilet paper for temporary marking (biodegradable) Place markings at eye level when possible Slow the team down as necessary to leave a good marking
21
21LINESRCH..PPT LAST REVISED: 9 JULY 2008 Citizens Serving Communities Suggested Route Markings 1 Strand = temporary edge of search pattern 2 Strands = outside edge of search pattern 3 Strands = clue, marked with: –Time & date –Clue number –Team ID
