conduct scene assessment
talk to first responder
evaluate safety issues
evaluate search and seizure issues
evaluate path of scene entry/exit
evaluate inital scene bounderies
determine size and number of scenes
crime scene management
establish a staging area for consultation and equipment
establish communication between individuals at multiple scenes
establish secure area for tempory evidence storage
determine additional resource requirments
ensure scene integrity/security
ensure preliminary documentation/photography
conduct scene walkthrough and initial documentation
minimise scene contamination
prepare preliminary documentation

ensure contamination control
document scene
prioritise collection of evidence

prioritise collection of evidence
easily accessible areas in open view first
systematic search pattern
multiple scenes
collect, preserve, inventory, package, transport, and submit evidence
maintain scene security
document type, location, date and who collected evidence
chain of custody
avoid excess handling of evidence after collected
transport and submit for secure storage
strip or lane search
large open areas
personnel will line up shoulder to shoulder, move slowly along examining parallel strips of terrain
when suspected piece of evidence located they will call team leader before taking any action
personnel should try to maintain the straight line and move forward together to avoid missing areas
grid search method
used outdoors
personnel will search a strip along one axis, east to west and then come back and cover the same area on a north to south axis
