Crime scene log (who was at the crime scene, started by 1st responder) Note taking (done in ink with numbered pages to prevent tampering) Use photo log sheet (each item has a corresponding number to easily show tampering) Csis must be thorough but reflective-can"t collect everything. Hair (only in the root/follicle, not the shaft) Trace evidence is evidence found in very small amounts. Consider collecting entire item if small enough or mobile.
