When physical items cannot bepreserved in their found state, document it.4.3Photographic DocumentationCommence photographic documentation as soon as possible after the incident. Document thescene of the incident and the condition of items invol
17、ved. If items involved in the incident are disassembled or subjected todestructive testing, each step of the disassembly or testing shall be documented by contemporaneous photographs or videotaping.The preferable photographic technique provides negatives that can be reproduced and enlarged. The date
18、, time, and location of thephotography or videotaping, and identity of the photographer or videotaper, shall be recorded.4.4Collect information related to events and conditions occurring before, during, or after the incident.

Obtain statements as early as feasible from all individuals associated with the incident and the recovery activity.3.2 Physical Evidence:3.2.1 Plan the investigation to protect physical evidence significant to the incid
20、ent. The plan should consider the possibility ofidentity loss, physical loss, or the deterioration or destruction of information due to environmental effects or the recovery andcollection activities. For each item considered to be significant to the incident, document, collect and preserve physical
21、items andtheir information content as soon as possible.3.2.2 Document conditions that prevent or interfere with the preservation of any potential evidence in the state in which it wasfound. This might include hazardous or accessibility conditions, weather conditions, or other existing complications.
22、3.2.3 Assign a unique identifier to each item collected and include this information in a label securely attached to the item oras documentation on the items container and enter the identifying information on a log sheet together with a brief description ofthe item. The evidence documentation should
23、 also clearly include any specific details necessary for preservation of the item, suchas temperature control or special handling instructions.3.3 Photographic Documentation:3.3.1 Commence photographic documentation as soon as possible after the incident. Document the scene of the incident andthe co
24、ndition of items involved.3.3.2 Potential evidence should be photographed in the position where it is first observed by the investigator. If items involvedin the incident are disassembled or subjected to destructive testing, each step of the disassembly or testing shall be documentedby contemporaneo
25、us photographs or videotaping.3.3.3 The photographic technique utilized should be of sufficient resolution to preserve the essential aspects of the appearanceof the evidence being photographed, and should also be capable of producing images that can be reproduced and enlarged. Thedate, time, and loc
26、ation of the photography or videotaping, and the identity of the photographer or videotaper shall be documented.3.4 Validation and AuthenticationEvidence and information gathered by investigators must be admissible in the event oflitigation. Validity and authenticity must be established and the chai
27、n of custody traceable. Validity and authenticity of evidenceis established by documentation that defines the relationship of the evidence to the incident. Such documentation includes, but isnot limited to, the following:4.4.1To support the admissibility of evidence and information, the validity and
28、 authenticity must be established and the chainof custody traceable. Validity and authenticity of evidence is established by documentation that defines the relationship of theevidence to the incident. Parts of this documentation may be located within the records of different agencies; however, it is
29、 theintention of this practice that the history of custody should be capable of being reconstructed to reflect the entire lifetime of theevidence. Such documentation includes, but is not limited to, the following:3.4.1 Initial Collection Information. Document the following:43.4.1.1 Identity of the e
