Digging out the Fire Scene
•Carefully looking for evidence within the debris
•Inspect the debris, layer by layer, from top to bottom
![Page 43: Role in Fire Investigation...• Any fire over $100.00 damage 2. Investigation Begun Within 2 Days of Event Required to Investigate Fires –cont. 3. Reporting –Notify State Fire](https://reader036.vdocument.in/reader036/viewer/2022070221/613aee9ef8f21c0c8268b7f0/html5/thumbnails/43.jpg)
Digging out the Fire Scene

•Sequence in which items burned
•Did it burn from top down or bottom up?
•How much burned?
•What burned?
•Artifacts
![Page 44: Role in Fire Investigation...• Any fire over $100.00 damage 2. Investigation Begun Within 2 Days of Event Required to Investigate Fires –cont. 3. Reporting –Notify State Fire](https://reader036.vdocument.in/reader036/viewer/2022070221/613aee9ef8f21c0c8268b7f0/html5/thumbnails/44.jpg)
Evidence
