Daubert Guidelines are

Back 1

a means of determining standards for the admission of scientific evidence in federal court

Front 2

5 Daubert criteria

Back 2

- The theory can be/has been tested

- It has been subjected to peer review and publication

- A known potential error rate

- Standards that control it’s operation

- Widespread acceptance within the scientific community

Front 3

Blowfly lifecycle

Back 3

- Fly lands on decomposing body and begins to feed

- Fly lays eggs within 6-40 hours

- 1st instar larva stage(small)

- 2nd instar larva stage(medium maggot) - 3rd instar larva stage(large maggot)- eats the most

- Pupae leaves body and becomes fly-- and the cycle begins again if flesh is left

Front 4

Mapping remains

Back 4

- First establish a datum point close to the remains, place on a permanent structure

- Once datum point is established the area around the body will be marked with a gridsquare to provide a frame for mapping findings

- Set up at least a 10x15 foot square usingwooden post at each corner

- Orient sides of square using NSE & W

- Use tape measure to locate/annotate bones in relation to sub datum point (a corner of the square)and photograph

Initial treatment of bones

Back 5

- Initial exam look for evidence of trauma and postmortem damage

-Bulk soft tissue removal radiograph and then use scalpel and tissue scissor to remove the bulk of the tissue remaining.

(Use care when getting closer to the bone.)

- Disarticulation separate articulated bones for further processing.

(Care mustbe taken to prevent damage to the bones.)

- Residual soft tissue removal, bones will be placed in vats for maceration of remaining tissue.

(Room temperature water can be used with or without enzymatic additive. Replacing water periodically can speed up the process.)

- Stabalization for safe handling
