Forensics Expert Witness Report: Evidence Analysis and Findings

This report is a forensic expert witness report detailing the analysis of various types of evidence. The report includes the analysis of DNA, fingerprints, faunal, botanical, and sediment samples. The DNA analysis, conducted by ARCS2003 Group 1A, revealed that the gender of the individual is male, but there was no match in the comparison report. Fingerprint analysis indicated Mr. Jonathan Smith as a potential suspect. Faunal analysis identified a marine species from Rockhampton, while botanical analysis identified a tree species from the University of Queensland. Sediment analysis revealed a mixture of sand and silt from the Brisbane River. The total budget for the investigation was $2000, with $1000 allocated for the DNA test and $500 each for the other two tests. The report concludes that the available resources were effectively utilized to evaluate further clues and meet the needs of the investigation process.

ANALYSIS
DNA Analysis
Test conducted by ARCS2003 2017 Group 1A, reflects that the gender of individual is
male. There was no match in the comparison report which is critical issue for the investigation
team. Activities conducted by the other parties also focuses on the DNA test and it has been
identified that the male DNA is not matched with any other inconclusive. It means there was not
any criminal record of the suspect in the records of CrimTrac National Criminal Investigation
DNA Database.
Fingerprints
It is an analysis, in which green beer bottle has played a critical role in the testing
process. Key purpose of test is to have rige evidence so that overall outcome can be attained in
appropriate manner (Takats, 2015). In the analysis, it has been noticed that external surface of
item includes few circumstances so that objectives can be accomplished. Moreover, the identified
fingerprint on the bottle also indicates that Mr. Jonathan Smith can be suspect for further
investigation.
Faunal Analysis
It has been noticed in the case of Moulluse shell that Anadar granosa is a species of
marine which is mainly identified in the area from Rockhampton. It is considered as a species
which bivalve the endemic to tropical Indo-Pacific region. Other parties has also test the item 1b-
3 in order to compare the museum of Queensland and university’s of Queensland malacological
collection. Same result has indcated that Rockhampton is in Western Australia.
Botanical Analysis
It is an investigation that indicates that the results about micro and macroscopic aspects
which are associated with 3A-2. In addition to this, it can be stated that tree identified in the
investigation is of Jacaranda mimosifolia which is basically spotted at the University of
Queensland.
Sediment Analysis
Group ARCS2003 2017 Group 1A has also focused on the sediment analysis. In this,
sample of FS-192 is being considered as a critical aspect. It has been noticed in the test that
sediments are mixture of sand and slit (Popescu and Farid, 2014). The particles invested are

mainly recorded at the scale of 85 percent. It has been noticed that results identified are recorded
at the high score which are also linked with energy level. The sediment sample also contains
numerous small marine shells less than 3mm in maximum dimension. It has also been noticed
that sand is of Brisbane River which can be considered as critical value of further investigation.
Summary
On the basis of overall observation of diverse investigation, it can be said that overall
budget of the investigation is 2000. Number of test can not be taken into account for identifying
the issue. It has been noticed that sediment, fingerprint, DNA test are key aspect which can be
considered by experts in order to evaluate the outcome in available finance. It has been witnessed
that cost of DNA test is 1000 and other two test cost is 500. It means the activities can be
accomplished in the available resource effectively so that further clues can be evaluated. In
addition to this, it can be said that it also helps meeting needs of investigation process.
