April 24, 2013 - John Beck and K9 Athena Demonstrate Cadaver Search Dog Techniques

UNL Forensic Science - John Beck and AthenaAs part of the FORS 200 - Forensic Seminar guest lecture series, John Beck, cadaver detection dog trainer and handler, brought his K9 Athena to discuss using search dogs to find human remains.

Beck and Athena, an Australian Cattle Dog trained as a cadaver detection dog, demonstrated how she uses her olfactory senses to ascertain the location of human remains. Beck has trained her to use aggressive indications like barking and scratching to identify the location of human remains. 

Beck indicated that Cadaver dogs, unlike many other detector dogs, are usually civilians and their handlers are volunteers.  He uses real human remains to train his dogs and said it usually takes 5 days or less to train a dog with good drive.  More…

April 17, 2013 - Jim Jenkins Presents Forensic Odontology - NE Dental Forensic Team

UNL Forensic Science - Jim Jenkins

As part of the FORS 200 - Forensic Seminar guest lecture series, Dr. Jim Jenkins, Assistant Professor of Dentistry at UNMC Dental School, gave a presentation providing information about Forensic Odontology and the work of the Nebraska Dental Forensic Team.

Jenkins indicated that Forensic Odontologists use their knowledge of teeth to make positive identifications and exclusion of individuals based on their dental records.  X-rays are taken postmortem (after death) and compared with antemortem (before death) images to identify distinguishing features in the set.  Jenkins noted that it only takes 3-4 extraordinary features to make a positive ID.

Teeth are a good way to identify bodies, Jenkins says, because they are the hardest substance in the body and can withstand temperatures one would find in fires.  Since there are 160 surfaces to identify someone from a dental exam, there is a lot of room for comparison.  The Dental Forensic Team can also make identifications from bite marks.

Sept. 13, 2012 - Amanda Fujikawa Featured in Scientific American

Amanda Fujikawa

Amanda Fujikawa’s graduate research may change the way insects are considered in determining post-mortem intervals.  Her work has shown that insect behavior and morphology may be more complicated than previously believed.

Her findings may significantly impact the field of Forensic Science, and if some of these variables can be further studied and confirmed, post-mortem interval may be determined with more accuracy.

Fujikawa has also demonstrated that adult blowflies can alter the morphology of blood stains at a crime scene and she has identified novel ways of distinguishing blood spatter from bug activity.

Amanda’s contributions have not gone unnoticed and her work has been highlighted in Scientific American.  More…
