Dna Mixture Statistics Using A Likelihood Ratio Software Tool: Effect Of Variations In Drop-Out Rates And Number Of Contributors, Felicia M. Lucero
Student Theses
Complex DNA mixtures can be very probative evidence, but comparisons to a person of interest can be affected by allelic drop-out and uncertainty regarding the number of individuals having contributed DNA to a sample. Scientific organizations such as the International Society of Forensic Genetics (Gill et al., 2006) recommend that likelihood ratios should be used to provide a statistical weight when a positive association is made between the DNA profile of a person of interest and an evidentiary DNA sample. To this effect the New York City Office of Chief Medical Examiner (OCME) developed a software program, Forensic Statistical Tool …

Dna Recovery From Handwritten Documents Using A Novel Vacuum Technique, Patrick M. Mclaughlin
Student Theses
Investigations of many crimes such as robberies, kidnappings, and terrorism are often associated with the recovery of a paper document which has been written by the perpetrator. Paper can provide a variety of forensic evidence such as DNA, latent fingermarks, and indented writing. The focus of this study was the collection of probative DNA profiles from the text region of a handwritten note through a vacuum suction device without altering or destroying the document. Collection of DNA evidence was carried out in two separate groups. The first group involved 11 volunteers providing a handwritten note sample with unwashed hands. The …
