  • Cybergenetics :: No DNA left behind: When "inconclusive" really means "informative"
    Schenectady NY 31 Jan 2014 Talk PowerPoint presentation with live audio recording of Dr Perlin s talk Download Handout Download PowerPoint Abstract Biological evidence is often a mixture of two or more people which can pose DNA interpretation challenges Human review of mixed or low level data can lead to inconclusive results or greatly understate a match statistic erasing DNA s evidentiary value But computer interpretation of the same data

  • Cybergenetics :: DNA Mixture Interpretations and Statistics - To Include or Exclude
    defendant s or victim s DNA profile is included or excluded And if the profile is included there must be a statistic to demonstrate the significance of the inclusion This panel will discuss the variance in mixture interpretations and statistics throughout crime laboratories in the United States Conclusion Our focus is DNA truth and criminal justice Yesterday was D Day so let us recall what Winston Churchill once said This truth is incontrovertible Panic may resent it ignorance may deride it malice may distort it but there it is Genotype models are more accurate than threshold methods Computer models can preserve identification information in DNA evidence that helps make society safer TrueAllele 174 computing is thorough and objective and gives accurate answers that manual methods cannot Who cares about accurate DNA answers Why does it matter The police want a highly effective DNA evidence database to help catch criminals By uploading 100 of mixture evidence to the database instead of the 10 used now they have a better chance of solving crimes Most prosecutors are passionate about the truth They want to try the right person and convict the guilty based on solid DNA evidence A defender wants to exonerate

  • Cybergenetics :: Unleashing Forensic DNA through Computer Intelligence
    rape kits that could identify true culprits is routinely collected and analyzed but often never used This investigative failure and evidential defeat occurs because the unassisted human mind cannot cope with the complexities of challenging DNA evidence These DNA challenges include a mixtures of two or more individuals b small quantities of DNA and c degraded or damaged DNA Such challenges introduce interpretation uncertainty Television drama DNA data looks obvious and will uniquely identify a suspect But real world evidence can actually be consistent with many different individuals Forensic experts cannot sort through these millions of possibilities and so conclude very little or say nothing at all Thus highly informative DNA evidence that could solve or prevent crime lies dormant and remains unused Computer intelligence can help people overcome these data challenges Statistical search explores the vast space of genetic possibilities to find the likely solutions and quantify their probability An investigator can ask the computer forensically meaningful questions and receive accurate informative answers Objective computation examining only the evidence without ever looking at a suspect ensures unbiased results Cybergenetics TrueAllele 174 Casework is the most sophisticated computer system available for this task Starting with DNA data and forensic questions TrueAllele produces reliable probabilistic genotypes for genetic identification Unlike human expert approximations the extensively validated TrueAllele strives to preserve all the identification information present in the data This information preservation means that a new kind of probabilistic genotype investigative DNA database can identify criminals terrorists and missing people with far greater accuracy In criminal cases comparing a probabilistic genotype from evidence with a defendant provides a highly informative DNA match statistic TrueAllele s computer intelligence can identify implicate or exonerate depending only the evidence and is not influenced by a desired outcome TrueAllele has been used in over a hundred

  • Cybergenetics :: Whose DNA Is It Anyway?
    the guilty but only when it is actually used Government agencies control DNA evidence However most have not yet adopted newer analysis methods and databases that get better information from the same data Many agencies restrict access to data that can help criminal justice or prevent crime What should the public expect for the billions it spends on forensic DNA How should DNA information be used for criminal identification Who should have access to DNA data What are the privacy issues involved Where is the ethical boundary between DNA safety and societal surveillance Can we prevent rapes homicides and other crimes by making better use of existing DNA information How might competition help improve government forensic DNA practices The field of forensic DNA analysis constitutes a premier method for prosecuting and convicting the guilty while at the same time absolving the innocent said Dr David Seybert dean and professor of the Bayer School of Natural and Environmental Sciences which is co sponsoring the seminar It is imperative that forensic practitioners and the criminal justice community engage in this type of dialogue in an ongoing basis In addition to the Wecht Institute and the Bayer School Whose DNA Is it Anyway
