Bloodstains are one of the most commonly found forms of evidence at crime scenes. Traditional methods of documenting and analyzing bloodstains require a significant amount of time at the scene. The use of laser scanning technology with FARO Scene’s Bloodstain plug-in is a validated and highly efficient method to perform area-of-origin analysis with the benefit of easily incorporating multiple, non-orthogonal surfaces into the results.

As Crime Laboratories have migrated to an ISO17025 accreditation status, there has been increased confusion regarding the calibration standards and requirements for microscope systems. This is especially true for comparison microscopes used in Firearm and Toolmark examinations.This webinar will discuss: the requirement levels and components used in calibration. the source of tools and process for calibration. the comparison microscope as it relates to ISO 17025 standards.
The DNAscan™ Rapid DNA Analysis™ System was developed to enable crime laboratories and law enforcement agencies to process DNA samples in under 90 minutes, thereby helping to accelerate the criminal investigation process. DNAscan System is fast, rugged, and easy-to-use and was initially designed and optimized to process single source, reference buccal swabs. Further development at NetBio is supporting expanded capabilities for the system.
Massively parallel sequencing (MPS), which has been described as next generation sequencing, has advanced substantially and offers the forensic scientific community novel and enhanced approaches to DNA typing. While capillary electrophoresis-based technologies have been the standard method for human identity typing applications, there are limitations in this methodology’s resolution, scalability, and throughput. MPS has the potential to address these limitations and expand investigative capabilities and typing success. Because of it, high throughput MPS provides the ability to multiplex multiple types of forensically relevant genetic markers and sequence multiple samples per analysis. Additionally, MPS data may improve interpretation of mixtures.
Perhaps you are often faced with compromised samples and questions such as: was the DNA concentration too low? Was the DNA degraded or the amplification inhibited? The new Investigator 24plex Kit family contains a unique Quality Sensor (QS) that generates valuable information for quality control and performance checks, which can be used to choose the most appropriate rework strategy.
This webinar will address in detail the method optimization parameters that effect extraction of drugs of abuse namely: sample pretreatment, bed mass, sample size, conditioning, column washing, drying and elution.
In the past 20 years, forensic DNA analysis has become an indispensable tool in the criminal justice system. Yet despite improvements in chemistry sensitivity and process automation, data generation has remained relatively unchanged. Currently, routine analysis is restricted to the length of STR alleles and only 10’s of markers can be combined in a single system. Comprehensive sample interrogation requires intensive workflows/methods and multiple parallel analyses.
The webinar will introduce the PowerPlex® Fusion 6C System, a 6-color STR system that simultaneously amplifies 23 autosomal loci, three Y-STR loci, and Amelogenin. The twenty required and three recommended expanded CODIS core loci are combined with Penta D, Penta E, DYS570, and DYS576 to give this system a discriminatory power that is unmatched by any other commercially available STR system.
The Hamilton easyPunch is a revolutionary automation solution co-developed by GE Healthcare and Hamilton Robotics designed for the forensic laboratory. The key design features of this technology include card and sample location imaging to obtain the optimum sample punch, full sample and card traceability and automated punching and liquid handling.
As forensic laboratories advance to newer and more sensitive instrumentation, it is useful to review how low level STR data is generated and interpreted. This webinar presentation will focus on the underlying instrumental and chemical factors that affect the appearance of low level DNA samples and mixtures, and will provide tips to attendees on how to appropriately address these challenges.
The need for at-site, rapid, reliable analysis of unknown compounds and materials is critical in forensic, environmental, homeland security and military applications. Agilent now provides key technologies that are optimized for at-site analysis and enable sampling of solids, liquids, air, gels, foods, and even blood. Results can be obtained in as little as a few seconds to a few minutes when and where you need answers.
Sexual assault samples are among the most difficult sample types encountered by forensic DNA laboratories, frequently suffering from multiple challenges including small quantity of male DNA, relatively high quantity of female DNA and presence of PCR inhibitors. Join this webinar to learn about powerful new tools for DNA sample assessment and amplification, including the Quantifiler® Trio, Yfiler® Plus and GlobalFiler® Kits, that can significantly improve the workflow for obtaining interpretable profiles from sexual assault and other challenging casework samples.
Forensic DNA laboratories rely on reagent and plastics manufacturers to supply high-quality products with minimal interference from contaminating DNA. With the increasing sensitivity of short tandem repeat (STR) amplification systems, levels of DNA that were previously undetected may now generate partial profiles. To address the concern of laboratories regarding the potential of low-level DNA contamination in consumables, ISO/CD 18385 has been drafted describing guidelines for minimizing the risk of human DNA contamination events during the manufacturing process. The draft also proposes pass/fail parameters for Forensic Grade certification. This webinar will discuss studies to evaluate the proposed parameters.
In this webinar, we will discuss the results from a large collaborative project initiated in September 2012 to collect, analyze, database and publish population data of 23 Y-STR locus haplotypes (PowerPlex® Y23 System which was released in August 2012).
The need for forensic laboratories to obtain more information in significantly less time from their STR analyses has increased steadily in recent years. The PowerPlex® ESX and ESI Fast Systems not only meet the ENFSI recommendation for DNA profile sharing across Europe, but they also use rapid cycling technology, so that amplification using these five-color systems can be done in less than 50 minutes.
For most death investigations, you start with a plain notebook and start writing. Wouldn’t it be easier to just fill in the blanks beginning with time assigned to the release of the crime scene? The Checklist is designed to help you investigate a crime scene. It covers bodies found in structures, water, vehicles and open areas; it will put your investigation into a format where the information can be found. This information will also work as a reminder of what needs to be done, to get you thinking and to be more observant, as well as aid in the prosecution of the case. Class participants will be given a code to access the Death Scene Check List free of charge.
