Cataloging an Early American: A Question of Ancestry

A SKELETON WAS UNCOVERED during construction of a chimney in the town of Guilford, Connecticut in 1952 by the late Stanley Barnes (Figure 1). Based on personal communication, the human remains were found in a fetal position on a bed of shells, and the land owner believed the skeleton to be a Native American. After examination, two main issues seemed to be at odds with this conclusion. The first was the condition of the teeth. Normally, Native Americans are known to have good dental hygiene due to a non-sugary diet (Smith, 1984), but this individual’s oral cavity was in poor condition with obvious cavities in multiple teeth. The second issue was no associated artifacts or clothing were recovered from the burial site. However, due to the friable condition of the bones it is believed that the skeleton was extremely old and potentially Native American or early Colonial, and personal effects may have deteriorated at the burial site even if originally present. In this study, it was confirmed that the skeleton was female, and was likely young (aged 12-25 years) because of the undeveloped wisdom teeth.

Digital Evidence Management

This is a book excerpt from Implementing Digital Forensic Readiness: From Reactive to Proactive Process (2nd Ed.)

EVIDENCE IS A CRITICAL COMPONENT of every digital forensic investigation. Whether it is physical or digital, the methodologies and techniques used to gather, process, and handle evidence ultimately affect its meaningfulness, relevancy, and admissibility. Appropriate safeguards must exist throughout the investigative work to provide assurance that the lifecycle of evidence is forensically sound.

Collecting Evidence from Sexual Assault Cases

BEST PRACTICES have been identified by the National Institute of Justice (NIJ) and the Sexual Assault Forensic Evidence Reporting Working Group (SAFER) to assist jurisdictions and organizations working with evidence from sexual assault cases.

Angular Correction of Forensic Photographs

IT HAS LONG BEEN STRESSED that forensic photographers take close-up evidence photos with a scale perpendicular to the object or surface. The reason for that emphasis is that you may need to make precise measurements either of the object itself or the object in relation to something nearby. You rarely remember to take every necessary measurement while processing an active crime scene. The ability to take critical measurements from your photographs after the fact is highly valuable insurance. When the camera-to-subject angle is not perpendicular, the effects of perspective come into play. Edges are no longer parallel. Squares do not have four 90° corners, they become trapezoidal in shape. The following information is presented to allow you to confirm your photographs are perpendicular to the image plane. If the photographs are not at right angles, we explain here how to modify them.

Product Review: Full Spectrum Imaging System

TOO MANY TIMES WHEN PROCESSING EVIDENCE, we crime scene investigators come to a fork in the road and ask ourselves: Do we process for DNA, or do we process for latent prints? Once we contemplate which process would be best, we hope that we made the most logical decision for catching our suspect.
