Developmental validation of a novel lateral flow strip test for rapid identification of human blood (Rapid Stain Identification™-Blood)

Human blood is the body fluid most commonly encountered at crime scenes, and blood detection may aid investigators in reconstructing what occurred during a crime. In addition, blood detection can help determine which items of evidence should be processed for DNA-STR testing. Unfortunately, many common substances can cause red-brown stains that resemble blood. Furthermore, many current human blood detection methods are presumptive and prone to false positive results. Here, the developmental validation of a new blood identification test, Rapid Stain Identification™-Blood (RSID™-Blood), is described. RSID™-Blood utilizes two anti-glycophorin A (red blood cell membrane specific protein) monoclonal antibodies in a lateral flow strip test format to detect human blood. We present evidence demonstrating that this test is accurate, reproducible, easy to use, and highly specific for human blood. Importantly, RSID™-Blood does not cross-react with ferret, skunk, or primate blood and exhibits no high-dose hook effect. Also, we describe studies on the sensitivity, body fluid specificity, and species specificity of RSID™-Blood. In addition, we show that the test can detect blood from a variety of forensic exhibits prior to processing for DNA-STR analysis. In conclusion, we suggest that RSID™-Blood is effective and useful for the detection of human blood on forensic exhibits, and offers improved blood detection when compared to other currently used methods.     

Lasting rights and last rites: a case report

The contrast between legal and clinical perceptions of reality, characterized as discrete versus continuous in nature, generates dilemmas for both professions. Individuals in conflict with either system are especially vulnerable to the philosophical serrations at the interface between psychiatry and the law. A case example, which serves to magnify the gripping impact of these diverse and powerful institutions, raises various issues for examination and discussion.     

Implications of trombiculid mite bites: report of a case and submission of evidence in a murder trial

Bites of Trombiculid mites implicated a suspect during a homicide investigation. Clinical documentation of the bites, correlation with entomological studies, and submission of evidence at trial are reported. Insects that have a discrete geographic distribution and leave bites of a characteristic nature may have important forensic science implications.     

Judicial Perspectives on Family Drug Treatment Courts

Family Drug Treatment Courts are a specialized calendar or docket that operates within the juvenile dependency court. These courts provide the setting for a collaborative effort by the court and all the participants in the child protection system to come together in a non‐adversarial setting to determine the individual treatment needs of substance‐abusing parents whose children are under the jurisdiction of the dependency court. This article is intended to give judges and others a judicial perspective on FDTCs, and to offer some assistance for those who are operating or who are considering creating one.
