Use of nitrogen cryogun for separating duct tape and recovery of latent fingerprints with a powder suspension method

Duct tape is sometimes recovered as physical evidence in crimes. The purpose of this study was to determine the quality of latent prints on the adhesive and non-adhesive surfaces of duct tape samples that were separated using three methods. Three hundred donor fingerprint impressions were deposited on duct tape. Sections of duct tape were affixed to sections of cardboard and a fingerprint placed on the non-adhesive surface of the tape. A second layer of duct tape was prepared and a fingerprint placed on the adhesive side of the tape and then the tape was affixed to the piece of tape on the cardboard. After a 24-h period, the samples were separated using gradual force, liquid nitrogen applied with a cryogun and an adhesive neutralizer to separate the layers of tape. The recovered fingerprints were processed with a fingerprint powder suspension method. The recovered fingerprint images were evaluated and rated as +1, +2, or +3. The liquid nitrogen spray separation method yielded the highest number of +3 prints.     

The development of the comprehensive health assessment tool for young offenders within the secure estate

Health inequalities are high among offending groups. The comprehensive health assessment tool (CHAT) is a semi-structured assessment developed to provide a standardised approach to health screening for all young offenders admitted to the secure estate. The four sections of the CHAT (physical health, mental health, substance misuse and neurodisability) were evaluated within a two-phased study of male adolescents (aged 15–18?years) within a young offenders institution in the north-west of England. Within Phase 1, a consecutive sample of 127 new receptions was assessed using the physical health, mental health and substance misuse sections of the CHAT against a range of reference standard assessments. Phase 2 of the study evaluated the neurodisability section on 93 male adolescents against reference standard tools. The four sections of the CHAT demonstrated fair to good convergent validity when compared against reference standard tools in male offenders. The diagnostic accuracy rate was 76% for mental health, 63% for physical health, 83% for substance misuse and 53% for neurodisability when compared against reference standard assessment tools. The introduction of the CHAT offers the opportunity to enhance existing reception screening practices and create an integrated approach to the assessment of health needs across the secure estate.

Court improvement of foster care and adoption projects:Ncjfcj Survey Report

Officials from 48 states and the District of Columbia in 1994 accepted federal funding from the U.S. Department of Health and Human Services to help improve courts' handling of cases involving child abuse, neglect, foster care and adoption. Through a survey of participating states, members of the National Council of Juvenile and Family Court Judges have been analyzing common themes found in state Court Improvement of Foster Care and Adoption Projects. This article examines key survey results.     

Forensic entomology: application, education and research in Western Australia.

Forensic entomology as a science and a tool for investigation has had slow beginnings in Australia. A number of small animal decomposition trials have been recorded in the literature but mostly from an ecological rather than a forensic entomology perspective. In the last 20 years, a number of more forensically orientated field trials on small pigs and some fly developmental trials in the laboratory have been conducted but lack any replication. The following article was presented at an international seminar to detail the current research in forensic entomology, the applications of forensic entomology in scene of crime (SOC) and homicide investigations and the education of police and judiciary in the discipline of forensic entomology in Western Australia over the last 10 years.
