Child Abuse-Related Homicides in New Mexico: A 6-year Retrospective Review

Abstract:  We retrospectively reviewed autopsy records at a statewide medical examiner's office in order to identify and characterize deaths due to child abuse. In a 6-year period in New Mexico, the medical examiner investigated 45 deaths determined to be child abuse-related. Decedents were predominantly male (68.9%), Hispanic White (53.3%), and all were 5 years of age or younger, with a median age of 1 year. Head injuries were the most common cause of death (44.4%), followed by battered baby syndrome (15.6%). Relatives were involved as alleged perpetrators in 80% of the cases, with the father most often implicated (36.1% of cases), and 88.9% of child abuse injuries resulting in death occurred in the family's residence. Toxicology was positive in 26.7% of cases, but only two cases had substances of abuse present. Information on risk factors such as prematurity, parental age, and history of abuse was also collected.     

Police psychology: The influence of Daubert and its progeny

In the current legal atmosphere, any practicing professionals, including police psychologists, may expect to have their decisions challenged in court. If such a challenge is not met, it may have a disastrous financial and reputational impact for both the psychologist (and other expert consultant) and the employer or contractor by whom the psychologist has been retained. The rules for expert witness qualification throughout the nation have been very strongly effected by the introduction of the Federal Rules of Evidence in 1975 and subsequent case law, particularly theDaubert, Joiner, andKumho Tire Supreme Court decisions. This article examines the history of the development of theDaubert Standard and proposes principles for potential expert witnesses in order to minimize the likelihood of aversive consequences, such as disqualification or malpractice accusations.

The use of DNA statistics in criminal trials

In a number of recent cases in the UK, convictions have been quashed by the Court of Appeal on the grounds that the jury had been misdirected as to the factual significance of random occurrence statistics. The mathematical basis on which those statistics are calculated was reviewed and recent appeal cases involving DNA evidence in the UK and the US were examined. It was found that a widespread misconception exists regarding the random occurrence ratio and its relationship with probability of guilt. It is in fact impossible to relate the two with any degree of accuracy without consideration of social and demographic factors particular to a case as well as any non-DNA evidence obtained.     

The onset of adult offending: A neglected dimension of the criminal career

The conventional wisdom in criminology is that adult onset of offending is a rare event. Closer examination of the extant literature that use official records, however, reveals that an average of 50 percent of adult offenders initiate offending at age eighteen or older. Although criminological research has investigated late onset offending in adolescence, there is little research on adult onset offending and the correlates of adult offending. Using police contact and interview data from the 1942 and 1949 birth cohort data from Racine, WI, this study investigated the correlates of crime for adult onset and persistent offenders. The results show that employment is the only correlate to affect the probability of adult offending differently for previously delinquent and nondelinquent offenders. This article concludes by highlighting the neglect of research on adult offenders, specifically the large percentage of adult onset offenders, and calling for more research on this topic.     

Courts and health policy: judicial policy making and publicly funded health care in Canada

The 1982 Canadian Charter of Rights and Freedoms provided political actors with the opportunity to make rights-based challenges to public policy decisions. Two challenges launched by providers and consumers of health care illuminate the impact of judicial review on health care policy and the institutional capacity of courts to formulate policy in this field. The significant impact of rights-based claims on cross-jurisdictional policy differences in a federal regime is noted.     

Interrogation of short tandem repeats using fluorescent probes and melting curve analysis: A step towards rapid DNA identity screening

Current forensic DNA profiling methods rely on the analysis of samples at specialised laboratories with an average turnaround time of several days. The ability to rapidly determine a partial profile of short tandem repeats at the point-of-arrest would be of great benefit to police forces around the world, for example enabling a suspect to be rapidly included or excluded from an investigation. We have developed a homogeneous PCR method for the interrogation of STR loci utilising fluorescent oligonucleotide probes and melting curve analysis. Alleles of the D18S51, TH01 and D8S1179 loci were differentiated and identified on the basis of target length and probe melting temperature. Assay performance was evaluated by comparing melting peak data with the AmpFlSTR^® SGM Plus^® system. The method is compatible with direct analysis of unpurified buccal swab samples, enabling a partial STR profile to be generated within 1 h.
