Dumping after homicide using setting in concrete and/or sealing with bricks--six case reports

Homicide with subsequent hiding of the body using setting in concrete or sealing with bricks are rarely seen forensic cases. The article describes the circumstances and findings of six cases in which bodies were encased with concrete and/or bricks. In all cases, the offenders were male, in one case together with his wife and--except for one case--the victims were related to the offender. The causes of death were heterogeneous (suffocation, blunt force, shot) and the motive mainly domestic quarrel. Setting corpses in concrete and/or sealing with bricks does not prevent smell, slows decomposition and therefore complicates the estimation of the post mortem interval.     

Solid-phase microextraction for the determination of cocaine and cocaethylene in human hair by gas chromatography-mass spectrometry

A method for the simultaneous determination of cocaine (COC) and cocaethylene (CE) in human hair was developed, using solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS) as analytical technique to identify and quantify the drugs. Selected ion monitoring (SIM) mode was used to obtain higher sensitivity. The deuterated-labeled analogues were used as internal standards. The detector response was linear for the drugs studied over the range 0.4-15 ng/mg, with correlation coefficients higher than 0.995. The coefficients of variation oscillated between 0.65% and 14.18% and the accuracy was in the range from 0.73% to 11.20%. The limits of quantitation and detection were found to be acceptable. Finally, this method was applied to 15 hair samples from cocaine users, obtaining positive results in all cases. The mean concentrations were 5.39 ng/mg (range: 0.43-8.98 ng/mg) for cocaine and 1.11 ng/mg (range: 0.42-2.23 ng/mg) for cocaethylene.     

Do ideological and political motives really matter in? the?public choice of local services management? Evidence from urban water services in Spain

This paper studies the influence of ideology and political motives on the choice of management for urban water services. Our contribution is two-fold. Firstly, we use a considerably more detailed set of variables to represent ideological and political motives than previous research. Secondly, the variables that explain local politicians’ decisions are observed at the time decision-making occurs, rather than at a later date. Beyond pragmatic reasons, we find that ideological and political motives also matter when explaining decisions regarding the management of water services. Furthermore, considering the time dimension of decision-making noticeably improves the explanatory power of our model.     

New Executives from Inside or Outside? The Effect of Executive Replacement on Organizational Change

This article investigates how executive succession influences the comprehensiveness of structural changes pursued by public organizations. Executive successions are important events for organizations that provide salient opportunities for introducing organizational change, yet little research has analyzed this relationship. The author argues that the less familiarity a new executive has with the organization and the field in which it works, the more likely it is that comprehensive organizational change will take place. Empirical results from quantitative analyses of executive succession events in Danish municipalities from 1984 to 2000 confirm this. Interestingly, the degree to which new practices are legitimized moderates the findings. Inside successors are more likely to conduct comprehensive structural changes after new practices receive normative and regulatory legitimacy. The article contributes to the literature on executive succession by highlighting how it is an antecedent to different types of organizational change. Contributions to practitioner and public management research are discussed.     

Negotiating Urban Space: The Challenge of Political Steering in Market‐ and Network‐oriented Urban Planning

This article examines challenges related to the political steering of New Public Management‐inspired planning practices in Norway and asks if local politicians have sufficient and adequate instruments to hand, and if they are willing and have the knowledge to use them. The discussion is based upon a broad survey of the 145 largest municipalities and qualitative interviews in the three largest cities. It is found that local politicians do not lack steering instruments, as the different managerial practices represent a spectrum of suitable tools for giving direction to urban development. However, the data indicate that local politicians do not utilise the full steering potential of the instruments due to lack of knowledge and will. These findings contribute to the discussion of the strategic steering role of local politicians.     

Morphologic patterns of lip prints in a portuguese population: a preliminary analysis

Lip prints are thought to have the ability to distinguish individuals and, hence, have a potential use in human identification purposes. However, questions remain regarding their utility for sex determination. This study aimed to classify lip prints for different individuals in a Portuguese population and to determine whether sex differences exist. Lip prints of 25 females and 25 males were obtained using dark-colored lipstick and cellophane tape. Lip prints were analyzed using a magnifying lens and classified according to the Suzuki and Tsuchihashi classification. A Type II pattern was found to be most common. A comparison of lip-print patterns between males and females showed results with a statistically significant difference: Type III pattern was most common in males, and a Type II pattern in females. This study corroborates the hypothesis that lip prints are able to distinguish individuals and may be useful in sex determination.     

Assessment of forensic findings when alternative explanations have different likelihoods—“Blame-the-brother”-syndrome

Assessment of forensic findings with likelihood ratios is for several cases straightforward, but there are a number of situations where contemplation of the alternative explanation to the evidence needs consideration, in particular when it comes to the reporting of the evidentiary strength. The likelihood ratio approach cannot be directly applied to cases where the proposition alternative to the forwarded one is a set of multiple propositions with different likelihoods and different prior probabilities. Here we present a general framework based on the Bayes' factor as the quantitative measure of evidentiary strength from which it can be deduced whether the direct application of a likelihood ratio is reasonable or not. The framework is applied on DNA evidence in forms of an extension to previously published work. With the help of a scale of conclusions we provide a solution to the problem of communicating to the court the evidentiary strength of a DNA match when a close relative to the suspect has a non-negligible prior probability of being the source of the DNA.     

Palatal rugae pattern in a Portuguese population: a preliminary analysis

Palatal rugae have been related with specific racial groups and are said to be useful in sex discrimination. This work aimed to characterize the palatal rugae patterns in a Portuguese population. Fifty plaster casts were examined for first and third rugae shape evaluation; shape, frequency, and association with sex were studied. In females, the most prevalent first rugae were the straight type on the right and the curve type on the left; in males, the straight type was the most prevalent on both sides. The most frequent third rugae type was sinuous on both sides, in both sexes. No significant sexual dimorphism in rugae shape was found (p > 0.05). When comparing these results with those from other investigations, it was clear that a particular rugae pattern could be established for different ethnic groups. However, the small sample size justifies further work in larger samples to validate these findings.     

Undiagnosed, untreated acute promyelocytic leukemia presenting as a suspicious sudden death

Acute promyelocytic leukemia (APL) is a subtype of acute myelogenous leukemia frequently associated with clotting abnormalities and severe hemorrhagic diathesis. The disease is associated with a high incidence of early fatal hemorrhage. We report the sudden death of a 40-year-old male without significant medical history in which foul play had been initially suspected. A thorough postmortem investigation performed on the decedent lead to the diagnosis of APL. Cause of death was a cerebellar hematoma. Underlying APL should be considered in the differential diagnosis when unexplained bleeding is encountered in a decedent. This case emphasizes the value of routinely collecting bone marrow during an autopsy to enable accurate testing and diagnosis.
