However, most of this documentation is based on single-case examples. While this information is valuable, it does not provide an in-depth understanding of scavenger behavior in a single environment. Mouse scavenging data, in particular, lack larger sample sizes and data representing the full duration of scavenging activity. In documented cases, mice scavenge primarily the hands, the feet, and the head without significant progression into the rest of the body. At the Forensic Investigation Research Station in Whitewater, Colorado, deer mice (Peromyscus maniculatus group) scavenged tissue from 11 human donors. Motion activated game cameras and regular field photography documented scavenging progression and deer mouse behavior. Deer mice generally showed a preference for skin and fat, rarely consuming enough muscle to expose bone. The most scavenged sections of the body were the limbs and deer mice generally ignored the hands, the feet, and the head, unlike previous documentation. In a few cases, deer mice consumed tissue on the limbs in a distinct trail pattern. Most of the scavenging began in spring. This sample greatly expands on the existing documentation of mice overall and contributes much needed data on the progression of scavenging. Scavengers can have a significant impact on a death scene, so detailed documentation of different scavengers in a variety of environments can prove useful in the investigation process.","PeriodicalId":15743,"journal":{"name":"Journal of forensic sciences","volume":"70 1","pages":"258-263"},"PeriodicalIF":1.5,"publicationDate":"2024-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142570867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we developed a method using droplet digital polymerase chain reaction (ddPCR) to simultaneously identify and quantitatively detect human, dog, and cat DNA in mixed samples. HLA-DRA was chosen as a human-specific marker, OR6D7 as a dog-specific marker, and FLAI-K as a cat-specific marker. The species specificity of each target was confirmed using 14 control DNA samples from 11 mammals and 3 birds. Sensitivity tests determined the limit of detection to be 0.0008 ng/μL for human DNA and 0.00061 ng/μL for dog and cat DNA. In the mixture test, each DNA sample was independently and accurately detected in samples containing trace amounts of all three types of DNA. This study demonstrated the effectiveness of applying ddPCR to forensic case samples from dog- and cat-related incidents. We have presented a reliable method for the accurate identification and quantification of human, dog, and cat DNA simultaneously, offering possibilities for advancements in forensic DNA analysis and related fields.","PeriodicalId":15743,"journal":{"name":"Journal of forensic sciences","volume":"70 1","pages":"38-48"},"PeriodicalIF":1.5,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142549761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The innominate is widely accepted to be the most sexually dimorphic skeletal element. The Diagnose Sexuelle Probabiliste (DSP) method, which uses 10 measurements of the innominate, was introduced in 2005 and updated as DSP2 in 2017. While DSP2 has been reported to have high classification accuracy rates in studies of South American and European populations, the method has not been widely tested in US samples, and few US practitioners incorporate this method into their casework. The goal of this study was to test the reliability and accuracy of DSP2 using a large, modern sample from the US (n = 174). Two observers, blinded from demographic information associated with each specimen, collected the DSP2 metrics. Intra- and interobserver error analyses showed acceptable levels of agreement for all measurements, except for IIMT. Classification accuracies exceeded 95%, with minimal sex bias, for both observers and using various measurement combinations; however, an inclusivity sex bias occurred with more males reaching the 0.95 posterior probability threshold required by DSP2 to provide a sex classification estimate. Based on its high accuracy, forensic anthropologists in the US may consider incorporating DSP2 into their casework, although we recommend excluding IIMT and using SPU with caution. Additional methods will continue to be needed when the posterior probability threshold is not reached.","PeriodicalId":15743,"journal":{"name":"Journal of forensic sciences","volume":"70 1","pages":"249-257"},"PeriodicalIF":1.5,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11693525/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142515392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sample shared common characteristics with juvenile parricide offenders overall in that most of them killed one parent, were victims of chronic child abuse, had one or more psychiatric diagnoses (PTSD was most prevalent), used a firearm, and committed the killings at the family home. Unexpectedly, YPOs who were child abuse victims were not more likely to engage in undoing behaviors than non-abused youth, and over half of the youth with undoing behaviors had elevated psychopathy levels. Three-quarters of youth who moved victim bodies following the murders had elevated psychopathy levels. Similarly, all three youth who transported bodies away from the crime scene had elevated psychopathy levels and conduct disorder. None of the youth with psychotic symptoms engaged in undoing behaviors, altered victim bodies, moved bodies either within or away from the home, or had an elevated degree of psychopathy; they also most often killed using bladed weapons, whereas the nonpsychotic youth usually used firearms. Studies examining the influence of mental illness and psychopathy level on parricidal behaviors by youth are scarce, and to our knowledge this is the largest study to date investigating this area.","PeriodicalId":15743,"journal":{"name":"Journal of forensic sciences","volume":"70 1","pages":"186-199"},"PeriodicalIF":1.5,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11693520/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142515391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method involves examining (latent) fingermarks, typically captured as two-dimensional (2D) images, and comparing them with known inked impressions or scans. The comparisons focus on general patterns, the location and orientation of minutiae, and additional characteristics like scars or pores. However, this common process overlooks other potentially valuable factors, such as handedness, biological sex, and the time since deposition, which could provide crucial investigative leads, especially in cases with partial or unclear ridge patterns. This study explored the potential of three-dimensional (3D) optical profilometry (OP) to observe changes in fingermarks ridge height and volume over 7 days while considering hand dominance and biological sex. The results indicated that all the assessed 3D metrics were generally consistent in detecting the effects of sex and handedness, mostly noticeable on aged fingermarks. Specifically, females and impressions from their non-dominant hand exhibited higher values. Additionally, the influence of time was evident, with fresh fingermarks showing significantly larger ridges in terms of height and volume. These findings suggest that 3D OP can enhance the probative value of fingermarks by inferring additional characteristics such as sex, handedness, and the age of the impression. These activity-level propositions could provide useful information in cases where only partial or poor-quality fingermarks are recovered, providing new data dimensions that could lead to more comprehensive forensic examinations.","PeriodicalId":15743,"journal":{"name":"Journal of forensic sciences","volume":"70 1","pages":"284-297"},"PeriodicalIF":1.5,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142484304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though previous theories of crime and empirical research support a relationship among future time orientation, criminal thinking, and illegal behaviors, there is disagreement in the literature about how to operationalize the multidimensional construct of future time orientation. The primary aim of this pre-registered survey study was to measure multiple components of future time orientation to better understand the relationship with criminality-related outcomes. Participants were 248 undergraduate college students. Survey materials included a measure of impulsivity (Barratt Impulsiveness Scale-11), self-control (Brief Self-Control Scale), delay discounting (Monetary Choice Questionnaire), and Carstensen's Future Time Perspective Scale. Participants also completed two measures of criminal thinking style (the Texas Christian University Criminal Thinking Scale, the Criminogenic Cognitions Scale) and an illegal behaviors checklist. Bivariate results demonstrated a negative relationship between future time orientation (i.e., low impulsivity, high self-control, high future time perspective) and criminal thinking style. The relationship between delay discounting and criminal thinking was in the hypothesized direction but failed to reach statistical significance. Multiple regression analyses indicated that the measure of self-control had the most consistent and incrementally significant relationship with both criminal thinking style and illegal behaviors. Theoretical and practical implications of the results are discussed along with study limitations and future directions.","PeriodicalId":15743,"journal":{"name":"Journal of forensic sciences","volume":"70 1","pages":"200-214"},"PeriodicalIF":1.5,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142484305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
