The present study identified 12 CpG sites from a collection of 476,366 CpG sites based on the following criteria: (a) CpG sites were retained if the Pearson correlation coefficient between the methylation values and the chronological age of the individual is greater than 0.85, and (b) if the mutual correlation coefficient between a pair of selected CpG sites is greater than 0.15, only one of them is retained. The identified CpG sites are associated with genes FHL2, ELOVL2, TRIM59, PCDHB1, KLF14, C1orf132, ACSS3, and CCDC102B. To ensure that the predictive accuracy is intrinsic to the selected CpG sites and not model dependent, the identified CpG sites were passed to three different Neural network models. All models achieved comparable accuracy across diverse populations, genders, and health conditions. The model's accuracy and reliability were validated through age predictions on independent datasets. By utilizing a minimal set of CpG sites, this approach offers a robust and efficient solution for forensic age estimation, significantly enhancing the precision and reliability of forensic investigations.</p>","PeriodicalId":12449,"journal":{"name":"Forensic Science, Medicine and Pathology","volume":" ","pages":"1145-1162"},"PeriodicalIF":1.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143630315","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 forensic pathologist initially concluded that the cause of death was asphyxia and haemorrhagic syndrome. Furthermore, due to the nature of some wounds resembling stab wounds, as well as facial injuries and marks consistent with gripping, the death was initially considered a possible homicide rather than attributing it to dog bites. Following these findings, the investigation took a drastic turn, resulting in the arrest of the witness. Three years later, our team was consulted for a second opinion. Reviewing the medical records confirmed dissection of both carotid and vertebral arteries without complete section, and fractures of cervical transverse processes, with the left and right vertebral arteries occluded by a bone fragment as seen on a CT scan from the emergency department. The second forensic expert supported the conclusion that the cervical injuries were consistent with dog bites, particularly due to the torn appearance of the muscle masses and soft tissue avulsion. Additionally, the vascular dissections and cervical fractures were attributed to hyperextension and/or compression of the neck, consistent with the dynamics of a dog attack involving shaking or grabbing the neck. Similar types of injuries have been documented in the scientific literature in cases of dog attacks. Furthermore, instances of wounds resembling stab wounds following dog bites have also been reported. The experts conclude that death was secondary to cerebral anoxia resulting from multiple dissections of neck vessels, aggravated by blood spoliation and asphyxia related to the laryngeal wound.

Chronic alcoholics may also stop drinking days or weeks before death, precipitating a terminal ketoacidotic state, of which beta-hydroxybutyrate (BHB) is the principal ketoacid.
