A Novel Method for Removing a Spinal Cord with Attached Cervical Ganglia from a Pediatric Decedent

A diagnosis of child abuse is dependent on a comprehensive and accurate assessment of injury in the context of a thorough investigation. However, signatures of trauma are often subtle and interpretation can be very difficult. Recently, researchers have refocused their attention from the head to the neck in search of traumatic signatures of abusive head trauma. HCIFS has developed a technique to remove the cervical spinal cord with the ganglia attached that is less destructive and more time and cost efficient than alternative methods previously published. Once removed, the dorsal nerve roots and ganglia are evaluated for the presence of hemorrhage. The authors performed a small pilot study using the novel method to evaluate 20 decedents with a history of blunt force trauma and eight without a traumatic history. Fifteen of the traumatic deaths and two of the nontraumatic deaths were found to have dorsal nerve root and/or ganglia hemorrhage.

Adhesive tape on the face--criminalistic aspects

Under forensic differential diagnostic aspects postmortem findings of adhesive tape in the face suggest either suicide, an autoerotic accident or homicide, in which case the adhesive tape could have been used for sealing the mouth or as a means to commit the homicide itself. 9 autopsy cases are described as examples with this constellation and discussed under criminological aspects.     

钝力性心脏外伤38例尸检病理学研究

本文研究表明钝力作为原始致伤因素作用于胸部通过压、拉、剪切、旋转等可引起钝力性心脏外伤包括心脏震荡、心脏挫裂伤、心脏玻裂、心脏断离等原发性心脏外伤和继发性乃至迟发性心脏外伤，诸如外伤性心脏炎、冠脉血管炎、血栓形成、外伤性心肌梗塞、外伤性冠状动脉瘤、外伤性室壁瘤、迟发性外伤性心脏破裂等。致命性的心脏震荡，除急性冠循环障碍和心失常外，还可有心脏传导系统和神经组织损伤，尤其心肌肌膜爆裂（ｓａｒｃｏｌｅｍｍａｂｕｒｓｔ）及相应的原纤维膨出畸形变可以作为心脏震荡性外伤的形态学指证。外伤性心肌梗塞和迟发性外伤性心脏破裂以突然发生在外伤后的一定间隔期为特征，应予特殊注意．     

Forensic integrity verification of video recordings based on MTS files

Digital video is used in criminal trials as evidence with legal responsibility because video content vividly depicts events occurring at a crime scene. However, using sophisticated video editing software, assailants can easily manipulate visible clues for their own benefit. Therefore, the integrity of digital video files acquired or submitted as evidence must be ensured. Forensic analysis of digital video is key to ensuring the integrity of links with individual cameras. In this study, we analyzed whether it is possible to ensure the integrity of MTS video files. Herein, we propose a method to verify the integrity of MTS files encoded by advanced video coding high definition (AVCHD), which is frequently used for video recording. To verify MTS file integrity, we propose five features. Codec information, picture timing, and camera manufacture/model are modified AVI and MP4-like format video verification features. Group of pictures and Universally Unique Identifier patterns were specifically developed for MTS streams. We analyzed the features of 44 standard files recorded using all recording options of seven cameras. We checked whether integrity can be validated on unmanipulated videos recorded in various environments. In addition, we considered whether manipulated MTS files edited in video editing software could be validated. Experimental results show that all unmanipulated and manipulated MTS files with known recording devices were discriminated only when all five features were checked. These results show that the proposed method verifies the integrity of MTS files, strengthening the validity of MTS file-based evidence in trials.     

The use of videotape to demonstrate the dynamics of bite marks

Traditionally, bite mark photographs have been used to study statically a dynamic event. With the advent of the compact video camcorder, odontologists can now document bite marks on video tape and, in some instances, with the model of the suspect's dentition, may be able to record the dynamics of a bite on human flesh. A review of two cases and equipment used is discussed.
