Introduction: Skull-face photograph superposition is one of the methods of identification. Digitally recorded and stored within the computer, the images of the skull and face could be superimposed on the monitor. The method requires cooperation among the anthropologist, odontologist, forensic pathologist and the computer technician so as to avoid objective and subjective errors in the identification. Case Outlines: We present two cases of positive identification by superimposition. In the first case, it was a 65 year-old male with several brain operations, thus surgical skull bonetrepanations could be seen as the irregularities on the forehead, and were used as the antropological identificational figure. In the second case, it was an 83 year-old female, whose positive identification was made according a photograph taken at least 26 years before death. Conclusion: Face identification by computerized superposition method is usefull in all cases where both the skull and the photograph of the missing person are present, and where other methods of identification have failed due to multiple reasons.

Calcium, as one of the main extracellular ions, maintains a key role in numerous biologic functions. For forensic purposes, it was analyzed mostly for estimation of postmortem interval (PMI). We have designed our experiment with the concept that the repetitive withdrawal of vitreous humor (VH) might clarify the postmortem metabolism of calcium in greater detail to estimate the PMI. Accordingly, 248 samples of VH from 31 autopsy cases were evaluated over three years; samples (0,1 mL of VH) were taken and analyzed at equal time intervals after death—every three hours until 24 h after death. Each sample was centrifuged and analyzed using the ARCHITECT C SYSTEM 8000. Moreover, functional relationship between PMI and calcium concentration was established: PMI (hours) = [Ca2+] × 13.696–7.843. Although the concentration of calcium in VH in the analyzed group increases with time, the coefficient of variation for the regression (CVreg = 46.8%) indicates that this correlation is not so strong, meaning that the level of predictiveness of calcium for estimation of time since death is poor when is not used in combination with other relevant substances. © 2020 Elsevier B.V.
