Forensic gait pattern analysis is the scientific and systematic evaluation of different gait characteristics involved in gait pattern left at scene of occurrence during crime by criminal, victim, or any other person and it is used as a parameter because of their individualistic nature to eliminate suspect list as it contribute in personal identification of any suspect related to the crime scene, meanwhile helps investigating officer to make a criminal profile. Gait pattern is the way of walking or a manner of movement of lower limbs during locomotion of any person and it constitutes some feature during development of walking pattern like step length, step width, step angle, foot angle, etc. Which is somehow individualistic? And gait pattern is countered as a evidence in number of crime scene robbery, hit and run, homicides, kidnapping, etc. The present study expecting probable correlation between four gait characteristics which is step length, step width, step angle and foot angle of person and stature in both male and female separately. And will be developed as a forensic tool which provide us relevant information like stature, gender of the person and help to generate criminal profile.

Pregnancy and the postpartum period carry high risk of thromboembolic phenomenon which increases manifold postpartaly. Multiple predisposing risk factors, usually acting in combination, add up to this risk. All three of the Virchow’s triad conditions predisposing to vascular thrombosis, i.e, endothelial injury, venous stasis and hypercoagulability, are present in pregnancy. The deaths caused by pulmonary embolism may become the subject of medicolegal investigation due a sudden and unexpected fatal outcome. A thorough dissection, documentation and ancillary investigations pertaining to pulmonary emboli are important components of evaluating such fatalities. The investigation requires a dependable protocol that should include a proper evaluation of the timing of the embolus along with the residual and other thrombi, whenever discovered. Because of the pathophysiology and propagation of thrombus over a range of time period, one may see a broad histological range of thrombosis and organization. The present case pertains to the sudden death of a young female in the postpartum period who suffered a massive pulmonary embolism about 6 weeks after delivery. An extensive dissection of the lower limbs showed multiple deep venous thrombi in the calf and femoral regions while moderate to large coiled emboli were found in the pulmonary arterial vasculature. An additional histological dating of the thrombi as well as pulmonary embolus was performed that helped in elucidating the time range of their development.

A forensic medical examination when committing depraved acts is carried out only in cases where there are any changes on the body of the victims, according to which it is possible to establish the fact of such actions. An examination may also be carried out in respect of material evidence. At the same time, the jurisdiction of a forensic medical expert includes the detection of traces and changes on the body of victims, as well as the mechanisms of their formation. The fact of depraved actions is established by the court and the investigating authorities.

Disaster may be caused by natural events such as severe flooding, earthquake or volcanic eruptions.it can also be due to human activities such as mishaps involving mass transport by Land Sea, air and other causes include war, boundary disputes. Identification of individual victims by devital means is one of the most reliable methods. In case of severe disintegration visual recognition of facial features and finger prints are often impossible due to soft tissue destruction. This situation necessitates the use of the hard calcified tissue such as human dentition and jaws, pelvis and skull.
