Abstract :

Physical evidence obtained at crime scene is important basic evidence in forensic science. In such examination along with classical methods, instrumental analysis plays a major role. Very few studies have been performed for cardboard comparison as physical evidence with reference to forensic examination. Examination and comparison of cardboard found in murder case was successfully performed using thermal methods of analysis. The results were also matched with control samples. The analysis is found to be helpful in identification and linking of physical evidences at crime scene. The results obtained from the simultaneous thermal analysis of cardboard seized at crime scene and company office showed that all the three layers in cardboard show similar thermal properties and differences found in the thermal properties were due to their treatment in making originating from binder in cardboard making. The adhesive material used in preparation of corrugated card board box results in exothermic degradation peak while endothermic peak was observed for corrugated card board box without adhesive material. The differences in results are found out with help of control sample as well as simulated study.
