Abstract
Present research is an attempt to study the lifespan of the bloodstains on different soil in different temperature. India is a subcontinent, which has all type of vegetation and climate hence, it is necessary to know the lifespan of bloodstain spilled during a violent crime on land. The land can be any type viz, wetland, dryland, sand dune etc. Current study has been conducted by simulating the three different temperatures on 5 different types of soils collected from varied part of the state of Karnataka in India. The findings of the study lead us to the understanding of lifespan especially with blood grouping, blood stain exposed to three different temperatures viz, room, cold and heat and observation period was every 5th day. It has been found that the best evidence retraction temperature is cold irrespective of soil type and when it comes to the best soil type for retraction of blood stain was sand and agriculture soil which gave the best result than any other soil respectively.
