According to the search results, there are several theories about what happened to Ajits body in the movie Jaane Jaan, but there is no definitive answer. Naren, one of the main characters, is believed to have disposed of the body in a way that would not create any suspicion in the town. One theory suggests that Naren chopped the body and spread it across the forest, which surrounded the hilly town, where wild animals could have helped the body and any evidence disappear. Another theory suggests that Naren could have dumped the body near his home or the police station, since the fake Ajit’s body has already been found, and nobody will look for the actual corpse. A third theory suggests that Naren exchanged Ajits body with another dead body and kept the comb used by the second person in the hotel so that the DNA would match, and the plan would work out well for him. However, the movies creators have left the ending open, and there is no definitive answer to what happened to Ajits body.
