The time of death differs by two months, so much of the previous investigation can be overturned.
Although it seems a bit far-fetched, the reality is such, when dealing with decomposed bodies, forensic doctors always face various possibilities of failure. It's not just a matter of a two-month discrepancy, there are plenty of cases where the difference has been two years.
The decomposition changes of a biological body in different environments are not so easy to judge. Not to mention the physicochemical indicators, even if you place a child over three years old in front of a doctor, he wouldn't be a hundred percent sure about the child's age, let alone the large margin of error in indicators like height and weight. Even if blood tests are allowed, even if bone growth lines are checked, there's still the possibility of age overestimation.
