While most believe that it will no longer be able to establish the relationship indisputably, it is still possible to do so. Options are available, such as using what is known as DNA relationship detection, testing close relatives of the deceased, such as parents, grandparents, siblings and nephews, nephews, cousins, uncles and aunts, etc. Often, the results can determine whether or not the deceased was the father. In addition, there are also more direct options for obtaining samples from the deceased, and three of them are discussed here.
It is possible to take a sample of the alleged father if he has been dead for not more than a week. The sample should include a more robust fabric, such as a hair with the root or nail clippings. Both are preferable, and although they are more difficult to process than an oral swab, a competent laboratory should be able to handle it. DNA from these samples can be used to determine paternity, but be sure to get permission to take the samples first.
There may be a major problem if the alleged father has not only died but has also been committed. In this case, you will not be able to use a sample directly from the body and you will have to search for another indirect sample. The material in the novels may sound, but DNA samples can be taken from cigarette butts, drinking glasses and hair brushes, and it is as relevant for DNA comparison tests as oral swabs are. However, it has to be sufficient, and such samples tend to be quite small with too low a DNA yield to allow for a proper comparison. However, it is a viable possibility to consider.
When Exhumation is Necessary, you should use the services of someone with experience in this type of work, such as a forensic expert or a pathologist. When the body has been buried for a long time, and only bone remains are available, a bone sufficient to provide sufficient DNA for comparison should be taken. The best bone area is the femur neck or humerus, and a sample of 2 grams should be sufficient to provide the amount of DNA required by the analyst.
