A bone marrow transplant made Chris Long, a resident of Nevada, a real chimera: the genetic composition of his blood has undergone a complete change. The donor was a German citizen. The operation was forced due to acute myeloid leukemia.
The police seriously wondered how to investigate cases in the event of such changes in citizens. At the moment, there is no previous Chris: instead, a completely different person.
The operation itself took place four years ago, the first changes became noticeable three weeks after it. After some time, all the DNA underwent changes: it became the same as that of a German donor.
According to some reports, Chris childrens, are likely to be similar to the man from Germany, rather than at him. Long’s body mixed a few different DNAs. Doctors call a man a chimera.
Interestingly, forensic specialists have real problems with bone marrow transplants. In 2004, DNA analysis from a fresh crime scene led the police to a man who had long been in prison.
It turned out that this prisoner previously had a bone marrow transplant from his brother, who turned out to be the same criminal. Fortunately, the forensics figured out this case and sentenced his brother to prison.
