Considering Crippen

Recent press reports have indicated the 1910 conviction of Dr Crippen for the murder of his wife, Cora, may have been in error.

This seems to me a hasty conclusion which does not consider the following:

The "proof" rests on a few assumptions.

1. that the slide is indeed the proper one .( Chain of custody was not as carefully kept in 1910 as might be desired)

2. That the woman known as Cora Crippen was biologically related to the individuals who gave the DNA samples.
(Keeping adoptions secret was very common in 1910-many adoptees in that period never knew their biological heritage differed from that of their parents.)

3, That the woman married to Dr Crippen had not assumed another's identity. Cora Crippen was known to change her name - (She began life as Kunegunde Mackatmotski)

4.. The rare chimera possibility.

All that had been definitely proven is that slide labeled as that of Cora Crippen does not match the donated samples of individuals who are believed to be biological relatives.
