Generally find this programme to be gripping, if quite depressing (understandably) due to the subject matter - and how many murderers and/or rapists tended to get away with their crimes pre-dna testing.
Anyway, was quite bemused in episode 15 (Finding Suzanne) to see the "medical examiner" writing up in their report of the investigation about the body and writing skelatan instead of skeleton. Surely someone checks this type of thiing? It tickled us.
