Query: Very sad

The very disturbing true story of a woman who literally abused her adopted 3 1/2 year old son to death in 1965 and finally went to trial and was convicted 22 years later. Her husband and most of her large extended family covered for her. People who knew that little Dennis had been habitually beaten and otherwise abused mostly would not speak up. Even the first responder doctor and policeman soft-pedaled and failed to push the for the truth. Then there was the woman's brother who was an officer in the local police department who reportedly said he would protect his sister at all costs. And then there were missing documents... Siegel is a great story teller, but this book is not for the thin skinned reader due to the explicit descriptions of the abuse (the only reason for the four stars).
