What are some famous cases of munchausen by proxy syndrome?

Marybeth Tinning in upstate New York. She had one of her kids die of natural causes... then she offed her others till she ran out. She then had some more... and offed them too. Having a shortage of kids to kill... she adopted one... and killed it. Ran a couple more out the chute and into the grave. I think her total was 8 or 9 dead children. The authorities had suspicions, but no proof, and got it too late to save any of the youngins. Needless to say, she has been denied parole to date, and her husband stands by her still... some 30 or 40 years later??? I have a MBP ex who put 2 of my 3 in the hospital. I caught it and fought her attempts to medically abuse my children... but she did an awful lot... with the courts and professionals watching... and almost got away with it. It's an illness that defies any sense of logic to the point that most people just can't get their heads around it. Most cases go undetected... fame only comes with a failure.
