Had a friend whose child was most likely killed by the babysitters husband. The babysitter had left to pick up her own child from school and when she came back the babysitter was for all purposes gone. The boyfriend said the baby fell down the steps but doctors believe it was shaken baby syndrome.
When the doctors told my friend he was lucky he had family who could hold him back because he was going to kill the guy. His family was able to hold him back and calm him down but he was definitely seeing read and not thinking clearly at the time.
Courts never could prove it was the boyfriend so he never did get justice.
I can see why there is temporary insanity.
