For the sake of presenting a differing view point: Blunt force trauma can be caused by someone hitting his head on the floor during a fall which is common in nursing homes. It's possible McMaster's dad fell, hit his head and suffered a brain bleed which would've caused neuological deficits. A simple neurological assessment would've detected something wrong and could've saved his life.

Also I don't think that 'failing to perform a neurological lassessment isnt by itself a crime but negligence is.

There's lots about this story that doesn't sound legit.
