If memory serves, MacDonald did not get the death penalty - for the first degree murder of his littlest child - the other two were 2nd degree murder - because the death penalty at that time was not in force. At the time of his conviction, 9 years after the crime. (By the way - the first court who heard the evidence - the military court - found there was not enough evidence to court martial MacDonald. But, through outstanding persistence by the grandfather of those kids, the father of Collette, and by excellent investigative work and attorney work - MacDonald was convicted and has not been freed on parole after many attempts. Oh, MacDonald sued and won a lawsuit for $350,000 against Collette’s father I think - or his attorney. But they counter sued for wrongful death and won most or all of that amount back!!!
I think you are right. Wasn’t it finally decided he killed the baby for wetting the bed and the others to cover it up?
