IF
HE DELIBERATELY LESSENED OXYGEN TO HER BRAIN
and
HE DELIBERATELY PREVENTED AN MRI,
that turkey is the enemy and needs tried, convicted and sentenced.
Terri had a guardian ad litem; it wasn't up to Michael to determine whether Terri had an MRI or not.
And he didn't strangle her, for goodness sake. She had a heart attack, brought on by bulimia. She's been examined by a gazillion doctors.
And IF both of those happened, DELIBERATELY, the judge and/or LE would have known, proven and prosecuted him for it.
