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.
There sure seem to be some stark differences of opinion and of the record.
Someone should have gotten fairmindedly to the bottom of it long ago, imho.
