Sorry, but I do not buy that part of the story. I am sure that this local radio station has got something wrong. It would be against all the teaching of the WTS for the parents to "disown" the lad because he was forcibly transfused. It seems that things were heated at the hospital and angry words may have been uttered that were misunderstood ?
Look at the title, it's in Ghana. Members of christian religions in these kinds of countries always seem to take it to extremes that are considered a bit too much to westerners. The culture is different & they tend to mix watchtowerism with their own innate brand of craziness.
