Nah don't buy it.
A 80 year old man likely on long term libido reducing medication after his heart surgery 7 years prior and with ongoing health issues risked shipping 'thousands' of CSA images (presumably these are for sexual gratification right?) across the world into a small flat he shared with his son. The boxes sat in the small flat untouched for 2 years and then coincidentally the son who had recently been cut off financially after he stopped getting an allowance from his father, 'accidentally' finds all this while innocently going though his father's things looking for an old mobile phone to give to his girlfriend's father?
Jnr apparently gave up his life to move abroad to be his father's carer who he lived on the other side of the US from before, but didn't go with him to the US when he was emergency evacuated. Obviously made no attempt to pack up their tiny flat and return to the US to help care for his father, in what could be his last days, if he found this phone two months after his father had left and that wasn't via packing up. It was to give his father's property to his girlfriend's father!
I wonder if he's thinking the investigation won't be complete before Snr carks it or knows he's not medically fit to be questioned due to brain injury from his stroke?
Very convenient for someone who needs cash to come across this due to the media interest it would generate, and even more convenient for a nasty story about a father dying having been refused the opportunity to make peace with his very famous daughter, or ever meeting his grandchildren, to be given a very different spin.
