I am sure PJ is not RJ ! Because when he remembers the scene of discovering his wife and his daughter dead, he is always surprised and at the same time terrified, is just his memory, nobody knows it, nobody can read his mind so he don't have to act in his imagination. The only theory which can be approved is that PJ has serious mental problems, like multiple personality. But it can't be possible, it would be noticed and also his thinking would be affected. Don't you see how many cases ended with charities made ​​by him? He is a good man !!!
