I personally have’t meet Frederick. I was just 4 years old when I last met him.
According to my aunt (Frederick’s sister): He went to jail for murder. 6 years in jail. After he got released he visited my aunt and told her that he is going to be looking for jobs. He haven’t been seen for 4 or 5 years after the visit.
My aunt heard from somebody that they have seen him in Baclaran.
