2 Pages back someone suggested that SH may not have had a good relationship with his father and this is why he was homeless. Through my research SH has a younger sister and brother (I can name them if allowed on here). He also has a lot of extended family members in the area. During this crisis I have not heard of one person who has stated to be a relative of his, unlike those proclaiming that CS is their Aunty, Sister, Cousin etc and kind and loving etc etc.
I doubt that SH could be a police informant, he has a rap sheet too long to be trusted. Plus he is clearly stupid beyond belief, as he has either left a long trail already or is covering for someone else.
If CS is a carer, perhaps she was looking after someone who was a sleep and so she snuck home for a while. Maybe things turned when she arrived to find mayhem.
I am curious to know more about DS, he seems to be very quiet now. We didnt even get a clip of him laying flowers yet.
