DS1 left home over 2 years ago. Had been difficult, aggressive. Since then in and out of mental health hospitals and attempted suicide. Very troubled, in his 20s, bright but has lost direction big way.
Been back a couple of times since, totally unexpectedly and caused chaos. Younger DCs, mid teens, frightened of him. DS1 has threatened me - told his therapist about having violent fantasies towards me and written me very cruel and intimidating notes.
Today, out of the blue, met younger DC as DC was walking home from school. Told him he was living nearby - didn't say where exactly- and would DC like to live with him? DC was frightened and eventually managed to walk briskly away.
DH and I rang police - total indifference (and no call returned). They've been OK in the past, even fitting an alarm in the house and intervening in past episodes but on this occasion, as on the last unexpected visit from DS1, they couldn't care less.
I have to protect my younger DCs (and myself) and so I feel that the police should be speaking to DS1. They could find out where he's living - we know someone who is very likely to know but who, stupidly, has barred our no on his phone and so we can't speak with him (we expect that DS1 applied pressure on him so to do). I am so worried now, DS3 who came across DS1 today is visibly shaken and upset. I need to look after the family and at the same time, I look out of the window and wonder if DS1 is keeping warm and dry. I long to have him back in the fold but I guess that that will take a very long time - his siblings don't trust him at all and it'll take a long time to regain their trust (if ever he does) and to work through his mental health issues to the point where he is better or on the way and where I can be sure that the family is safe with him.
What should I do about the police - it's a terrible thing to have to ask them for help re one of your own but I have to and they are frankly uninterested.
Thanks -
