Husband heard son killing his mother on horrific phone call
He was in the grip of an 'acute psychosis' due to a schizoaffective disorder.
The father of a man who killed his mother during a mental health crisis heard the attack while on the phone with him, a court heard.
Gavin Nash, 40, stabbed his mother Lynette, 64, multiple times with a kitchen knife at the home they shared in Portishead, north Somerset, in June last year.
Bristol Crown Court heard that he was in the grip of an ‘acute psychosis’ due to a schizoaffective disorder.
Nash was charged with murder but the prosecution accepted his plea of manslaughter by reason of diminished responsibility.
Prosecutor Richard Posner said Nash’s family had been concerned about his deteriorating mental health and sought help from medical professionals.
On the day Mrs Nash died, two members of a community mental health team visited Nash to carry out an informal assessment.
He said: ‘The health workers advised the Nash family that if Gavin’s health did deteriorate further, it was an emergency, they should call the police.’
The court heard the fatal attack happened later that afternoon after Nash fled the family home.
After he returned, Mrs Nash rang her son’s father Stuart to tell him the defendant was back and as they spoke, he attacked her.
‘Stuart Nash had to listen to Gavin killing his mother,’ Mr Posner said.
A neighbour overheard an argument and then screaming, with the ‘chilling’ audio captured on CCTV.
Mr Posner added: ‘The defendant told his mother no one was coming to save her and to stay there. Lynette Nash told her son that he was scaring her and to leave her alone.
‘From the sounds being made, Lynette Nash was being stabbed to death by her son as he shouted to her, “Die you bitch, f****** die”.’
Nash phoned 999 and said: ‘I’ve murdered my mother. Police.’
In a victim impact statement, his father said there had been ‘missed opportunities’ to treat his son’s illness.
He added: ‘It’s very difficult not to blame the police officers or the crisis team for the lack of response, and whilst I try not to blame anyone in particular, I can’t help but going over and over, again and again, the missed opportunities that we all missed to save Lynette and Gavin from the horrific outcome.’
Nash, of Tansy Lane, Portishead, admitted manslaughter by reason of diminished responsibility.
David Maunder, defending, said the case was a ‘dreadful tragedy’ for everyone involved.
Mr Maunder read a note Nash had written to the judge in which he apologised for his actions.
Nash said: ‘Words cannot express how I feel. All I can say is that I’m desperately sorry and I loved my Mum. I often think that things could have been different if only I’d remained on my medication. But this is the reality that we as a family are faced with – one without Mum. We are devastated.
‘It is very hard to think that you will not be around any more and that that is because of me, even if I was very unwell at the time. Again, I’m sorry and I hope my story can help prevent anything like this happening again.’
Judge Martin Picton imposed orders under sections 37 and 41 of the Mental Health Act which meant Nash would be detained indefinitely in a psychiatric unit and would only be released when safe to do so.
The judge said: ‘Your mother loved you, cared for you and wanted to protect and nurture you.
‘Whether and what different decisions should have been made by health professionals and the police who had contact with you in the days leading up to this event will no doubt be a matter of anxious consideration.
‘At the very least it is to be hoped lessons will have been learned and nothing can now put right the irreparable damage that has ensued.’
