Ten killings involving patients of a mental health trust will be reviewed after the conviction of a man who stabbed a motorist to death.

Matthew Daley, 35, stabbed Donald Lock 39 times on the A24 in Findon, after the 79-year-old ran into the back of his vehicle.

He was convicted of manslaughter on the grounds of diminished responsibility.

The court heard his family had pleaded with the NHS to section him prior to the murder.

Sussex Partnership NHS Foundation Trust has apologised for its role and said it had commissioned a "thematic review" of 10 killings between 2011 and 2016 involving patients - including Daley - it had come into contact with.

The trust's chief executive Colm Donaghy said: "We decided there was a need to look to see whether lessons or common themes from the homicide emerged.

"The review of 10 cases is not to reopen those cases - it's to look at the themes."

During the trial, jurors were told Daley's mother pleaded with mental health experts to have her son sectioned.

She told the court the day she heard Mr Lock was killed was "the day that all your nightmares came true".

  • David Sole was jailed for life for the "motiveless and brutal" murder of a Jonathan Ellison in his Brighton flat in 2011

Mr Donaghy admitted the trust should have listened to those family pleas for help and said it had failed Daley.

"We should have carried out a formal assessment of a formal diagnosis for Matthew," he said.

"We had a diagnosis of Asperger's and what we should have done is had a formal diagnosis because he was also suffering from symptoms of psychosis.

"We should have also considered different ways potentially of treating Matthew. And finally we should have listened to the family more closely and taken action on some of the things they indicated."

"We failed in the care that we gave Matthew."

The mother of a former trust patient, who stabbed a woman to death seven years years ago, said the organisation should be "investigated and monitored long term".

The mental health trust apologised after an investigation found there were signs about the risks posed by Samuel Reid-Wentworth before he killed his victim in Littlehampton.

Angela Reid-Wentworth told BBC Sussex in an email: "When an organisation persistently and repeatedly fails then it comes from the top.

"There needs to be urgent legislation which makes health authorities and their professionals do their work properly and to be much more accountable."
