Christian Lacey, 21, left police custody on April 26 last year, and two hours stabbed his mother, 63-year-old Liz Lacey
Medical staff showed a 'lack of professional curiosity' while examining a man in the grip of schizophrenia, missing two chances to stop him killing his mother, a report has found.
A review has suggested police, a GP and mental health workers showed 'unconscious bias' and 'made an assumption' that seriously ill Christian Lacey was not dangerous - because he was 'well dressed and from a nice family.'
Lacey, 21, was able to leave police custody on April 26 last year two hours before stabbing his mother, 63-year-old Liz Lacey, despite having already tried to strangle his father, Johann Wierzbick, and half-brother, Jacob Carfoot, the previous day.
After killing Ms Lacey at her home in Garston, Liverpool, he walked to his grandmother's nearby, where he tried to kill her carer Edwina Holden by stabbing her 12 times.
Ms Lacey's body was discovered by her brother Ian Wright, after being subjected to what the review termed 'a manic act of violence.'
It later emerged Lacey's worried family had taken him to A&E at the Royal Liverpool Hospital on March 30, where his paranoid schizophrenia was also missed.
On that occasion he had gone missing in London for hours, where he described giving his brand new mobile phone to a homeless man because he thought it had been hacked and he was going to die.

Lacey was initially charged with murder and attempted murder, but the Crown Prosecution Service (CPS) agreed to accept pleas to manslaughter on the grounds of diminished responsibility after details of his illness came to light.
Lacey is now a patient at high security Ashworth Hospital in Maghull, having being made the subject of an indefinite hospital order at Liverpool Crown Court.
Judge Clement Goldstone, QC, passing sentence, had ordered Merseycare NHS Foundation Trust to make public a report of an review into what went wrong with Lacey's care, which has now been shared.
The report states: 'The review identified that in the panel's opinion the root cause of the incident was [Lacey's] complex presentation which was not explored by the practitioners in depth.
'This lack of exploration may have been due to [Lacey's] presentation as well as a lack of sufficient training in exploring
