A mother, Sharon Lees, is demanding a public apology from Hywel Dda health board for the death of her son, David Fleet, who stabbed a man to death 10 days after being released from a psychiatric unit.

Sharon warned hospital staff that her son was still buying cannabis and looking for knives and believed that staff "could and should have been prevented" the tragedy.

The victim, Lewis Stone, was walking his dog when Fleet stabbed him, and the family of the victim says their lives have been permanently changed by the attack.

A mentally ill person, David Fleet, stabbed and killed a man named Lewis Stone during a walk with his dog in 2019.

He had not received his medication and had a history of violent outbursts.

Fleet was sent home without an update on his risk assessment and staff missed the day before the attack.

The article mentions that 11% of homicide offenders in the UK were under the care of mental health services in the years 2010-2020 and that the percentage of homicides carried out by people with schizophrenia increased.

The Welsh government has stopped conducting independent mental health homicide reviews, which means lessons from this and three other killings have not been shared.

The article also mentions that Lewis Stone's family is not satisfied with the way the investigation was handled and they want an apology from the health board.
