Mental Health Patient Jailed After Fatal Attack in Hillingdon
A mental health patient has been handed a hospital order after killing a fellow resident in a brutal attack at a Hillingdon care facility.
Deadly Assault at Pield Heath Road
The horrific incident unfolded at around 5.10pm on Sunday, 1 March, at the mental health unit on Pield Heath Road, Hillingdon. Ronnell Dennis, 26, launched a savage attack on 27-year-old David Siirak before fleeing the scene. David suffered severe head injuries and died in hospital three days later on 4 March.
Police swiftly launched an appeal to track down Dennis, who was arrested the next day, Monday 2 March, on suspicion of attempted murder. He was charged on Tuesday and appeared at magistrates on 4 March, where he was remanded in custody.
Charge Upgraded, Guilty Plea in Manslaughter Case
At Kingston Crown Court on 30 June, Dennis faced upgraded charges from attempted murder to murder. However, on 26 August, he pleaded guilty to manslaughter on the grounds of diminished responsibility—an admission accepted by the court.
On 28 September, Dennis was sentenced to a hospital order under section 37, with a restrictive order under section 41, meaning he will receive psychiatric treatment under strict supervision.
Family and Police React to Tragic Loss
Detective Sergeant Colin McKeen, from the Met’s Specialist Crime South, said: “David’s family have been left heartbroken by this. I know that this has been a truly painful time for them and, while today’s outcome will never bring David back, I hope that they find a little comfort in the sentence.”
David’s family released a statement: “We have suffered a great and terrible loss after David’s tragic death on 4 March 2020. This has been a life-changing experience. Life will never ever be the same for us without David. David was a strong and much-loved young man, and he will eternally be missed by us all.”
