Dean Mayley murder: Witness appeal over man's death
- 30 May 2014
- From the section London
Images have been released of three men police want to speak to in connection with the murder of a vulnerable man who was stabbed in west London.
Dean Mayley, 24, was attacked in Ruislip Road, Greenford on 7 February. A post-mortem test found he died from a single wound to the chest.
Police say the three men in the CCTV images are not suspects, but are potential witnesses.
Three 17-year-old men and a 19-year-old have been charged with murder.
A trial has been set for 4 August at the Old Bailey.
Two of the men pictured were present at the KFC in Greenford Broadway prior to the stabbing while the third image shows a man who walked past Mr Mayley seconds before the attack.
Mr Mayley, of Northolt, west London, died in hospital. He was on his way to see his uncle when he was attacked.
The victim had a developmental disorder which left him with moderate learning difficulties and a mental age of nine.
It meant he rarely left home alone, except to visit relatives.
Lead investigator Det Ch Insp Matt Bonner said: "I am urging those in the images we have issued to please come forward and help us with our enquiries.
"Likewise there may be people who recognise these three men; don't remain silent, please come forward and help us."
