A gang of youths in Britain have been jailed for stabbing to death a man with the mental age of nine as they attempted to steal his phone.
Jamal Jones (17) was found guilty of murder and was sentenced to life with a minimum of 15 years, while three other teenagers also involved in the attempted robbery, were also jailed.
Jones was caught on CCTV stabbing Dean Mayley (24) in the heart after he approached him on a street in west London and demanded his mobile phone.
He denied he meant to seriously injure Mr Mayley when he wielded the knife against him.
"It was Jamal Jones who plunged the knife into Dean's heart," Judge Martyn Zeidman QC said.
"But make no mistake, you all have blood on your hands. You each played an important part in this event and you did so knowing that Jamal had a knife and realising that he might stab Dean with it."
"Put bluntly, now Dean is dead and it's your fault."
