Prosecutors have dropped a murder charge against one of the six teenagers on trial over the death of Mandurah sailmaker Tauri Litchfield.
Late this afternoon, State prosecutor Amanda Forrester applied to have a murder charge against one of the six teenagers discontinued.
The five teenagers - aged 14 to 16- still on trial are accused of chasing Mr Litchfield on Pinjarra Road in Mandurah on March 17 last year.
Prosecutors allege the 14-year-old had touched Mr Litchfield's back pocket and was possibly attempting to steal his wallet, prompting the 28-year-old to smack the teenager on the back of the head.
The 14-year-old is accused of retaliating by punching Mr Litchfield with enough force to knock him off his feet.
Mr Litchfield was allegedly chased by the five boys before he fell from a wall and struck his head on a bitumen car park.
