A striking-looking man with long blond hair was repeatedly stabbed and had his throat cut after making a sexually suggestive remark, a jury has been told.
Memories differed about the actual comment, but prosecutor Sandi McDonald SC said one witness recalled the victim telling Michael Joseph Lindsay something like: "I will pay you for sex".
Another witness understood the comment to be jocular and to be directed at the whole group, she said.
Ms McDonald was opening the crown case at the South Australian Supreme Court trial of Lindsay, 29, and Luke James Hutchings, 30.
They have pleaded not guilty to murdering Andrew Negre, 37, whose dumped body was found in a reserve at Hallett Cove, in Adelaide, on April 8, 2011 about a week after he died.
Ms McDonald alleged that after Mr Negre's sexual comment, Lindsay punched him to the ground and Hutchings held his legs as Lindsay went through his pockets and took money.
Lindsay stabbed Mr Negre at least 25 times before Hutchings came from behind and slit his throat, the prosecutor said.
Mr Negre had been drinking with his partner on the night of March 31, but when she left him at the Cove Tavern to go home, he met Lindsay who was with two other people.
Ms McDonald said other patrons would give evidence about seeing the group with Mr Negre, who was "quite a distinctive man" being very tall and "very striking" with long, straight blond hair.
They allegedly went back to Lindsay's home, where Hutchings was a boarder, and they and a number of other people socialised and drank alcohol.
Mr Negre's partner tracked him down and after finding him to be drunk, she went home after Lindsay said he would drop him back there the next day.
Ms McDonald alleged that after Mr Negre was murdered, his body was transported to a nearby reserve in a wheelie bin.
The trial is continuing.
