A teenage killer was 'off his head' on drugs when he acquired the knife he used to stab his victim, a murder trial jury has heard.
Scott Anderton's body was recovered from the Leeds and Liverpool Canal, in Leigh, on the morning of March 25.
Three teenagers are on trial at Manchester Crown Court accused of murdering the 33-year-old, who prosecutors say suffered 35 stab wounds.
Two of the boys, aged 16 and 17, deny the charge.
Liam Bailey, 18, has pleaded guilty to murder.

Prosecutors say the trio lured Mr Anderton to a secluded spot on the canal near King Street - before stabbing him to death, pushing him into the water and taking his belongings.
Jurors have previously heard that the defendants encountered Mr Anderton 'purely by chance' when they found him wandering the streets alone at night.
Today (Thursday), Bailey told the jury he had acquired the knife used to stab Mr Anderton after meeting 'a friend' several hours earlier.
He claimed he could not remember exactly when he got the weapon, or who gave it to him.
Bailey told the court it was 'a joint idea' between him and the 16-year-old - Boy B - to get the knife, which he believed they collected on a street.
"I don't think we bought it," he said.
"We just took it.
"I know we were meeting a friend for a knife, but I can't remember who it was."
Jurors were shown evidence of a number of phone calls made between Bailey, Boy B and another man, Logan Atherton, throughout March 24 and into the early hours of March 25.
Boy A's defence barrister, Nigel Power QC, asked Bailey about a phone call Boy B is alleged to have made to Mr Atherton shortly after 7pm, which lasted for one minute and 39 seconds.
"I didn't make the call so I didn't know what was being said," Bailey told the jury.
"This would have been six months ago when I was on drugs, so I can't really remember a one minute conversation."
Mr Power alleged three phone calls were then made from Bailey's phone to Mr Atherton between 12.07am and 12.15am on March 25, all of which were unsuccessful.
When asked why he made the calls, Mr Bailey told the court: "I was probably off my head and seeing if he wanted to meet us."
Jurors heard that eight minutes later, Mr Bailey's phone was located in or around Thirlmere Street, where Mr Atherton lived.
Mr Power said analysis of Mr Bailey's phone showed it remained in the area for a further 16 minutes.
Mr Bailey told the court he 'could not really remember the situation' due to the effects of the drugs he had taken several hours earlier.
He added that he was able to remember murdering Mr Anderton later that morning as the drugs had 'started to wear off' by then.
Both Boy A and Boy B, who cannot be named for legal reasons, deny murdering Mr Anderton.
As well as Mr Anderton's murder, Bailey, of Diamond Street, Leigh, has also pleaded guilty to charges of assault occasioning actual bodily harm and grievous bodily harm in relation to a separate incident on September 1, 2020, on another man.
Boy A is also accused of grievous bodily harm on the same man and one offence of attempted robbery, both of which he denies.
Bailey and Boy B are accused of two offences of attempted robbery, which they both deny.
