A teenage witness has told a jury he believes the fight which led to a schoolboy being stabbed to death was over a TikTok live.

Evidence from juvenile witnesses is continuing to be heard this week at the trial of a 15-year-old accused of the murder of 14-year-old Christopher McBurnie, who was stabbed to death in Ramsey on May 29 last year.

The defendant, who cannot be named for legal reasons, admits inflicting the fatal wound but claims he was acting in self-defence. He has pleaded not guilty to murder.

Much of the evidence heard so far at the trial has come from teenagers who were at the scene of the stabbing.

On day five, evidence was heard from a boy who was 16 at the time, but now 17 years old, who heard about the fight and joined the group of boys heading to the defendant’s home in Ramsey.

The boy described how he stood outside the defendant’s home and shouted out in an attempt to ‘provoke’ the defendant. He said the confrontation between Christopher and the defendant ‘lasted only seconds’.

When asked by the police officer interviewing the witness what the fight was over, he said: ‘I’m not sure but I heard it was over a TikTok live which is pathetic. Stupid stuff.’

The witness did not go into any further detail about what TikTok live he was referring to. TikTok Live is similar to Facebook Live in which content providers can stream videos in real time. To use the option, you need at least 1,000 followers and there should be an age restriction.

In his recorded interview, the witness also described what he saw that day.

He said: ‘They walked up to each other and Chris moved to punch him and there was a tussle.

‘Suddenly, Chris shouted “ow, what the f***!”

The witness said he had seen the knife on the defendant’s hand and had made a stabbing motion at Christopher’s back as they grappled, although no stab wound was found in Christopher’s back.

He said Christopher staggered back and collapsed on a grass area. A woman attended to him and told the witness to run in and get some towels to help stem the bleeding.

The witness said he had known the defendant since childhood but had not spoken to him for a year or so.

He said: ‘I did not know he [the defendant] was capable of doing something so stupid. I don’t know what got into his head.’

In cross examination, defence advocate Siobhan Grey KC went through Snapchat messages the boy exchanged with the defendant on the day of the incident.

The witness agreed that the feeling was between them that not much would actually happen in regards to any fight.

The witness described Christopher as being ‘energetic’ as he walked to the defendant’s house for the confrontation.

Last week, a teenager told a jury he’d been asked to film what he thought would be a fist fight - but ended up recording the fatal stabbing.

The trial continues at Douglas Courthouse.
