"I'm a compulsive liar pretty much... But this is definitely the truth."
'Vinny what have you done?': Teen says doctor admitted killing Amber-Rose
The teenager told police he feared for his own life after Skantha admitted he had murdered a teenager and stolen her cellphone.
The teen today told the murder trial the accused returned from the teen victim's house holding her blood-covered cellphone.
The teen witness told police in a video interview played to the court today that the accused later told him he had killed the victim, slitting her vocal cords to stop her screaming.
The trial for Skantha, 32, entered its second week today.
The victim was fatally stabbed in the bed of her Corstorphine home around midnight on February 2 after the defendant was driven to the address by a teenage boy.
The boy, who has name suppression, said he drove the doctor to Amber-Rose's house the night she was killed.
The teen's police interview is being played to the court today.
He said Amber-Rose and Skantha had an argument via Facebook messenger the night she was killed.
"I sent him a photo of an Instagram post Amber had put up. Venod got a bit ticked off. He said 'I'm coming to get you'."
The boy says Skantha told him to park around the corner, where he waited and listened to music.
"He was away for five to 10 minutes. Then he comes back and says "open the door. Don't let me touch it'."
The teen said Skantha was holding Amber-Rose's phone.
"It was in a clear case with her licence in it. I saw it was covered in blood. Then I saw him put one of his kitchen knives in the [car's] side pocket.
"I used to cook for him quite a lot – I knew those knives," the teen said.
'Vinny, What have you done?'
"I asked him; Vinny, What have you done?" He said it doesn't matter."
"Vinny told me he cut her ear so it was dangling off. She was just about to scream - and he says he cut her vocal cords. There was a dog in there but it was bloody useless.
"Then he just walked off – left the key in the door."
When the detective left the room in his initial police interview - the teen turned to the camera.
"Whoever does see this recording – I'm deeply sorry for what's happened, I wish I could've done something."
The teen said he himself felt unsafe after Skantha allegedly admitted the murder to him.
"I just had to act like the old me. It was just the whole, 'I don't care,' 'you're ruthless'."
