A Sheffield killer stabbed and slashed a teenager with a razor and a pair scissors months before she murdered Walkley man Craig Wild.
Sheffield Crown Court heard Alison Moss, 46, of Fox Walk, Walkley, attacked a 17-year-old male inside her flat in an unprovoked assault after inviting him back with a 16-year-old female friend on January 11, 2016.
The court heard Moss was taking drugs and her mood changed after the 17-year-old returned from the toilet. She began shouting allegations the victim was a 'nonce' and a 'peadophile'.
Moss shouted 'you need to cut for the devil, I am the devil' and 'you move, you die' and started spitting at the victim before she launched into the frenzied attack.

Andrew Robertson QC, prosecuting said: "She picked up the razor and started to slash at him and he put his arms up to protect himself."
Mr Robertson said the victim pleaded 'kill me now' but Moss, who was laughing as she carried out the frenzied attack, replied 'no, that's too easy'.
Twisted Moss locked the patio door and then made the 16-year-old girl clean the razor she attacked the victim with and threatened her.
The girl managed to contact a friend who rang the police but when she returned from the kitchen, Moss had stabbed the victim in the head with a pair of scissors and pulled on his tongue which made him wretch.
Police arrived and Moss said: "I only wanted to give him a clip."
She initially denied slashing the 17-year-old and said he had done that himself.
The court was told the victim had a 7.5cm cut to his head and 4cm cuts to his forearms.
Sentencing Moss, the judge, Mr Justice David Holgate said: "You have shown absolutely no remorse for what you have done."
In a statement read out by Mr Robertson QC, the 17-year-old said he still carries the scars of the attack.
"This has made me petrified, frightened and scared. I've been put off from going out with my anxiety and I don't want to go out again.
"I feel sorry for Alison - I want her to get some help. I don't know how I will get over this."
The court heard Moss was on bail when she and co-defendant David Webster attacked 'popular' Walkley man Craig Wild inside her flat in August, 2016.
Moss, who was sentenced for 10 years for this offence admitted the attack at an earlier hearing and had no previous convictions before the incident.
Moss pleaded guilty at the first day of the murder trial for this offence.
