A teenage couple have been jailed over a ‘narcissistic’ plot to murder a girl who came between them.

Rhett Carty-Shaw repeatedly stabbed his ex-girlfriend Iman Nassir by his current partner Sarah Mohamed.

Mohamed, who has since changed her name to Kyro Mori Akihiro, encouraged him to kill Iman, then 16, after finding out he had secretly continued to see her.

She was ‘incensed’ and ‘humiliated’ and initially broke off the relationship.

Carty-Shaw arranged to meet up in an apparent attempt to win back her trust on May 3 and was told he would ‘have to work hard to win back her affections’.

The next day he turned up at Iman’s home in Openshaw, Greater Manchester, with a change of clothes and a large kitchen knife stashed in his bag.



The pair had sex and he then repeatedly stabbed her, leaving Imam with grave injuries she was lucky to have survived.

Carty-Shaw and Mohammed, now both 17, were jailed for 16 years each at Manchester Crown Court.

They can be named for the first time today today after a judge lifted reporting restrictions.

It emerged Carty-Shaw had googled ‘how long do people get sentenced for murder’ after meeting Mohamed.

Mohamed was seen loitering near the victim’s address and was found to have sent over 50 texts egging him on.

Iman told to the court how Carty-Shaw told her that he had to kill her, and at one point asked whether she would kill herself for him.

He told her people would harm his family if he didn’t, and asked her to look like she had been strangled so he could take a photo as fake evidence of her death.

She applied make-up to her neck to fake strangulation and closed her eyes for the photo, but opened them to find him standing over her with a knife.

A struggle ensued and she made it into the garden, where he landed blows with the knife to her head, neck and back before running back to Mohamed’s home.

He was arrested shortly after and was found in freshly changed clothes and an open packet of Dettol wipes, a large kitchen knife and bloodstained clothing and trainers.



Police found messages to Carty-Shaw on Mohamed’s phone asking him to ‘vid it then delete it when I see it please’ and ‘did you get rid of the phone?’

She also promised to find him a new identity, promising: ‘I would have done the same for you’.

Sentencing, Judge Alan Conrad QC said: ‘How the two of you could be intent on the murder of this girl really does defy belief, and can only sensibly be understood by reference to your two warped personalities.

‘You are both selfish narcissists who believe that the world revolves around you, and who play out your sick dramas on the stage of social media.’

Defending Mohamed, Peter Wright QC said: ‘It is a matter of considerable dismay and sorrow that a young woman with such obvious quality and ability with a potentially bright future before her, from her academic and extra curricular activities relating to her school, now faces the prospect of custody.’

‘Now she has dashed all hopes of a glittering career or future and she must now seek to make amends by way of rehabilitation.’

Katherine Pierpoint said Carty-Shaw has a ‘low level of intellectual functioning’, and that he is ‘susceptible to manipulation and coercion.’

He has ‘genuine remorse’ for what happened and has been a ‘model prisoner’, the court heard.

Carty-Shaw was found guilty of attempted murder and possessing an offensive weapon. Mohamed was found guilty of intentionally encouraging him or assisting him to commit murder.
