UK boy tried to stab his ex-girlfriend and his mother after having sex with her • Reason: Wanted to prove his love for his new spouse

UK: Rharty-Shaw, a 17-year-old British teenager, plotted to murder his ex-girlfriend and 16-year-old mother, Iman Nasir, after his current couple found out the two were still dating - and separated from him following the startling discovery. So that he can win his beloved's heart again, Karti-Shaw murders Nasir.

According to media reports in the UK, the murder was scheduled for last May 4, when Carte-Shaw arrived at Nasir's home in Manchester, with a large kitchen knife and a bag containing clothes to replace. He and his 17-year-old partner, Sarah Mohammed, spent two hours together at Nasir's home, and even had sex before the brutal attack planned by Karti-Shaw.

Meanwhile, Muhammad waited for Kurti-Shaw at the house and sent him numerous text messages as she pressured him to video-record his actions on the spot and send her the photos.

In her testimony about the incident, Nasir said that Karti-Shaw had explicitly told her that he had to murder her and asked her if she would like to kill her, and what methods he should use to kill her. According to Nasir, he claimed that she was pressured to murder her and that his family could be harmed if he did not. In addition, he asked her to look as if she had strangled her so that he could photograph her and send the photo as "testimony" to her death.

Nasir decided to cooperate with his request and made her neck look as if she were choking. However, when she opened her eyes, she was horrified to see Carti-Shaw holding a knife. At this point, Nasir tried to call for help, but he prevented her from making a phone call.

Nasir tried to fend off Carty-Shaw and shove him down the stairs of her house toward the garden, but he managed to take hold of her and stabbed her with the knife many times in her head, neck and back before fleeing the scene.

Shortly thereafter, he was seized by police forces as he possessed two bags containing used wipes, a large kitchen knife and bloodstained clothes. Police later also located Muhammad and found on her cellphone messages instructing Kurti-Shaw not to make a foolish move and leave the DNA imprints at the ex.

Nasir, who survived the assault, was hospitalized with serious injuries. She has reportedly since moved to a more remote residence with her son.

Last Friday, the Manchester court allowed the publication of Kurti-Shaw and Mohammed. The two were sentenced to 16 years in prison.
