Jasmine tells Pearl what is happening and gives her a car that David bought for her. Jasmine and David reconcile briefly but split again when he has an affair with Nicola De Souza. Jasmine gets revenge on Nicola by exposing her lies about her husband, Donald De Souza, in the local paper and making sure his son, Miles, reconciles with his father and stops drinking again.

Jake and Jasmine start dating, despite tension between their families over the baby swap of Daniel and Arthur.
Jasmine decides to write a story about a local criminal family; the McFarlanes. Using Debbie's contacts, she meets policeman Shane Doyle at The Woolpack. Shane later goes to Jake's house, claiming there have been complaints about the noise, and winds Jake up so much that Jake attacks him. Shane promptly arrests him for being drunk and disorderly while Jasmine dumps him for thinking that she'd cheat on him. Shane makes his personal interest clear but Jasmine is not interested until she learns Shane has arrested Danielle Hutch, a girl with ties to the McFarlanes. Debbie warns Jasmine to stay away from Shane, but she refuses to listen. Shane tells Jasmine that he let Danielle go because he felt sorry for her and they sleep together.
When Jasmine questions Shane further, he almost becomes violent so she searches his flat and finds large amounts of cash. Unfortunately, he finds her hiding in a wardrobe and boasts about his illegal activities. Jasmine pretends to understand his reasons before trying to escape but Shane catches her and tries to rape her. Debbie arrives and hits Shane on the head with a chair leg, knocking him out briefly, but he comes round and grabs Debbie. Jasmine picks up the chair leg and hits Shane over the head four times, killing him. Debbie, Eli Dingle and Jasmine wrap Shane's body up and dump it in a lake at Home Farm.
Jasmine buys a plane ticket online using Shane's credit card, as he had some time off work but starts having nightmares. Shane's body is found by Victoria Sugden after she falls into the lake. Debbie and Eli try to keep Jasmine calm before the police question her. Laurel, however, notices how jumpy Jasmine has become and asks if she is pregnant, making her laugh hysterically before admitting to Laurel that she killed Shane so Laurel tells her that she must go the police. Jasmine agrees but on hearing of Ross Kirk's arrest and that he has been charged with Shane's murder, Debbie and Eli persuade her to keep quiet but Jasmine's conscience gets the better of her and she tells Debbie that she wants to go to the police and confess.
Calling her bluff, Debbie packs a bag and drives Jasmine to the police station. While there, the girls have a heart to heart and they kiss again and start dating again. However, Ross is cleared and Eli is arrested for Shane's murder, so Debbie and Jasmine decide to go on the run. Debbie takes a taxi and Jasmine catches a bus to meet her but Debbie is arrested so Jasmine leaves alone. She visits her grandfather in Scotland but returns and bursts into a court hearing for Debbie and admits killing Shane.
After being questioned by the police, she is charged with manslaughter. Jasmine pleads guilty and is sentenced to four years in prison. Debbie visits and Jasmine tells her she does not want to see her any more because she needs to fit in. The two girls say goodbye and Jasmine explains that their love will last forever. She is then led back to her cell.
- Jasmine would have been released in 2013, but it was not mentioned by anybody. She also did not attend Ashleys' funeral, so it is possible she had not heard about his death (or got back in touch at all since leaving prison)
