This wasn't a mugging gone wrong, or a case of being in the wrong place at the wrong time. In fact, the mother-of-one was the victim of Britain's first white honour killing. Her death was premeditated murder, plotted and committed by the boyfriend she was madly in love with. Laura's crime was to bring dishonour on her muslim lover Ashtiaq Ashgar, 21, who is now serving a life sentence for the brutal murder. By the time she was 15, Laura Wilson, from Rotherham, was besotted with Ashtiaq Ashgar, 16 In 2008, the couple began an intense relationship at school when Laura was just 15, and Ashtiaq, 16. Her sister, Sarah, reveals on tonight's episode of Britain's Darkest Taboos on Crime & Investigation Network: 'She loved him. She worshipped the ground he walked on, she really did. She would have done anything for him. Ashtiaq came from a traditional Muslim family who were planning an arranged marriage for their son with a girl from Pakistan. They would have been horrified to learn he was dating a white girl so he made Laura keep their relationship a secret. Unbeknown to his family, he lived a double life where he drank, smoked cannabis, carried weapons and had numerous relationship with women, including Laura. When Laura found out that he has been seeing other girls, they broke up and she slept with this married friend, 22-year-old Ishaq 'Zac' Hussein, to make him jealous. Only 16, she fell pregnant as a result of the fling and had a daughter, Alicia. Zac refused to acknowledge he was the father. After Alicia is born, Laura and Ashtiaq rekindle their relationship but he insists it must continue to be a secret. But while Laura was very much in love, her mother, Maggie, believes Ashtiaq was just using Laura for sex and treated her badly. She said: 'I heard a phone conversation between Laura and Ashtiaq, Laura telling him how much he loved him and he were just so nasty. You could hear Laura crying in the background. He was saying just how much he hated her and that he'd got another girl, and he wasn't interested in her and she's shouting back "I love ya, I love ya...." He used Laura I think at end. Ashgar comes from a very traditional Muslim family and was leading a secret life which Laura was a part of The two broke up and Laura began a short relationship with a married friend of his Laura soon became sick of being Ashtiaq secret's and on October 6 2010, fuelled by alcohol, she and her sister made the fatal mistake of revealing all to his family. They knocked on his mother's door and told her what was going on. Sarah recalls: 'Laura told her that she wanted to marry him, but his mother got aggressive and hit her with a shoe, calling her "a dirty white b****."' The whole time Ashtiaq stood behind his mother 'acting sheepish'. When sentenced, Ashgar 'showed no remorse, just upset at the amount of time he got in jail' The public episode would have been deeply shameful and embarrassing to him. On a roll, Laura and Sarah also visited Zac's family to reveal how he is the father of her baby. Maggie recalls: 'She said "I am sick of her being a secret" as she had been told not to mention about Alicia to any of family. So she told them but they just didn't want to know.' Maggie added that Laura's relations with Ashtiaq and Zac had 'fetched shame on their family... she had to be stopped.' In the days following Sarah and Laura turning up at their houses, an angry Ashtiaq sent Zac a text message saying: 'I'm gonna send that b***** to hell.' He also said he wanted to make 'beans on toast' of her, which actually means 'spill blood'. He asked Laura to meet him at the canal one evening and it's there that he brutally murdered her. VIDEO: The story of Laura Wilson will be broadcast tonight When Laura never returned home that evening, Maggie said she 'just knew' something terrible had happened. Meanwhile, Ashtiaq was trying to cover his tracks by texting Laura's friend asking if she had 'seen' her. Two days later, Laura's body was found in the canal. She had more than 40 stab wounds, most of those to the head, and some defence wounds. Maggie had to go identify her daughter. 'I went over and kissed her and I put my arms around her and I just sobbed,' she said. The day after Laura went missing, mother Maggie (left) 'knew' something terrible had happened Sarah was overwhelmed with guilt. She said: 'If it were going to be anyone it should have been me. It were my choice to go and knock on Ashtiaq's door, it were my choice to go and knock on Zac's door. She had everything to live for. Police charged Ashtiaq and Zac with murder - describing the case as Britain's first white honour based killing. Both men plead not guilty. On May 2011 at Ashtiaq's trial, the court heard how after stabbing Laura, he threw her into the canal but she kept fighting for her life. A pathologist report found that the stab wounds to the head were actually done to keep her under the water. On June 1 Ashtiaq changes his plea to guilty in the hope of a reduced sentence, as the evidence was against him. On December 21 the judge sentences 18-year-old Ashtiaq to 17-and-a-half years imprisonment for Laura's murder. 'He showed no remorse, just upset at the amount of time he got in jail,' says Maggie. Meanwhile, following a retrial Zac is acquitted of murder. Ashtiaq is currently serving a life sentence and will be eligible for parole in 2029 when he's 34-years-old. Sarah believes his punishment is not enough. 'He's going to be out in 2029... he can still get out and get married and have kids and have a good life. My sister can't,' she said. Maggie and Sarah are now raising Laura's daughter, Alicia, and this keeps them going. Maggie said: 'I need to keep strong for Alicia. I have got to make sure she has a good upbringing, good schooling. Keep her safe. Britain's Darkest Taboos is on tonight at 9pm on Crime & Investigation Network
