'Sniggering' killer Imran Hussain, 27, guilty of murdering teenage gap-year student Kieran Crump-Raiswell Kieran Crump-Raiswell, 18, stabbed to death as he waited for a bus Imran Hussain attacked him 'without warning' in Chorlton, Manchester The gap-year student had CVs in his bad and was out job-hunting Hussain, a mature student from Coventry, denied charge of murder Admitted manslaughter on grounds of diminished responsibility But jury rejected claims he was suffers from paranoid schizophrenia Killer: Imran Hussain, 27, has been found guilty of stabbing an 18-year-old gap year student to death in Manchester A 'sniggering' killer has been found guilty of murdering of a teenage gap-year student who he randomly stabbed in the street for no apparent reason. Kieran Crump-Raiswell, 18, was on his way to look for a job when Imran Hussain, 27, walked up and stabbed him four times in the chest 'without warning'. Witnesses to the shocking scene in Whalley Range, Manchester, said Hussain was 'sniggering' and 'laughing' as he ran to his car and drove off. Hussain, of Tilehurst Lane, Bracknell, had denied murder but admitted manslaughter by reason of diminished responsibility following evidence that it was 'highly likely' he is suffering from paranoid schizophrenia. But a jury at Manchester Crown Court rejected his defence and agreed with prosecutors that at the time he 'simply wanted to see what it's like to kill someone'. The killing was the second of two street assaults committed by the defendant on total strangers within 12 days in January. Mature student Hussain, from Bracknell, Berkshire, drove from his student flat in Coventry on January 4 and punched a man in the face in Nottingham and ran off. His victim made a note of his vehicle registration number and spoke to police soon after but he remained undetected when on January 16 he travelled to Manchester. In his opening speech, Peter Wright QC, prosecuting, said: 'It is the prosecution case that on this occasion, fortified by the apparent ease at which a stranger could be attacked, this time he travelled to Manchester armed with a knife and intending to kill someone.' Hussain drove around Whalley Range and Chorlton in the early afternoon for around a hour as he looked for a 'suitable victim', the lawyer said. Random: Gap year student Kieran Crump-Raiswell was walking to a bus stop in Chorlton when he was attacked He parked up and then attacked the teenager as he walked near to a bus stop in Upper Chorlton Road, he added. Mr Wright said the defendant initially denied involvement in either of the incidents when he was arrested days later, but he 'changed his tune' when the evidence against him began to unravel. He said Hussain went on to claim he had been hearing 'threatening and abusive voices' and that he travelled to the two cities to confront them. Mr Wright suggested that Hussain's medical defence was 'contrived by him as a last resort that only arose once he realised it could be proved he was the culprit'. At the time of his death, Mr Crump-Raiswell lived with his parents Roland and Christine and his younger siblings in the Chorlton area. Victim: This CCTV footage showed Kieran Crump Raiswell taken moments before he was stabbed to death in January Heartbreaking: The 'caring and quiet' teenager was out looking for a job when he was stabbed to death in the street He had obtained a place at Sheffield Hallam University to read history and was due to commence his degree course in September this year. The defendant was studying engineering at the University of Coventry and lived in rented accommodation in Barras Lane, Coventry. Mr Wright told the jury that several relevant Google searches in January were later discovered on Hussain's laptop, and he had looked up driving directions from Birmingham to Manchester and Stretford. Random: The attack was Hussain's second street assault on total strangers in 12 days Callous: Hussain was heard to be 'sniggering' and 'laughing' as he ran from the scene Google map searches were also keyed in for Reading, Dunstable, Lincoln and Nottingham, with the internet history later deleted, he added. The defendant had initially studied business at the University of Westminster but was excluded after failing course modules, the court heard. He was in the second year of an undergraduate course in electrical systems engineering at the University of Coventry at the beginning of this year. Investigations had failed to identify anyone who socialised with him there, Mr Wright said. He was described as being 'quiet' and 'isolated' by students. Sentencing will take place at 2.15pm tomorrow. In mitigation, Alistair Webster QC, defending, said it had been the Crown's case that Hussain was either not suffering from a mental illness or, if he was, it did not sufficiently explain his conduct. The Crown did not call any evidence to dispute the view of several psychiatrists that the defendant, who is being treated at maximum-security Broadmoor Hospital, is currently mentally ill. He submitted that a 'perfectly rational explanation' for the jury's verdict was that, although Hussain was guilty of murder, they did accept that he suffered from an underlying psychotic condition. Rick Holland, on behalf of the Crown, said there had been a 'significant degree of planning and pre-meditation' and thereafter the defendant took steps to conceal his guilt by hiding the knife used and a T-shirt he wore at the time of the killing. A probe by the Independent Police Complaints Commission (IPCC) into Nottinghamshire Police's response to the assault in Nottingham - 12 days before the murder of Mr Crump Raiswell - was launched earlier this year and is ongoing. Heartbreak: Kieran was about to get the bus in to Manchester city centre to look for a job - he was carrying his CV and passport in a backpack Investigation: The police complaints watchdog is looking into Nottingham Police's response to Hussain's earlier assault - 12 days before he killed Kieran, pictured with his mother Christine Charlotte Rimmer, District Crown Prosecutor at CPS North West, said: 'As a result of the verdict reached today, Imran Hussain has been found guilty of the senseless and brutal murder of Kieran Crump Raiswell. It was an unprovoked attack on a young man who had his whole life ahead of him. Throughout the investigation and the court case, Imran Hussain has refused to accept full responsibility for his actions, instead choosing to hide behind the defence of manslaughter by reason of diminished responsibility. Nevertheless, the CPS has been determined to bring him to justice and we have worked hard to piece together the evidence and build a strong case against him for the more serious charge of murder. 'Consequently, the jury have rejected his version of events and accepted the prosecution's case that Imran Hussain was in fact fully in control of his actions when he travelled to Manchester and stabbed Kieran to death in full view of passing members of the public. 'At the heart of this truly saddening case in the tragic loss of an innocent man's life and I would like to offer my sincere condolences to Kieran's family and friends. 'Although today's outcome will not bring Kieran back, I hope that it goes some way towards helping them come to terms with their loss.' The family of Kieran Crump-Raiswell have said his murder was 'completely senseless'. The 18-year-old was stabbed to death in the street in Whalley Range, Manchester, by total stranger Imran Hussain, 27, in January. The youngster was on a gap year ahead of his acceptance to study history at Sheffield Hallam University later this year. The Manchester City fan had just returned from the United States where he was on a three-month football coaching course in Virginia. He lived in Chorlton with father Roland Crump, 54, mother Christine Raiswell, 45, his sister Anna, 17, and brother Paddy, 14. He was heading into Manchester city centre to find a job when he was attacked without warning in broad daylight in front of stunned witnesses. His father said: 'Kieran had been into Manchester the previous day with his CVs in his bag and had been handing them out. He headed out into town again. He left the house and I was the last one to see him. He just said that he was going into town. Kieran was quiet. He never had a bad word for anyone. No one ever had a bad word for him. Five hundred people turned up to the funeral. The response from the wider community was just fantastic and we want to say thank you. 'Mature': Kieran's mother said he was 'caring' and was just 'turning into a man' when he knifed to death at the age of 18 Mr Crump, who works as an interpreter and translator, added: 'He had his whole life in front of him and was planning for the future. He was quite a mature person for his age. He was very family-orientated. He spent a lot of time with his family and he enjoyed his family. He would really look after Paddy and Anna. It is such a big loss for our other two children that they have not got him here. He was a caring big brother. Mrs Raiswell, a public health programme manager for Manchester City Council, said: 'It is so completely senseless. People have said things like he was in the wrong place at the wrong time, but he wasn't. He was just walking along enjoying himself and somebody has attacked him. He did not have a chance to do anything. There was no motive. It was just a random, violent assault. It has been very difficult as a family. We have got two other fantastic children and we do not want the impact on their lives to be worse than it has been. It is very, very hard because we feel his loss all the time, and that will continue. I think of him everyday and I am going to miss him everyday. People ask all the time and say they cannot imagine how we feel. It feels a bit like you have lost a leg. You will never be the same again and it will always be very apparent, but you learn to adapt. She continued: 'He was never in any trouble. He did well at his exams and he was very reliable. He played for the same football team for 10 years and was incredibly loyal to his friends and his family. He was 18 and he was turning into a man. He had a real social conscience and did not like to see injustice. He would give his change to homeless people and he had done some voluntary work for FareShare, a food supply organisation for the vulnerable, homeless and needy. It was just before Christmas and he was helping fill the hampers with food and goods for the needy. He felt very strongly about those sorts of issues. He was quiet, but he had those great strengths. Mr Crump also told how he has now moved seats at the Etihad Stadium as he watched Manchester City with sons Paddy and Kieran, who played for Sale Cricket Club and football for FC Bluestar in Didsbury. Mr Crump said: 'At football it is just me and Paddy now who watch City. We did have three seats in the family stand. Thanks to City we have been moved to another part of the ground because it is not the same. This is something that is not going to go away.
