Stephen Lawrence murder: Attorney General to review sentences Mr Justice Treacy, who presided over the seven-week trial, sentenced Dobson to at a minimum jail term of 15 years and two months and David Norris to at least 14 years and three months. But he had to sentence them as juveniles as both were under 18 at the time of the murder, in Eltham, South London, in 1993. The judge suggested he would have doubled the minimum sentence if the law had allowed. While the starting point was 12 years, the judge also took into consideration that the attack was racist, premeditated to some degree, involved a knife and was unprovoked. Doreen Lawrence, Mr Lawrence's mother, said she felt her son's killers should have been jailed for life. In a newspaper interview, she said: "I'm hoping that, eventually, Dobson and Norris will give up the others; that they won't take the whole guilty vote for themselves. They took my son's life, so I feel they should be given life with a minimum of 20 years. She also expressed hope that Norris or Dobson might now name the oher members of the racist gang responsible for the crime. "I want to get the others, but I also want a life," she said. Dominic Grieve, the Attorney General After passing his sentence, the judge urged the Metropolitan Police not to close the case and to keep hunting for the other suspects who remain at large. Police have said they do not have enough evidence to prosecute other suspects and concerns have been expressed that the investigation will be disbanded, not least because of cut backs within the force. Officers in the team do not work on other cases and are dependant on new leads. Five people got in touch with police during the trial offering information and police are now assessing whether they can build a case against the other suspects, Neil Acourt, Jamie Acourt and Luke Knight. The officer in charge of the case, Det Chief Insp Clive Driscoll, said: "We have had people who have phoned in during the trial and offered their assistance and we are looking at that to the best of our abilities. After sentencing Norris and Dobson at the Old Bailey on Wednesday, Mr justice Treacy called Mr Driscoll forward.
