RJR News / Defence attorney Carlton Collman has urged the seven member jury to find Michael McLean not guilty of the murder of six people, including four children, in St.Thomas 12 years ago. He was making closing arguments at the trial before the Home Circuit Court Wednesday morning. McLean is on trial for the February 26, 2006 killing of the children and their mothers. In his submissions, Mr. Collman argued that there is no evidence linking McLean to the murders. He said the case was poorly investigated by the police and the evidence put up by the prosecution should be rejected.
