Veggiefan, thanks.
VT's plea of manslaughter was denied and rejected by the Crown. It was not accepted, so they're prosecuting him, not on m/s but on Murder. Therefore that plea is not "in", so to speak. He faces varying charges ... all of murder. He may have said it was someone else; he may have said "I'm not guilty" ... the Crown are pursuing Murder Charges against him - they have disregarded his plea totally.
I think the evidence is immense in this case - and I think he's in for a lot longer than may be anticipated - but then that's JMHO.
Totally agree, the CPS will have carefully studied all the evidence gathered by the police. They have the final say as to whether the charge of murder is appropriate in this case. They have decided that the evidence against him warrants a trial for murder and must be confident that he will be convicted of such by a jury.
