Double murderers Kenneth Burgess and Dennis Robinson will spend at least 15 years behind bars for killing the Cooper twins, a court ruled yesterday.

Rochelle Cooper, who was taken to hospital on Thursday after collapsing in court moments before the guilty verdicts were confirmed, danced out of court yesterday.

The twins' mother said she was ?happy, happy, happy? with the sentences ? although other family members and friends said the prison terms were too soft.

One said the death penalty should be reintroduced and imposed only after the pair had served their double life sentences, for a crime that saw Burgess pummel Jahmal and Jahmil to death with a metal baseball bat.

The woman, who asked not to be named, added: ?Even if they apologise they will never be forgiven. Nothing can bring those boys (the twins) home.?

Prosecutors had asked trial judge, Chief Justice Richard Ground, to use his discretion so Burgess could serve up to 25 years. But the judge said the law did not allow him to do this.
