The prosecution alleged that Mr Morris carried out the killings after his sexual advances were rejected by Mrs. Power.

Morris flew into a rage and embarked on what the jury heard described as an "orgy of savagery". Patrick Harrington QC, prosecuting, said Mrs Power alone had been beaten 38 times with the murder weapon. Doris Dawson was murdered as she lay in bed. Morris then set her body alight. One of the children's bodies lay on the landing. Another was found in their bedroom, still in a cowering position.
David Morris was caught after a bloodstained gold necklace, ripped from his neck during the murders, was found in the victims house by forensic scientists.
Paint found on the jewellery exactly matched paint found on kitchen units at Morris' home.
In police interviews, he insisted the chain did not belong to him - only to later change his story and admit it did. The jury had been told that Mrs Power had spoken about how much Morris frightened her, and had previously been beaten by him.
The trial judge, Mr Justice Butterfield, ruled the jury could be told about Morris's almost two dozen previous convictions for robbery and violence.
Three other people originally arrested over the murders are to sue the force for damages.
About a year after the murders, Mandy Power's lesbian lover Alison Lewis was arrested on suspicion of the murders. She was held along with her then husband, police sergeant Stephen Lewis, and his brother Inspector Stuart Lewis. All three were later released without charge.
