Emma Siswick murder: Jonathan Sutton jailed for at least 28 years
A "paranoid and controlling" former policeman has been jailed for at least 28 years for murdering his pregnant partner, stabbing her 81 times.
Emma Siswick, 37, was found at a house in Huddersfield with wounds from a knife and broken glass on 18 May.
Ex-PC Jonathan Sutton, 40, admitted murder. He also pleaded guilty at Leeds Crown Court to wounding two boys with intent at the property.
The children were treated in hospital for non-life-threatening injuries.
The court heard Sutton had been a police officer with West Yorkshire Police between May 2003 and November 2004.
The judge, Mr Justice Edis, said Sutton's offences were "as serious as it's possible to imagine".
"Looking at the photographs of the house where all this happened is a truly horrific experience," he said.
"There are three different sites in that property where very serious assaults with knives were carried out.
"There's blood everywhere. You inflicted 81 separate cut injuries to Emma. She fought you to try to save herself."
The judge also said there had been "irreparable harm to those still alive after the incident".
He said it had left the children "with physical scars that they will see every day of their lives", adding: "One can only speculate about the mental scars which they will be left with."
Jailing Sutton for life, the judge described the former officer as a significant risk to the public and said he must serve a minimum of 28 years.
Bryan Cox QC, prosecuting, said the boys' injuries would have a "profound and lasting effect on their lives".
He said Sutton was a "jealous, paranoid and controlling man".
Det Ch Insp Adrian Taylor said police had been called to the property at 21:30 BST on 18 May to reports of a continuing domestic incident.
He said: "What we found there was much worse - a 37-year-old woman had been killed and two children had suffered serious stab wounds.
"We may never know the reasons why he carried out this brutal attack but we welcome this guilty plea for Emma and the two young children he seriously assaulted.
"We hope that her family can now start to rebuild their lives and move on from this horrific incident."
A spokesperson for Ms Siswick's family said: "We would like to thank all her family and friends for their unwavering support throughout this devastating time."
