“You might have been driven to do what you did because you could not face losing Angela Rylance.

“It was not the first time that you had seduced other woman with such deceit, cunningly trapping them and betraying Marie and your family.”

Mr Justice Smith said: “I have seen no sign of remorse. Even when eventually you had no choice but to admit killing Marie, you again portrayed yourself as the victim.

“Your allegations against Marie reached new depths – accusing her of mistreating her own daughter. I am sure that those allegations were without truth – that they were a deliberate and despicable fiction.”

The judge said an aggravating feature was that the attack was “sustained and cruel” and culminated in a multiple stabbing.

And that it had all been done while the children – a daughter, three , and a baby son – slept in their bedrooms in the three-storey house.

He said: “There is no evidence that they woke before or during the fatal attack – we can only hope that, mercifully, they did not.

“But the noise was enough to rouse the two-year-old boy next door.”

Mr Justice Smith said that it was “chilling” that Lindo had lacked any remorse following the murder and that he had been “cruel” and “calculating” when he concealed her remains in the garage and continued his lies about what had happened to her.

DETECTIVES who investigated the murder of Marie Stewart condemned the “selfishness” of her callous killer.

They said Andrew Lindo had sought only to cause further suffering for her family.

Det Supt Dick Nuttall, of West Yorkshire Police’s Homicide and Major Enquiry Team, said Lindo had done nothing but “compound” the Stewart family’s suffering by trying to blacken Marie’s name.

He spoke out minutes after 29-year-old Lindo was jailed for at least 22 years for the brutal murder.

He said: “Andrew Lindo has now been convicted of the murder of Marie Stewart, a verdict which confirms that this was a cruel and deliberate act rather than the spontaneous and momentary loss of control that Lindo has claimed in his defence.

“Lindo killed Marie in a series of brutal assaults that began in a bedroom a few feet from where their young children lay asleep and which continued through three floors of the family home before ending with Marie’s body being callously consigned to a flight bag in the garage.

“Within hours of Marie’s death – and by prior arrangement – Lindo brought his unsuspecting new girlfriend into his home before embarking on an elaborate charade that convinced everyone that Marie was still alive for several weeks.

“In his conduct since killing Marie, Lindo has continually sought to avoid or minimise his responsibility for his actions.

“Right from Lindo’s despicable behaviour and use of text and facebook messages prior to his arrest, his lies and crocodile tears in police interviews through to his descent to the ultimate low of blackening Marie Stewart’s character in the worst possible way he has shown himself to be calculating and manipulative.”

He said Lindo’s behaviour “inspired revulsion” among even the most experienced officers on the enquiry team who painstakingly exposed his lies and subterfuge to present a compelling case to the court.

“This killing had it roots in Andrew Lindo’s selfishness and whilst it is his behaviour that will make the news we shouldn’t forget that through his actions he has caused the needless death of Marie Stewart and has deprived her two young children of their loving and devoted mother.”
