A man has admitted murdering his ex-partner and her mother following a relationship breakdown.
Khaola Saleem, 49, and Raneem Oudeh, 22, were fatally stabbed outside Mrs Saleem's home in Solihull on 27 August.
Ms Oudeh married Janbaz Tarin, 21 in an Islamic ceremony but dumped him when she discovered he had a secret wife and children in the Middle East.
Tarin "spent the day hunting" down Ms Oudeh and her mother who were on the phone to police when he attacked.
'Two defenceless ladies'
He went on the run after killing them and was arrested three days later.
Tarin is due to be sentenced at Birmingham Crown Court later.
It was "a brutal murder of two defenceless ladies by a man who had spent the day hunting them down", West Midlands Police said.
The circumstances of the stabbing are being investigated by the Independent Office for Police Conduct (IOPC) and the force said it would accept any "learning".
Ms Oudeh and her mother were attacked at Mrs Saleem's home in Northdown Road shortly after 00:30 BST and were confirmed dead at the scene.
A post mortem examination concluded they had died from multiple stab wounds.
Tarin and Ms Oudeh met at Solihull College and were married in an Islamic ceremony but their marriage was not recognised in UK law.
Ms Oudeh, who has a two-year-old son, and Mrs Saleem, who has five other children, were both born in Syria.
Hunting them down
It emerged Ms Oudeh had dumped Tarin, of Evelyn Road, Sparkhill, Birmingham, in the weeks before his attack after learning about his other wife and children in Afghanistan.
He was abusive towards Ms Oudeh during their relationship and after they split up he repeatedly hassled his ex-partner who applied for a non-molestation order against him.
Tarin flouted that court order and, in the hours leading up to the assault, Ms Oudeh made three calls to police.
'I will kill you'
On the night of the attack he followed Mrs Saleem and her daughter to a shisha lounge before hunting them down elsewhere, police said.
Det Ch Supt Mark Payne said police were in contact with Ms Oudeh from the shisha lounge and were trying to reach her but failed to catch up with her before Tarin did.
He said: "As we were trying to get to her, she was moving on.
"We never got to the same place as she was tragically before the events unfolded."
Mrs Saleem's sister Nour Norris, said in the first six months of the year-long marriage her niece was "hiding her misery", but added that, "He used to threaten her many times 'if you leave me, I will kill you and your family'."
"One day she said to me, Auntie, I feel my life's going to end."
Mother slaughtered protecting child
Fearing for her safety Ms Oudeh went to stay with her mother, with the help of whom she secured the non-molestation order.
In the shisha lounge there was a confrontation involving Tarin, Ms Oudeh and her mother.
Tarin was swiftly ejected by staff after being overheard making threats to kill Ms Oudeh.
He left the bar, armed himself with a knife and drove to Mrs Saleem's home where he violently attacked Ms Oudeh outside the front door and then attacked Mrs Saleem as she tried to save her daughter.
Tarin was captured on CCTV fleeing the scene on foot and went into hiding, triggering a huge manhunt by West Midlands Police.
Ms Oudeh's two-and-a-half year old son is now living with Mrs Norris.
Asked if she believed the police and authorities had failed to do enough that night to stop Tarin, and in the months beforehand to protect the victim, Mrs Norris replied: "Yes we do."
"We do feel that and we feel there's a lot of women out there as well probably going through the same thing, who agree with us."
