Halyna Hoisan, 29, had escaped her abusive partner in April 2025, moving away and securing a non-molestation order against him.
But Yurii Muzyka from Burlington Road in New Malden, then aged 33 and pictured, embarked on a campaign of stalking and harassment with Halyna even finding a tracker in their four-year-old daughter’s scooter.
Muzyka became obsessed with Halyna after she developed a new relationship, kicking down her door armed with a knife and a chisel when he discovered she was in the flat with another man.
He stabbed Halyna six times last August and she died at the scene. He filmed a selfie video next to her as she lay dying on the floor.
He has today been sentenced to life imprisonment to serve a minimum of 30 years.
Over the last year in London, arrests and charges for offences involving violence against women and girls have increased by 71%, while the number of rape cases where officers had secured charges have more than doubled.
Detective Chief Inspector Mark Franklin, whose team led the investigation, said: “Halyna’s murder was an appalling act of cruelty. Muzyka robbed a child of her devoted mother and parents of a loving daughter.
“Detectives worked tirelessly to bring Muzyka to justice and the successful conviction highlights the Met’s commitment to bringing dangerous men to justice and tackling violence against women and girls.”
Halyna’s family said: “The family and close friends of Halyna are grateful to the Metropolitan Police and the Crown Prosecution Service for their hard work and support in helping to secure justice for Halyna.
“Halyna was a deeply loved daughter, mother and friend whose life was taken in a cruel and senseless act of violence. Her loss has devastated everybody who knew and loved her.
“While no verdict will ever bring Halyna back, we are thankful that justice has now been served. We would now ask for privacy and space for the family.”
This was the moment he was pictured breaking into Halyna’s flat in Greenwich. Viewer discretion is advised.
