A British dad who claimed he stabbed his 14-year-old daughter to death in a “freak accident” while “mucking about” in the kitchen was found guilty of murder on Monday.

Simon Vickers, 50, was convicted after the jury deliberated for less than 14 hours in the controversial death of teen Scarlett Vickers, who bled to death after being stabbed in the chest in the family home in Darlington on July 5 — with her dad claiming he thought he threw tongs at her rather than a knife.

But jurors were swayed by a forensics expert who testified that the angle of the 8-inch kitchen knife that struck Scarlett suggested she was “firmly” stabbed, the BBC said in a report.

Simon Vickers is now due to be sentenced on Feb. 10.

“We may never know why or what caused Simon Vickers to do what he did that night,” Durham Police Detective Superintendent Craig Rudd told reporters after the verdict, the outlet reported. “Sadly, today’s verdict will not bring Scarlett back, but he will now face the consequences of his actions.”

Simon Vickers testified in Teesside Crown Court that he and his wife, Sarah Hall, were playing around in the kitchen with Scarlett after he downed four glasses of wine while watching soccer on TV.

“We were having harmless fun,” he told jurors. “There was no knife in the equation. I was throwing a pair of tongs as far as I was aware.

“Then she just stopped breathing. There was nothing. Her eyes just went like a doll’s eyes.”

But Jennifer Bolton, a forensics expert called to the stand by prosecutors, testified that it was “practically impossible” for a knife like the one that killed Scarlett could have caused the fatal injury by being thrown.

Bolton said the knife was being held “tightly” with a firm grip when it caused the fatal four-inch wound.

Vickers’ lawyer told the court his client was already serving a life sentence after his daughter’s death.
