A woman with a history of mental health problems has been found guilty of murdering a 13-year-old stranger in a park.
Hannah Bonser, 26, stabbed Casey Kearney in a random attack in Elmfield Park, Doncaster, South Yorkshire, on Valentine's Day.
A jury at Sheffield Crown Court rejected Bonser's claim that she was guilty only of manslaughter due to diminished responsibility.
The judge, Mr Justice Cranston, said he will pass sentence at 2pm.
Bonser showed no emotion when the jury foreman returned the guilty verdict after two hours of deliberation. She sat in the dock looking ahead, as she has done throughout the week-long trial, surrounded by four prison officers.
