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, who is 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.
Bonser is due to be sentenced shortly.

Casey Kearney died because through no fault of her own she happened to walk on the same path as woman who wanted to kill someone.
