Note found in girl's bedroom outlined plan to kill trans teen Brianna Ghey, U.K. prosecutor says

A plan to kill a 16-year-old transgender girl was found in the bedroom of one of two other teenagers accused of her murder, a U.K. court was told Tuesday.

Brianna Ghey was stabbed 28 times in the head, neck, back and chest in a park in Warrington, northwest England, on Feb. 11 this year in a crime that drew international attention.

A boy and a girl, who were aged 15 at the time and cannot be named because they are under 18, were charged with her murder and went on trial Monday. Manchester Crown Court was told that the pair, now 16 and referred to in court as girl X and boy Y, discussed killing Ghey days and weeks beforehand.
