Boy and girl convicted of murdering British transgender teenager Brianna Ghey in knife attack

A boy and a girl were found guilty Wednesday of murdering a transgender teenager in northwest England earlier this year, in a frenzied knife attack that was described as "horrific" by police.

Brianna Ghey, 16, was stabbed with a hunting knife 28 times in her head, neck, chest and back in broad daylight after being lured to a park in the town of Warrington on Feb. 11.

The convicted pair, who are identified only as girl X and boy Y, are 16 now but were 15 at the time. They denied killing Ghey, and each blamed the other for the fatal stabbing. It is not known which one or if both wielded the knife. Neither had been in trouble with police before.
