Lyra McKee: Woman killed in Derry was a 'rising star of investigative journalism'

Journalist Lyra McKee tweeted about the "absolute madness" in Derry in the hours before she was shot dead yesterday evening.

Ms McKee, 29, rose to prominence in 2014 after a blog post called "Letter to my 14-year-old self" in which she spoke about the struggle of growing up gay in Belfast.
