Transgender killer who murder three kids was ex-student who made 'manifesto' and maps of building

A 28-year-old, who identified as transgender, has shot dead three children aged nine and three adults at a private Christian school in Nashville, Tennessee.

Audrey Elizabeth Hale, who was once a student there, was killed by police after a confrontation with officers following the attack at the Covenant School.

Police said the "lone zealot", who lived in Nashville, was armed with two assault-type weapons, and a handgun.

Hale had a manifesto and detailed maps of the school, and entered the building by shooting through a door before the killings.
