Transgender teen suicide investigation has been called off

The death of a troubled transgender teenager who begged people to fix society before she stepped in front of a tractor-trailer in Ohio has officially been deemed a suicide.

The State Highway Patrol has closed its investigation into 17-year-old Leelah Alcorn's death.

A patrol report released Wednesday says Leelah left a handwritten note on her bed saying 'I've had enough' and did an online search about runaway assistance and a Tumblr search for the word 'suicide' before walking into traffic on a suburban Cincinnati highway in December.

A note on Leelah's Tumblr blog had said she wanted her death to mean something.

It said: 'Fix society. Please.'

Leelah's selfies and poignant messages hit home among many transgender people who say they've faced disapproving families, discrimination or violence.

Her death prompted vigils, social media discussions and online petitions supporting transgender people.
