A young nurse develops a fatal illness and her doctors wonder if she was infected by one of her patients.

Forensic scientists, genetic researchers and even the police joined together to solve the mystery.

And they discovered this was no accident.

In 1994, Janice Trohan was a single mother of two young children working as a nurse in the small town of Lafayette, Louisiana.

A few years back, she started to develop some unusual symptoms and she did what most health professionals do sought the advice of her doctor.

She goes to bars during the day, she goes home with strange men.

And she's most likely contracted the disease from sleeping around.

Knowing her unborn child could be infected with HIV as well, Janice decided to end her pregnancy.

And she faced the realization of her own personal agony.
