More details have emerged about the psychiatrist who was said to be treating Batman killer James Holmes before he allegedly opened fire on a Colorado movie theater killing 12 people and injuring 58. 

Dr Lynne Fenton - who is said to specialize in schizophrenia and 'threat assessment' - may become the subject of a number of lawsuits if it emerges she could have prevented the massacre. 

Her job as part of the 'threat assessment' team is to alert authorities if any student is considered dangerous or violent.

According to legal documents filed by Holmes’ lawyers seeking to find out who leaked information about the notebook he sent to Dr Fenton, the book contained ‘a roadmap to a massacre’ and stick figures brandishing guns shooting at other stick figures.

In the legal motion, Holmes’ lawyers described him as a ‘psychiatric patient’ of Dr Fenton’s but did not disclose how long he had been under her care.
