The schoolboy jailed for murdering his teacher also plotted to kill her pregnant colleague from South Yorkshire.
Will Cornick, aged 16, was sent to prison for at least 20 years after he was found guilty of stabbing to death Ann Maguire, aged 61, at Corpus Christi School in Leeds in front of horrified classmates earlier this year.
Now it has emerged Cornick also planned to slay languages teacher Sinead Miley, who lives in Campsall, Doncaster, and who was pregnant at the time of the murder in April.
The warped teenager wanted to murder 38-year-old Mrs Miley in front of other children – and had boasted of plans to kill a third teacher at the school, head of year Andrew Kellett.
Cornick fantasised about brutally taking the life of Mrs Miley’s unborn child in the atrocity which he had spent three years planning.
He stabbed Spanish teacher Mrs Maguire to death in her classroom, but was not able to carry out attacks on the other two staff members.
Mrs Miley is since believed to have had a baby girl and is currently on maternity leave.
There was no answer at her home address yesterday.

On the morning he murdered Mrs Maguire, Cornick told a girl he intended to stab Mrs Miley in the stomach ‘so as to kill her unborn child’.
The court heard ‘he had not had the slightest problem’ with the teacher and there was no explanation as to why he should target her.
Mrs Miley had been a pupil at Corpus Christi before returning as a teacher.
She was close to Mrs Maguire and her tribute to the much-loved ‘mother of the school’ was read in court.
It said: “Ann Maguire was such an amazing woman and teacher.
“She taught me when I was a pupil and supported me in my career since I have been teaching.
“Ann loved her job and wanted all her kids to work hard and reach their full potential.”
Cornick was told he would stay locked up for a minimum of 20 years.
