RED DEER, Alta. - A former central Alberta teacher facing decades-old sex charges has pleaded guilty to one count of rape.

Warren Fertig, who is 72, was supposed to stand trial this week in Red Deer.

But court was told Tuesday that a resolution had been reached in the case.

The allegations of rape and sexual intercourse with an underage student dated back to when Fertig was a teacher in the 1970s.

He was charged in September 2011 after a woman came to police and said she had sex with Fertig when she was between 12 and 15 years old.

The defence requested a forensic assessment and sentencing is expected to take place on Jan. 17.
