A jury in Prince Albert has told the presiding judge they are having a hard time reaching a decision in the case of a former teacher accused of having sex with a student 20 years ago.

The ten women and two men on the jury began considering the case of Bonnie McLachlan around 3:30 p.m. CST Thursday and, shortly before 10 p.m., called it a day.

They were set to resume deliberations Friday morning.

On Thursday night the jury told the judge that they were divided, however they did not throw in the towel.

The former teacher is accused of sexual exploitation of one of her students 20 years ago.

McLachlan, now 53, was charged after the alleged victim, who was 15 at the time, came forward with a complaint as an adult.

In closing arguments Thursday, McLachlan's lawyer told the jury that witnesses for the prosecution gave contradictory and inconsistent accounts of what happened.

The defence said the student testified that the relationship with McLachlan was an unforgettable experience, but noted the man seemed to have trouble recalling some details.

The prosecutor on the case said with 20 years gone by, some small details might be forgotten.

But the Crown lawyer told the jury there was plenty of evidence to convict.

The Crown said many elements of the alleged victim's recollections were supported by other witnesses, who had no reason to lie.

When McLachlan testified, she denied ever having sex with the Grade 9 student. McLachlan's husband also said his wife has never been unfaithful.
