A judge on Tuesday ordered a former Lawrence High School teacher convicted of a sex crime to remain in jail until her sentencing in October.

Douglas County District Judge Stephen Six ruled that Meredith Kane, 24, violated her bond, based on allegations from prosecutors that she has had contact with the victim, a 16-year-old boy, at least five times since her guilty plea July 2.

Kane was arrested and booked into jail Monday and now faces an additional misdemeanor charge of violating a protective order, which barred her from contact with the victim or witnesses in the case. She will remain in jail at least until her October sentencing.

Kane pleaded guilty in July to one count of aggravated indecent liberties with a child. The acts occurred between August 2006 and March of this year with a male student who was 15 at the time.

According to a motion prosecutors filed, family friends of the victim reported to police Sunday that they saw the boy getting out of a car driven by Kane. The boy told a police detective he had been with Kane five times since her guilty plea, according to the motion.

During Tuesday’s hearing on bond revocation, Kane’s attorney, James Rumsey, introduced a letter that he said the victim had written to Kane.

“It doesn’t suggest that there wasn’t contact, but I want to make it very clear that the initiation was on his part, not my client’s,” Rumsey said.

But Six said prosecutors’ affidavit documented multiple instances of telephone and in-person contact, some of which they believe Kane initiated. Six said it was Kane’s responsibility as the adult to honor her bond agreement and a court order.

Her next court appearance on the new misdemeanor charge will be Oct. 2.

She already faces a prison sentence of between five and 20 years for her aggravated indecent liberties conviction. Rumsey has planned to ask for a lesser sentence at sentencing, now scheduled for Oct. 29.

Douglas County District Attorney Charles Branson said a possible misdemeanor conviction for violating a protective order carries a sentence of up to one year in jail. He said the recent arrest probably wouldn’t greatly affect the sentencing on the felony conviction because prosecutors have sought a prison term since early days of the case.

“With the bond being revoked, we’re asking that start much sooner,” Branson said.

The Lawrence school board suspended Kane after she was arrested in March, and the board voted in May not to renew the first-year English teacher’s contract.

One LHS student who attended Tuesday’s hearing said this week’s events in the case surprised many people. Senior Jenny Maranell said she was an English office aide when Kane taught at the high school.

“She always seemed really nice. I never really thought that anything like this would ever happen,” she said.
