A Livingston County judge in Michigan sent a woman to jail for 30 days after she was found guilty of posting another woman's contact details on a Web site where she advertised the victim was in search of casual sex.

Oceola Township resident Holly Laballister, 39, had pleaded guilty as charged before a Livingston County Circuit Court to three counts each of making illegal posts on Craigslist, which was the reason the victim received lewd and offensive telephone calls.

The accused told the judge that she had no excuse for her behavior, conceding she was wrong in attacking the character and integrity of the victim and herself.

She sought clemency, saying she is in the middle of an attempt to change her life for the better.

Her pleas fell on deaf ears with Judge Miriam Cavanaugh, acknowledging that the accused "was in a different place now," but she zeroed in on the defendant's criminal history, which includes three misdemeanor convictions and a felony conviction.

She will also spend two years on probation.

The judge said she found Laballister not much of an honest person and what she did was like a page out of the movie "Mean Girls," adding the defendant was just too old for her crime.

The accused's previous convictions included concealing and receiving stolen property; operating a vehicle while impaired; and child neglect for leaving her then 10- and 7-year-old children at a hotel all alone.

Laballister told the judge she posted the victim's telephone number thrice on Craigslist in September, where she posted that the victim was in search of a "sexual relationship." She posted the ad a second and third time because she thought it did not work the first time.

A lawyer for the victim, James Crane, said the phone calls as a result of the Craigslist post "were very graphic." He said his client had wondered for months who put her in the ad and whether she was in danger.
