CALDWELL -- A former juvenile corrections nurse accused of sexually abusing boys incarcerated at the facility where she worked has accepted a plea deal that rids her of a child sex charge.

Prosecutors amended a charge of sexual battery on a minor to aggravated assault Friday, the same day 41-year-old Valerie Lieteau entered her guilty plea.

Because the defendant did not plead guilty to a sexual crime, she will not be required to register as a sex offender.

Lieteau was originally accused of drugging and having sex with at least four boys in the Idaho Department of Juvenile Corrections' Nampa facility between 2008 and 2011.

According to a tort claim filed by the alleged victims and their families, Lieteau gave the teenagers prescription medications and street drugs. She's accused of having sex with one 15-year-old in the nurses' office while another employee acted a lookout.

When one of the boys was released, Lieteau made several trips to his hometown and continued the sexual relationship, according to the tort.

Attorney Bruce Skaug said the teens tried to alert other officials at the juvenile facility about the abuse, but were ignored.

Lieteau was arrested in California in June 2015 and extradited back to Idaho. She originally faced two counts of sexual battery of a minor and two counts of sexual contact with a juvenile inmate, offenses that could have carried a possible life sentence.

Aggravated assault is punishable by a maximum of five years in prison.

The Canyon County Prosecutor's Office said in a statement the plea deal was reached after a discussion with the victims and Skaug. Lieteau must relinquish her nursing license for 10 years as part of the agreement, prosecutors say.

The prosecutor's office declined to comment further.

Skaug said he was unhappy with the plea deal Lieteau had received in the criminal case, but will "absolutely" be proceeding with the tort claim against the juvenile corrections center.

He said the outcome was particularly unfair to the victims of the sexual abuse, none of whom had committed serious crimes before landing in the juvenile lock-up.

"They will have spent more time incarcerated for petty crimes for Valerie Lieteau will for sexually abusing teenagers," Skaug said.

The lawyer said he was also disappointed the amended charge will keep Lieteau off the sex offender registry.

"She is a sex offender, and should be treated like a sex offender for the rest of her life," he said.

Lieteau is set for sentencing May 31. She is currently free on a $100,000 bond.
