Julie E. McCormick, 31, the former head of safety and security at the Idaho Department of Juvenile corrections facility in Nampa, faces up to 20 years in prison but could be released in less than a year if she successfully completes a "rider" program.
Third District Canyon County Judge Bradly Ford retained jurisdiction in the case. If McCormick, 31, does not complete the rider, she faces a mandatory sentence of five years in prison followed by up to 15 additional years.
McCormick pleaded guilty last summer to lewd conduct with a minor under 16.
McCormick engaged in sexual intercourse with the 15-year-old victim three times while he was being held at the juvenile detention center. Concerns were raised by other staff members at the center and the victim disclosed the abuse.
McCormick told investigators she fell in love with the victim.
The boy's mother spoke at the sentencing hearing, telling Ford that McCormick took away her son's dignity and shamed him.
"You brainwashed him about his past and used that to gain his trust," the boy's mother told McCormick.
Ford told McCormick she abused her position of authority and trust in taking advantage of the boy.
McCormick was also ordered to have no contact with minor boys and to pay a $5,000 civil penalty to the victim.
Earlier this month, a federal judge ruled that a whistleblower lawsuit filed against the Idaho Department of Juvenile Corrections and related to the abuse allegations brought against McCormick can move forward but that some of the claims must be dismissed.
A group of staff members at the Nampa juvenile detention center accused agency leaders of not doing enough to stop the abuse. They also contend the department is rife with cronyism and wastes taxpayer money.
The state has denied the claims.
Chief District Judge B. Lynn Winmill said the employees could not seek money damages from the agency itself, but said they could seek damages from top agency leaders.
Winmill found that the employees raised enough questions of facts in their lawsuit to merit bringing them before a jury.
