CASTLE ROCK, Colo. -- A Douglas County woman accused of hiding the dead body of her newborn son in her college dorm room pleaded guilty Friday to concealing the death.

Prosecutors called it a fair outcome for the high-profile case.

Addie Kubisiak, 19, of Parker, Colo., had originally been charged with first-degree murder and child abuse after the decaying body of the newborn was found in her dorm room at Western State College in Gunnison, Colo., in November 2006.

Gunnison police had been tipped off by students who reported smelling a foul odor.

Kubisiak said she gave birth in the back of a pickup truck on the day before Thanksgiving.

She hid her pregnancy from her parents and the baby's father.

Last April, prosecutors dropped the first-degree murder and child abuse charges because they said they couldn't prove the infant was born alive.

The autopsy report concluded the fetus was about 40 weeks old at the time of the unattended delivery.

Kubisiak was instead charged with concealing a death, a misdemeanor.

She was charged in Douglas County because that's where the baby's birth occcured.

On Friday, Kubisiak entered a guilty plea and was sentenced to 50 hours of community service and was ordered to undergo a psychiatric examination. She could have been sentenced to up to 18 months in jail on the charge.

Kubisiak declined to speak to the court during the hearing.

During sentencing Judge Monica Gomez told Kubisiak that prosecutors had shown her "mercy." Gomez said there was no reason that Kubisak couldn't move on with her life and someday be a good mother.

Before sentencing, Gomez read a private letter from the family of the apparent father.

Because the coroner ruled the child stillborn, the father was not legally considered a victim.
