When she is sentenced in August a Milwaukee woman faces up to 18 months in prison.
45-year-old Karin Luttinen entered a guilty plea to one felony count of concealing the death of a child Monday.
The body of a newborn was found in April 2009 and investigators began calling her baby Theresa.
The body had been found in the Town of Theresa.
Years later, a DNA analysis of evidence found at the scene led authorities to Luttinen.
She reached a plea agreement with prosecutors.
