Marissa Fields, a student at Wichita State University, was arrested and released Tuesday after she posted a $100,000 bond, according to court records.
On Dec. 26, a family member called the Olathe Police Department and reported the newborn's death, a spokesman for the department tells PEOPLE. Fields told police that she "had given birth to a child."
"She is going to plead not guilty," her defense attorney Carl Cornwell tells PEOPLE. She is expected to attend a court hearing on August 20. "Say some prayers for her," Cornwell adds.
For now, few details have been released surrounding the baby's death. "I'm just now getting the investigating file. I'm going to look at it, talk with the family, calm everything down and take a close look at what's going on here," Cornwell says.
Fields, who was a student since last year, was enrolled for the fall semester, a university spokesman tells PEOPLE.
