Maat said no cause of death was provided and there was no confirmation of how long the body was buried.

The Muskegon-area woman disappeared in December 2014, 11 days after giving birth to a baby girl. She went missing after reportedly going to visit the infant at a hospital.

Police got a tip (from a county jail inmate, according to WOOD-TV) about the body last week and the remains were found in Fruitland Township Friday night— buried and capped with cement.

In a statement, Maat said an active investigation is ongoing.

Roosevelt Park Police previously said a suspect is in custody who is “incarcerated for an unrelated matter.”
