GRAND RAPIDS, Mich. (WOOD) — A mother accused of killing her baby and leaving the infant’s remains in an Upper Peninsula campground toilet in 1997 is set to go to trial.

On Dec. 12, a court is set to determine if statements Nancy Ann Gerwatowski made to police about the death of her child, along with information about an abortion consideration and a lack of prenatal medical care, can be used in the trial, Detroit NBC affiliate WDIV reports.

According to a release from the state, Gerwatowski allegedly gave birth in 1997 to her baby while home alone in Newberry, and the baby died of asphyxiation. The state alleges that the baby could have survived if she had sought medical intervention.

The remains of the baby were later found in a pit toilet at the Garnet Lake Campground, located in Hudson Township, 20 miles away from Newberry. The baby was a “term or near-term infant,” according to the state.

Investigators were not able to identify the baby, who they called Baby Garnet, and the baby’s death became a cold case. That changed in 2022, when a forensic genealogist was able to track down relatives of Baby Garnet using a public DNA database.

Gerwatowski, who told investigators she was the baby’s mother, was arrested and brought back to Michigan from Wyoming state.

She has been charged with open murder, involuntary manslaughter and concealing the death of an individual. WDIV reports the concealing a death charge could be dismissed.

If convicted, she faces up to life in prison.
