She left “Baby Mary” in Woods around Christmas and then became a suburban mother. Now she is being brought to trial

Mary Crumlich, 57, pleaded guilty to manslaughter on Feb. 28

A woman who left her newborn daughter in a plastic bag in a New Jersey park 40 years ago has been sentenced to 364 days in prison.

Mary Crumlich, 57, who lives in Columbia, South Carolina, pleaded guilty to manslaughter on Feb. 28. She was sentenced earlier this month.

She will serve her sentence at the Morris County Correctional Facility in New Jersey, the Morris County Prosecutor's Office said in a statement.

Crumlich was 17 when her baby died.

According to Fox News, she was linked to the case after authorities obtained a DNA profile of the infant.

The baby was discovered by two boys in a wooded area in Mendham Township on Christmas Eve 1984.

The girl's body was found in a plastic bag wrapped in a towel. Her umbilical cord was still attached.

Authorities said the girl was still alive at the time of birth.

Because her identity was unknown when she was found, a priest at St. Joseph's Church baptized her and gave her the name Maria.

“Over the past nearly four decades, investigators have vigorously pursued every lead to identify Baby Mary and learn more about the circumstances that led to her discovery in the woods,” the Morris County Prosecutor’s Office said in a statement. “Using new technology, the networking of law enforcement agencies in three states and old-fashioned police work, investigators were recently able to identify Baby Mary’s birth father and mother.”

According to authorities, there was no evidence that the baby's father, now deceased, was aware of the child's birth and death.

Morris County Prosecutor Robert J. Carroll said in the news release that the case was solved “through new forensic DNA technology combined with traditional field police work conducted in multiple states.”
