Teen mom who left Baby Mary to die in New Jersey park on Christmas Eve 1984 was ... trends now

The teen mother who abandoned Baby Mary in a New Jersey park on Christmas Eve 1984 was leading an ordinary life with her husband and sons in South Carolina before police caught up with her last year. 

Catherine Crumlich, now 57, was just 17 years old when she left the one-day-old baby by a stream in Mendham, Morris County, with the umbilical cord still intact.

The death was ruled a homicide after the medical examiner determined the baby was still alive when Crumlich wrapped her in a towel and placed her inside a plastic bag.

The little girl was baptized by a local priest, Reverend Michael Drury of St. Joseph Church, who dubbed her 'Mary', and the case made national headlines. 

For 40 years, the case was cold. Then in September last year, prosecutors made the bombshell announcement that they'd tracked down Mary's parents using DNA connected to the then 19-year-old father. 

He had died but the mother, Crumlich, was alive and well, living with her family.  

Crumlich was last week convicted of juvenile delinquency and has been sentenced to a year in prison. 

Her Facebook captures the life she led under the name Catherine Snyder-Crumlich after relocating and settling in suburban Columbia, South Carolina with her new family.

Photos show her gleefully posing with her husband, David, and sons, Zachary and Noah.

Crumlich was the picture of a doting mother, attending her sons' high school baseball games, weddings and later babysitting her grandkids.

She took up a job working at a specialty grocery store called The Crescent Olive, where she was pictured grinning with coworkers around Christmastime 2018. 

But her good life came to an end when she was sentenced to one year in jail last week after pleading guilty to manslaughter.
