WATCH: Still Awaiting DNA In Reopened 'Baby Mary' Homicide Case That Shocked Morris County

Authorities hope there is some DNA that can help provide clues in the long cold - and now reopened - ”Baby Mary” case.

Chief Steve Crawford of the Mendham Township Police Department decided earlier this year to open a 30-year-old cold case with the hopes of solving the longest-standing mystery in the town’s storied history.

On Christmas Eve, 1984, police responded to a small waterfall off Mt. Pleasant Road in the township. Two boys had gone fishing on a reasonably warm day for the season, and found a black bag placed on a rock near the river. Inside the bag, the boys were faced with a horrific scene, one surely they have never forgotten.

It was the body of a baby who had died from exposure and hypothermia, and was estimated to have been abandoned within the past 24 hours.
