After an hourlong search in below-freezing temperatures, Eckersley then relayed the correct location and led officers to the area, police said in a statement.

The baby was treated by emergency medical technicians and then taken to a hospital for treatment. Investigators said the baby weighed 4 pounds.

The 26-year-old and daughter of Boston Red Sox legend and former NESN broadcaster Dennis Eckersley, was arrested on an unrelated warrant out of Concord District Court for endangering the welfare of a child and was charged with reckless conduct in connection with the most recent incident, police said.

According to WMUR, Eckersley has pleaded not guilty to all charges.

Her family said they found out about the incident from the news and did not know she was pregnant, according to a statement from the family.

We are utterly devastated by the events that unfolded on Christmas night when our daughter Allie delivered a baby while living in a tent, the Eckersley family said in a statement. It is heartbreaking that a child was born under such unthinkable conditions and in such tragic circumstances. We learned with everyone else from news reports what happened and are still in complete shock.Read more: Woman gave birth in NH woods, misled responders searching for child, reports say
