Northampton, MA (WWLP/CNN) - For days the whereabouts of a Massachusetts mother were a mystery.

On Monday, a judge ordered that the woman's boyfriend be held on $100,000 bail for improper disposal of a body and misleading authorities.

Jeb Daly, 36, pleaded not guilty in Northampton District Court Monday.

The body of 30-year-old Jessica Dana was reportedly discovered Sunday, not far from the Huntington home she shared with her three children.

Neighbors described the couple as happy and private.

No word on a motive for the alleged crime, or the cause of death.

Daly is due back in court on July 27.
