CONCORD, N.H. — The New Hampshire attorney general says one of three defendants in the disappearance and death of a Maine mother last year will plead guilty.

Attorney General Michael Delaney says Anthony Papile of Ossipee will enter a plea and be sentenced Thursday.

Papile is charged with second-degree murder in the death of 20-year-old Krista Dittmeyer of Portland, Maine.

Dittmeyer’s car was found idling in the parking lot of a North Conway ski area in April 2011 with her 14-month-old baby unharmed inside. Dittmeyer’s body was found nearby four days later.

Senior Assistant Attorney General Jane Young would not say what charge Papile would plead to.

Jesse Friedman, the public defender representing Papile, would only confirm that his client is scheduled for a plea and sentencing Thursday.

Prosecutors say Dittmeyer was lured to a friend’s apartment and clubbed by two men who plotted to steal drugs and money from her.
