A New Hampshire man has reached a plea agreement with prosecutors in the 2011 disappearance and death of a Maine woman whose toddler daughter was found abandoned in her car. Michael Petelis of Ossipee is scheduled for a plea-and-sentencing hearing at 1 p.m. on Wednesday in Carroll County Superior Court. Petelis was charged with conspiracy to commit robbery in the case of Krista Dittmeyer, of Portland, Maine. She was found in a snowmaking pond at Cranmore Mountain in Conway. The discovery came four days after her car was found idling in the ski area’s parking lot with her 14-month-old daughter unharmed inside. Anthony Papile was sentenced to 50 years in prison for Dittmeyer’s death. Trevor Ferguson was sentenced to at least seven years in prison for conspiring to rob her.
