Teen Pleads Guilty in Dartmouth Murders

One of two teenagers arrested in the slayings of two Dartmouth College professors pleaded guilty to reduced charges but did not give a motive for the stabbings.

James Parker, 17, agreed to testify against co-defendant Robert Tulloch in a deal that could make him eligible for parole at 41.

Parker pleaded guilty to being an accomplice to second-degree murder in the death of Susanne Zantop, 55. Prosecutors said they will recommend a sentence of 25 years to life after Parker testifies.

Tulloch, 18, is accused of murdering Zantop and her husband, Half, 62, at their home Jan. 27.
