Beverly man pleads guilty to role in park slaying

A Beverly man has pleaded guilty to playing a role in the death of a man at a park two years ago. Adam Martin, 19, was sentenced Monday in Salem Superior Court to up to 15 years in prison after he pleaded guilty to manslaughter in connection with the March 2011 death of James Vernazarro, 26. The arranged fight was sparked by a dispute regarding a 17-year-old girl. Prosecutors said Martin, who was 17, brought an aluminum baseball bat, which he used to strike Vernazarro in the head and the hip.
